I was born in Mexico City surrounded by big buildings, a lot of cars and one of the most contaminated environments in the world. When I was 9 years old my family moved to Tijuana in North West Mexico and from this vantage point, on the wrong side of the most famous border town in the world, I became acquainted with American culture. I grew up under the American way of life, meaning in a third-world city ridden with poverty, corruption, drug trafficking, prostitution, industry and an immense hate for foreigners from the South.
Through my school years, I probably heard a couple of times how minerals are acquired and how mining has brought “prosperity” and “progress” to humanity. I mean, even my family name comes from Cornwall, known for its mining sites. The first Straffon to arrive from England to Mexico did so around 1826 in Real del Monte in the State of Hidalgo (another mining town!). However, it is only recently, since I have started following the wonderful work being done in Thacker Pass by Max Wilbert and Will Falk that the horrors of mining came into focus and perspective.
What is mining? You smash a hole in the ground, go down the hole and smash some more then collect the rocks that have been exposed and process them to make jewelry, medicines or technology. Sounds harmless enough. It’s underground and provides work and stuff we need, right? What ill could come out of it? After doing some digging (excuse the pun), I feel ashamed of my terrible ignorance. Mine is the ignorance of the many. This ignorance is more easily perpetuated in a city where all the vile actions are done just so we can have our precious electronics, vehicles and luxuries.
Mine Inc.
Mining, simply put, is the extraction of minerals, metals or other geological materials from earth including the oceans. Mining is required to obtain any material that cannot be grown or artificially created in a laboratory or factory through agricultural processes. These materials are usually found in deposits of ore, lode, vein, seam, reef or placer mining which is usually done in river beds or on beaches with the goal of separating precious metals out of the sand. Ores extracted through mining include metals, coal, oil shale, gemstones, calcareous stone, chalk, rock salt, potash, gravel, and clay. Mining in a wider sense means extraction of any resource such as petroleum, natural gas, or even water.
Mining is one of the most destructive practices done to the environment as well as one of the main causes of deforestation. In order to mine, the land has to be cleared of trees, vegetation and in consequence all living organisms that depend on them to survive are either displaced or killed. Once the ground is completely bare, bulldozers and excavators are used to smash the integrity of the land and soil to extract the metals and minerals.
Mining comes in different forms such as open-pit mining. Like the name suggests, is a type of mining operation that involves the digging of an open pit as a means of gaining access to a desired material. This is a type of surface mining that involves the extraction of minerals and other materials that are conveniently located in close proximity to the surface of the mining site. An open pit mine is typically excavated with a series of benches to reach greater depths.
Open-pit mining initially involves the removal of soil and rock on top of the ore via drilling or blasting, which is put aside for future reclamation purposes after the useful content of the mine has been extracted. The resulting broken up rock materials are removed with front-end loaders and loaded onto dump trucks, which then transport the ore to a milling facility. The landscape itself becomes something out of a gnarly science-fiction movie.
Once extracted, the components are separated by using chemicals like mercury, methyl-mercury and cyanide which of course are toxic to say the least. These chemicals are often discharged into the closest water sources available –streams, rivers, bays and the seas. Of course, this causes severe contamination that in turn affects all the living organisms that inhabit these bodies of water. As much as we like to distinguish ourselves from our wild kin this too affects us tremendously, specially people who depend on the fish as their staple food or as a livelihood.
One of the chemical elements that is so in demand in our current economy is Lithium. Lithium battery production today accounts for about 40% of lithium mining and 25% of cobalt mining. In an all-battery future, global mining would have to expand by more than 200% for copper, by a minimum of 500% for lithium, graphite, and rare earths, and far more for cobalt.
Lithium – Isn’t that a Nirvana song?
Lithium is the lightest metal known and it is used in the manufacture of aircraft, nuclear industry and batteries for computers, cellphones, electric cars, energy storage and even pottery. It also can level your mood in the form of lithium carbonate. It has medical uses and helps in stabilizing excessive mood swings and is thus used as a treatment of bipolar disorder. Between 2014 and 2018, lithium prices skyrocketed 156% . From 6,689 dollars per ton to a historic high of 17,000 dollars in 2018. Although the market has been impacted due to the on-going pandemic, the price of lithium is also rising rapidly with spodumene (lithium ore) at $600 a ton, up 40% on last year’s average price and said by Goldman Sachs to be heading for $676/t next year and then up to $707/t in 2023.
Lithium hydroxide, one of the chemical forms of the metal preferred by battery makers, is trading around $11,250/t, up 13% on last year’s average of $9978/t but said by Goldman Sachs to be heading for $12,274 by the end of the year and then up to $15,000/t in 2023. Lithium is one of the most wanted materials for the electric vehicle industry along cobalt and nickel. Demand will only keep increasing if battery prices can be maintained at a low price.
Simply look at Tesla’s gigafactory in the Nevada desert which produces 13 million individual cells per day. A typical Electronic Vehicle battery cell has perhaps a couple of grams of lithium in it. That’s about one-half teaspoon of sugar. A typical EV can have about 5,000 battery cells. Building from there, a single EV has roughly 10 kilograms—or 22 pounds—of lithium in it. A ton of lithium metal is enough to build about 90 electric cars. When all is said and done, building a million cars requires about 60,000 tons of lithium carbonate equivalent (LCE). Hitting 30% penetration is roughly 30 million cars, works out to about 1.8 million tons of LCE, or 5 times the size of the total lithium mining industry in 2019.
Considering that The United States-Mexico-Canada Agreement (USMCA) is being negotiated, lithium exploitation is a priority as a “must be secured” supply chain resource for the North American corporate machine. In 3 years, cars fabricated in these three countries must have at least 75% of its components produced in the North American regionso they can be duty-free. This includes the production of lithium batteries that could also become a profitable business in Mexico.
Sonora on Lithium
In the mythical Sierra Madre Occidental (“Western Mother” Mountain Range) which extends South of the United States, there is a small town known as Bacadéhuachi. This town is approximately 11 km away from one of the biggest lithium deposits in the world known as La Ventana. At the end of 2019, the Mexican Government confirmed the existence of such a deposit and announced that a concession was already granted on a joint venture project between Bacanora Minerals (a Canadian company) and Gangfeng Lithium (a Chinese company) to extract the coveted mineral. The news spread and lots of media outlets and politicians started to refer to lithium as “the oil of the future.”
Sonora Lithium Ltd (“SLL”) is the operational holding company for the Sonora Lithium Project and owns 100% of the La Ventana concession. The La Ventana concession accounts for 88% of the mined ore feed in the Sonora Feasibility Study which covers the initial 19 years of the project mine life. SLL is owned 77.5% by Bacanora and 22.5% by Ganfeng Lithium Ltd.
Sonora holds one of the world’s largest lithium resources and benefits from being both high grade and scalable. The polylithionite mineralisation is hosted within shallow dipping sequences, outcropping on surface. A Mineral Resource estimate was prepared by SRK Consulting (UK) Limited (‘SRK’) in accordance with NI 43-101.”
The Sonora Lithium Project is being developed as an open-pit strip mine with operation planned in two stages. Stage 1 will last for four years with an annual production capacity of approximately 17,500t of lithium carbonate, while stage 2 will ramp up the production to 35,000 tonnes per annum (tpa). The mining project is also designed to produce up to 28,800 tpa of potassium sulfate (K2SO4), for sale to the fertilizer industry.
On September 1st, 2020, Mexico’s President, Andres Manuel Lopez Obrador, dissolved the Under-secretariat of Mining as part of his administration’s austerity measures. This is a red flag to environmental protection as it creates a judicial void which foreign companies will use to allow them greater freedom to exploit more and safeguard less as part of their mining concession agreements.
Without a sub-secretariat, mediation between companies, communities and environmental regulations is virtually non-existent. Even though exploitation of this particular deposit had been adjudicated a decade ago under Felipe Calderon’s administration, the Mexican state is since then limited to monitoring this project. This lack of regulatory enforcement will catch the attention of investors and politicians who will use the situation to create a brighter, more profitable future for themselves and their stakeholders.
To my mind there is a bigger question – how will Mexico benefit from having one of the biggest deposits of lithium in the world? Taking into account the dissolution of the Mining sub-secretariat and the way business and politics are usually handled in Mexico, I do wonder who will be the real beneficiaries of the aforementioned project.
Extra Activism
Do not forget, mining is an integral part of our capitalist economy; mining is a money making business – both in itself and as a supplier of materials to power our industrial civilization. Minerals and metals are very valuable commodities. Not only do the stakeholders of mining companies make money, but governments also make money from revenues.
There was a spillage in the Sonora river in 2014. It affected over 22,000 people as 40 million liters of copper sulfate were poured into its waters by the Grupo Mexico mining group. Why did this happen? Mining companies are run for the profit of its stakeholder and it was more profitable to dump poison into the river than to find a way to dispose it with a lower environmental impact. Happily for the company stakeholders, company profit was not affected in the least.
Even though the federal Health Secretariat in conjunction with Grupo México announced in 2015 the construction of a 279-million-peso (US $15.6-million) medical clinic and environmental monitoring facility to be known as the Epidemiological and Environmental Vigilance Unit (Uveas) to treat and monitor victims of the contamination, until this day it has not been completed. The government turned a blind eye to the incident after claiming they would help. All the living beings near the river are still suffering the consequences.
Mining is mass extraction and this takes us to the practice of “extractivism” which is the destruction of living communities (now called “resources”) to produce stuff to sell on the world market – converting the living into the dead. While it does include mining – extraction of fossil fuels and minerals below the ground, extractivism goes beyond that and includes fracking, deforestation, agro-industry and megadams.
If you look at history, these practices have deeply affected the communities that have been unlucky enough to experience them, especially indigenous communities, to the advantage of the so-called rich. Extractivism is connected to colonialism and neo-colonialism; just look at the list of mining companies that are from other countries – historically companies are from the Global North. Regardless of their origins, it always ends the same, the rich colonizing the land of the poor. Indigenous communities are disproportionately targeted for extractivism as the minerals are conveniently placed under their land.
While companies may seek the state’s permission, even work with them to share the profits, they often do not obtain informed consent from communities before they begin extracting – moreover stealing – their “resources”. The profit made rarely gets to the affected communities whose land, water sources and labor is often being used. As an example of all of this, we have the In Defense of the Mountain Range movement in Coatepec, Veracruz. Communities are often displaced, left with physical, mental and spiritual ill health, and often experience difficulties continuing with traditional livelihoods of farming and fishing due to the destruction or contamination of the environment.

Planet of the Humans, an outstanding documentary by Jeff Gibbs and Michael Moore, drew a lot of attention when it was originally published on YouTube for free. But a coordinated censorship campaign lead to it being taken down from YouTube where it had been viewed 8.3 million times.
“Day 4: Still banned. Our YouTube channel still black. In the United States of America. The public now PROHIBITED from watching our film “Planet of the Humans” because it calls out the eco-industrial complex for collaborating with Wall Street and contributing to us losing the battle against the climate catastrophe. As the film points out, with sadness, some of our environmental leaders and groups have hopped into bed with Bloomberg, GoldmanSachs, numerous hedge funds, even the Koch Bros have found a way to game the system— and they don’t want you to know that. They and the people they fund are behind this censorship. We showed their failure and collusion, they didn’t like us for doing that, so instead of having the debate with us out in the open, they chose the route of slandering the film — and now their attempt at the suppression of our free speech. “Democracy Dies in Darkness.” Fascism is given life when “liberals” employ authoritarian tactics. Or sit back and say nothing. Who will speak up against blocking the public from seeing a movie that a group of “green capitalists” don’t want you to see? Where is the Academy? Where is the International Documentary Association? If you leave us standing alone, your film may be next. What is pictured above could be the darkened screen of your next movie. Do we not all know the time we are living in? All this energy spent trying to save our film when we should be saving the planet — but the green capitalists have once again provided a distraction so that no one will see what they’re really up to, so that no one will call them out for thinking we’re going to end the climate crisis by embracing or negotiating with capitalism. We call BS to that — and that is why our film has vanished. But not for long. We will not be silenced. We, and hundreds of millions of others, are the true environmental movement — because we know the billionaires are not our friends.”
Now the movie is up on YouTube again
Michael Moore presents Planet of the Humans, a documentary that dares to say what no one else will — that we are losing the battle to stop climate change on planet earth because we are following leaders who have taken us down the wrong road — selling out the green movement to wealthy interests and corporate America. This film is the wake-up call to the reality we are afraid to face: that in the midst of a human-caused extinction event, the environmental movement’s answer is to push for techno-fixes and band-aids. It’s too little, too late.
Removed from the debate is the only thing that MIGHT save us: getting a grip on our out-of-control human presence and consumption. Why is this not THE issue? Because that would be bad for profits, bad for business. Have we environmentalists fallen for illusions, “green” illusions, that are anything but green, because we’re scared that this is the end—and we’ve pinned all our hopes on biomass, wind turbines, and electric cars? No amount of batteries are going to save us, warns director Jeff Gibbs (lifelong environmentalist and co-producer of “Fahrenheit 9/11” and “Bowling for Columbine“). This urgent, must-see movie, a full-frontal assault on our sacred cows, is guaranteed to generate anger, debate, and, hopefully, a willingness to see our survival in a new way—before it’s too late. https://planetofthehumans.com/
From Julia Barnes, the award-winning director of Sea of Life, Bright Green Lies investigates the change in focus of the mainstream environmental movement, from its original concern with protecting nature, to its current obsession with powering an unsustainable way of life. The film exposes the lies and fantastical thinking behind the notion that solar, wind, hydro, biomass, or green consumerism will save the planet. Tackling the most pressing issues of our time will require us to look beyond the mainstream technological solutions and ask deeper questions about what needs to change.
Ethnic Kui Indigenous people have for generations mined the mountains and streams of Cambodia’s Romtom commune for their livelihoods. But those traditions shifted as Delcom, a Malaysian-owned gold-mining company, began digging up the land in the early 2010s and confronting artisanal miners with armed guards. Miners at that time said their peers had gone abroad to seek new jobs, while those who remained were broke.
Since 2009, Cambodia has had a legal process by which Indigenous communities can obtain legal title to their traditional land.
Of around 455 Indigenous communities in Cambodia, 33 have been granted land titles.
People who have engaged in the Indigenous land titling process say it is time-consuming and arduous, and that even successful claimants are often granted title to just a fraction of their customary land.
This year, Cambodia has launched a review of its communal land titling process. Even people involved in the review are unsure what prompted it or what impacts the review might have.
Several years later, the community faced new pressure from Delcom. The company began stretching itself further, eating into farmland, and again choking the Kui communities’ livelihoods. With renewed frustrations, residents spoke to environmental activists; during the interviews one woman named a person she was told was in charge of the area, without knowing that the man is a powerful general named in several notorious land disputes.
Unbeknown to the residents living around it, the Delcom gold mine had been transferred from a Malaysian conglomerate to Chinese owners, a transaction whose details remain scant.
Under Cambodian law, a mechanism exists that should allow the Kui to make a case to own and use land they have been occupying for generations. However, as of late 2020, the Kui residents are still fighting for the rights to their land, and, like most of Cambodia’s Indigenous communities, have not successfully made a legal claim.
In reality, Cambodia’s strong laws for protecting Indigenous land are bogged down by a time-consuming process and blocked by land concessions.
This year, as land prices surge and the country is extracting private land from protected areas, the Cambodian government is reviewing its Indigenous communal land titling application process, and Indigenous land use in general. What motivated the reevaluation, and how Indigenous land rights might change as a result, is still opaque. But Indigenous NGOs and advocates say that truly protecting Indigenous cultures and their ties to Cambodia’s forests would require fundamental changes to the process of registering and protecting Indigenous land rights.

The process for Indigenous land titling
Cambodia agreed to the U.N.’s declaration on Indigenous rights in 2007, which explicitly grants Indigenous groups authority over land they’ve held “by reason of traditional ownership,” to use or develop as they please. Two years later, the government enshrined the right of Indigenous groups to hold their traditional land, and the procedure for doing so, into its laws.
Since then, 33 communities have received land rights, or just 7% of the total 455 Indigenous communities known in Cambodia, according to data compiled by Cambodian nonprofit network NGO Forum.
The process is arduous. Before an Indigenous village and the NGO assisting it can begin surveying land to claim ownership, an individual Indigenous community has to gain recognition from its provincial authorities and Cambodia’s Rural Development Ministry, and then register legally with the Interior Ministry. About a third of Cambodia’s Indigenous communities have done so, according to NGO Forum data.
The next step is mapping and designating areas for homes, rotational farmland, ancestral burial grounds, and spirit forests and mountains. Usually a local NGO steps in to assist with GPS coordinates and creating the map. They then present the map to the Land Ministry, which confirms the area, ensures it doesn’t overlap with other land users, and finally issues the title.
Indigenous land titles also come with a condition to protect a piece of the forest, usually tied to the community as ancestral burial sites and spaces of spiritual significance.
Currently, 86 communities have applications in the works, while an additional 33 have received land titles in the end, according to NGO Forum data.

Cambodia’s conflict-ridden land records
All property records in Cambodia were destroyed during the 1975-1979 reign of the Khmer Rouge, part of the totalitarian leaders’ efforts to revoke private property and establish Cambodia as a radical, isolated agrarian state.
Cambodia’s Land Law was finally restored in 2001, but land ownership remains ambiguous and many, particularly in the provinces, have “soft titles” from the local government, rather than sturdier “hard titles” granted by the national government. Others live without land titles at all, since proving ownership is complex, and generally relies on proving a family or community has occupied land for the long term.
Both Indigenous and non-Indigenous land ownership nationwide has also been complicated by an economic land concession campaign that began in the early 2000s, in which the government granted huge swaths of public land to private companies. Though the program was suspended after receiving sharp international criticism for deforestation and land grabbing in and around concessions, the government has continued to grant huge territories with little public explanation.
Cambodian Prime Minister Hun Sen announced last July that people who can prove they’ve lived in a protected area for more than 10 years can be granted land titles, which spurred a rapid surveying campaign in Mondulkiri province in the second half of the year and revealed a number of illegal land grants issued by local and national officials.
Simultaneously, land prices are rising throughout the country, with land in Mondulkiri’s city center costing as much as $1,500 per square meter (about $140 per square foot), according to some real estate agents, and provincial land also increasing in value as the country develops more tourism projects.
Pros and cons of the current process
Pheap Sophea, a natural resources governance program manager for the NGO Forum, said Cambodia’s Indigenous land titling program has been successful in working to “preserve traditional culture, good habits, protect land security and improve the livelihoods of Indigenous communities,” both for the communities who received the land and those in the process. However, he says several aspects of the process need to be simplified and clearly communicated to the Indigenous groups who are in the process of or eligible for receiving land titles.
Grassroots NGOs supporting Indigenous communities have more pointed critiques.
Yun Lorang, coordinator for Cambodia Indigenous People Alliance, says the process takes too long, at least three years.
“We don’t have an experience of success yet,” he told Mongabay.
Lorang says the land titles, when approved, do secure some of the land that Indigenous communities hold, but never cover the whole area they’ve been using for decades. The law allows only state-owned land to be allocated as Indigenous land, and limits the amount of area that Indigenous groups can use for spiritual purposes: 7 hectares (17.3 acres) each for spirit forest area and for ancestral burial ground.
“Sacred and burial land are bigger than 7 hectares,” Lorang said. “Based on customary rules and practices, community land’s size is more than 5,000 hectares [12,400 acres], but the government offers only 1,000 to 1,500 hectares [2,500-3,700 acres].”
Indigenous land claims often overlap with company developments, and when that happens, it’s usually the economic interest that wins out.
When the Lower Sesan II hydropower dam flooded its reservoir, it split two Indigenous villages down the middle. Thousands of families went to live in rows of cookie-cutter houses along National Road 78, while a small group picked up the remains of their homes and stood their ground.
The Bunong Indigenous people of Kbal Romeas, one of the two villages along the Sesan River that were hit immediately by the dam’s floods, lost their homes, school, health center, and critically, ancestral burial ground, to the floods.
Calling themselves “Old Kbal Romeas,” the remaining residents rebuilt their homes on a cleared section of land that was part of their rotational agriculture area, though one woman said she felt the new territory was a “bad land” that brought her trouble.
Old Kbal Romeas successfully gained recognition as an official Indigenous community from the Interior Ministry and were permitted to rebuild their homes by Stung Treng province authorities in 2018. They began plotting their land with the grassroots group Cambodian Indigenous People’s Organization in preparation for a title application, but found they were competing with a rubber concession that had reasserted its territorial claims.
“We’re concerned we can’t defeat them. They are powerful,” Old Kbal Romeas community leader Sran Lanj said in September 2020. “My community and I are powerless. They put pressure on us to accept [a deal], and it’s like they are compelling us to give our land to them.”
After mapping their territory for an Indigenous land title, Old Kbal Romeas residents say they have around 7,000 hectares (17,300 acres) of land — half of which is flooded — but they still want the control over the area.
The government instead offered them 941 hectares (2,325 acres), and the residents refused to accept.
“Nine hundred and forty-one [hectares] of land for this number of families is enough,” said Stung Treng provincial land department director Minh Sichay. “It should be acceptable. Why do they demand 3,500?”
The review
NGOs, the U.N. human rights commission and a conservation group all confirmed to Mongabay that Cambodia’s Interior Ministry is reviewing both registered Indigenous communities and their communal land rights — both applications and granted titles — though none of the stakeholders said they knew the motive for the review.
Sophea, from the NGO Forum, said his organization was working with the ministry to survey Indigenous communities about their understanding and experience of the land titling process, and how Indigenous communities ultimately use the land.
The survey will involve 22 Indigenous communities, seven of which had received community land titles and 15 in the process of registering their land, Sophea said.
He said the survey would not be complete until mid-2021, or maybe later, due to Cambodia’s new surge in COVID-19 cases. Interior Ministry spokesperson Khieu Sopheak said the ministry was only probing the program but did not know what would happen as a result, and Land Management ministry spokesperson Seng Lot did not respond to questions, telling a reporter on the phone he’s “very, very busy.”
Pradeep Wagle, the U.N. human rights representative in Cambodia, said in a written statement that the government is following through with recommendations made by the organization’s human rights experts in a 2019 review. Among dozens of recommendations, U.N. representatives urged Cambodia to simplify the process for allocating land to Indigenous communities. Wagle reiterated the suggestion in his response, though he did not provide details on how the laws or process should change.
“The existing process is complex, lengthy, expensive and surrounded by several technical formalities,” he said. “The suggested reforms ensure cost effectiveness and propose reasonable and less cumbersome steps for Indigenous communities to obtain a collective land title.”
Before this review, Sophea said his organization had worked with the interior, rural development, and land ministries to make improvements on the titling system, such as shortening the registration process and simplifying the requirements for preliminary maps made by the communities.
Notably absent, Sophea says, was the Environment Ministry, which has the designation over all terrestrial protected spaces. The ministry has the power to reject an Indigenous land title application if it overlaps with a protected area, and has already exercised that right for nine communities, according to NGO Forum data.
Sophea says that throughout 2019 and 2020, the NGO Forum organized a series of meetings on issues relating to land governance and overlaps between Indigenous customary rights and protected areas, but, despite being invited to three meetings, Environment Ministry officials did not attend.
Lorang, the Indigenous leader, agreed, noting that attempts to complete land title applications are thwarted most often by local governments and the Environment Ministry, especially in cases where land claims overlap with protected areas.
From his work with Indigenous communities in Mondulkiri, Lorang said reforms can’t just stop at the law and implementation. His organization is working directly to organize 13 of Mondulkiri’s 42 communities to make a unified plea for recognition from both local and national governments.
He says he hopes these communities can work together to lobby for support from the interior and rural development ministries. “This work is very political and technical,” he said. “We need ministries to influence sub national government on it because the sub nationals don’t support [Indigenous people] and NGOs.”
In her “Letter to Greta Thunberg” series, Katie Singer explains the real ecological impacts of so many modern technologies on which the hope for a bright green (tech) future is based on.
Even when reality is harsh, I prefer it. I’d rather engineers say that my water could be off for three hours than tell me that replacing the valve will take one hour. I prefer knowing whether or not tomatoes come from genetically modified seed. If dyeing denim wreaks ecological hazards, I’d rather not keep ignorant.
The illusion that we’re doing good when we’re actually causing harm is not constructive. With reality, discovering true solutions becomes possible.
As extreme weather events (caused, at least in part, by fossil fuels’ greenhouse gas [GHG] emissions) challenge electrical infrastructures, we need due diligent evaluations that help us adapt to increasingly unpredictable situations—and drastically reduce greenhouse gas emissions and ecological damage. I have a hard time imagining a future without electricity, refrigerators, stoves, washing machines, phones and vehicles. I also know that producing and disposing of manufactured goods ravages the Earth.
Internationally, governments are investing in solar photovoltaics (PVs) because they promise less ecological impacts than other fuel sources. First, I vote for reviewing aspects of solar systems that tend to be overlooked.
Coal-fired power plants commonly provide electricity to smelt silicon for solar panels. Photo credit: Petr Štefek
Hazards of Solar Photovoltaic Power 1. Manufacturing silicon wafers for solar panels depends on fossil fuels, nuclear and/or hydro power. Neither solar nor wind energy can power a smelter, because interrupted delivery of electricity can cause explosions at the factory. Solar PV panels’ silicon wafers are “one of the most highly refined artifacts ever created.”[1] Manufacturing silicon wafers starts with mining quartz; pure carbon (i.e. petroleum coke [an oil byproduct] or charcoal from burning trees without oxygen); and harvesting hard, dense wood, then transporting these substances, often internationally, to a smelter that is kept at 3000F (1648C) for years at a time. Typically, smelters are powered by electricity generated by a combination of coal, natural gas, nuclear and hydro power. The first step in refining the quartz produces metallurgical grade silicon. Manufacturing solar-grade silicon (with only one impurity per million) requires several other energy-intensive, greenhouse gas (GHG) and toxic waste-emitting steps. [2] [3] [4]
2. Manufacturing silicon wafers generates toxic emissions In 2016, New York State’s Department of Environmental Conservation issued Globe Metallurgical Inc. a permit to release, per year: up to 250 tons of carbon monoxide, 10 tons of formaldehyde, 10 tons of hydrogen chloride, 10 tons of lead, 75,000 tons of oxides of nitrogen, 75,000 tons of particulates, 10 tons of polycyclic aromatic hydrocarbons, 40 tons of sulfur dioxide and up to 7 tons of sulfuric acid mist. To clarify, this is the permittable amount of toxins allowed annually for one metallurgical-grade silicon smelter in New York State. [5] Hazardous emissions generated by silicon manufacturing in China (the world’s leading manufacturer of solar PVs) likely has significantly less regulatory limits.
3. PV panels’ coating is toxic PV panels are coated with fluorinated polymers, a kind of Teflon. Teflon films for PV modules contain polytetrafluoroethylene (PTFE) and fluorinated ethylene (FEP). When these chemicals get into drinking water, farming water, food packaging and other common materials, people become exposed. About 97% of Americans have per- and polyfluoroalkyl substances (PFAs) in their blood. These chemicals do not break down in the environment or in the human body, and they can accumulate over time. [6] [7] While the long-term health effects of exposure to PFAs are unknown, studies submitted to the EPA by DuPont (which manufactures them) from 2006 to 2013 show that they caused tumors and reproductive problems in lab animals. Perfluorinated chemicals also increase risk of testicular and kidney cancers, ulcerative colitis (Crohn’s disease), thyroid disease, pregnancy-induced hypertension (pre-eclampsia) and elevated cholesterol. How much PTFEs are used in solar panels? How much leaks during routine operation—and when hailstorms (for example) break a panels’ glass? How much PTFE leaks from panels discarded in landfills? How little PFA is needed to impact health?
4. Manufacturing solar panels generates toxic waste. In California, between 2007 and the first half of 2011, seventeen of the state’s 44 solar-cell manufacturing facilities produced 46.5 million pounds of sludge (semi-solid waste) and contaminated water. California’s hazardous waste facilities received about 97 percent of this waste; more than 1.4 million pounds were transported to facilities in nine other states, adding to solar cells’ carbon footprint. [8]
5. Solar PV panels can disrupt aquatic insects’ reproduction. At least 300 species of aquatic insects (i.e. mayflies, caddis flies, beetles and stoneflies) typically lay their eggs on the surface of water. Birds, frogs and fish rely on these aquatic insects for food. Aquatic insects can mistake solar panels’ shiny dark surfaces for water. When they mate on panels, the insects become vulnerable to predators. When they lay their eggs on the panels’ surface, their efforts to reproduce fail. Covering panels with stripes of white tape or similar markings significantly reduces insect attraction to panels. Such markings can reduce panels’ energy collection by about 1.8 percent. Researchers also recommend not installing solar panels near bodies of water or in the desert, where water is scarce. [9]

6. Unless solar PV users have battery backup (unless they’re off-grid), utilities are obliged to provide them with on-demand power at night and on cloudy days. Most of a utility’s expenses are dedicated not to fuel, but to maintaining infrastructure—substations, power lines, transformers, meters and professional engineers who monitor voltage control and who constantly balance supply of and demand for power. [10] Excess power reserves will increase the frequency of alternating current. When the current’s frequency speeds up, a motor’s timing can be thrown off. Manufacturing systems and household electronics can have shortened life or fail catastrophically. Inadequate reserves of power can result in outages.
The utility’s generator provides a kind of buffer to its power supply and its demands. Rooftop solar systems do not have a buffer.
In California, where grid-dependent rooftop solar has proliferated, utilities sometimes pay nearby states to take their excess power in order to prevent speeding up of their systems’ frequency. [11]
Rooftop solar (and wind turbine) systems have not reduced fossil-fuel-powered utilities. In France, from 2002-2019, while electricity consumption remained stable, a strong increase in solar and wind powered energy (over 100 GW) did not reduce the capacity of power plants fueled by coal, gas, nuclear and hydro. [12]
Comparing GHG emissions generated by different fuel sources shows that solar PV is better than gas and coal, but much worse than nuclear and wind power. A solar PV system’s use of batteries increases total emissions dramatically. Compared to nuclear or fossil fuel plants, PV has little “energy return on energy Invested.” [13]
7. Going off-grid requires batteries, which are toxic. Lead-acid batteries are the least expensive option; they also have a short life and lower depth of discharge (capacity) than other options. Lead is a potent neurotoxin that causes irreparable harm to children’s brains. Internationally, because of discarded lead-acid batteries, one in three children have dangerous lead levels in their blood. [14] Lithium-ion batteries have a longer lifespan and capacity compared to lead acid batteries. However, lithium processing takes water from farmers and poisons waterways. [15] Lithium-ion batteries are expensive and toxic when discarded. Saltwater batteries do not contain heavy metals and can be recycled easily. However, they are relatively untested and not currently manufactured.
8. Huge solar arrays require huge battery electric storage systems (BESS). A $150 million battery storage system can provide 100 MW for, at most, one hour and eighteen minutes. This cannot replace large-scale delivery of electricity. Then, since BESS lithium-ion batteries must be kept cool in summer and warm in winter, they need large heating, ventilation, air conditioning (HVAC) systems. (If the Li-ion battery overheats, the results are catastrophic.) Further, like other batteries, they lose their storage capacity over time and must be replaced—resulting in more extraction, energy and water use, and toxic waste. [16]
9. Solar PV systems cannot sufficiently power energy guzzlers like data centers, access networks, smelters, factories or electric vehicle [EV] charging stations. If French drivers shifted entirely to EVs, the country’s electricity demands would double. To produce this much electricity with low-carbon emissions, new nuclear plants would be the only option. [17] In 2007, Google boldly aimed to develop renewable energy that would generate electricity more cheaply than coal-fired plants can in order to “stave off catastrophic climate change.” Google shut down this initiative in 2011 when their engineers realized that “even if Google and others had led the way toward a wholesale adaptation of renewable energy, that switch would not have resulted in significant reductions of carbon dioxide emissions…. Worldwide, there is no level of investment in renewables that could prevent global warming.” [18]
10. Solar arrays impact farming. When we cover land with solar arrays and wind turbines, we lose plants that can feed us and sequester carbon. [19]
11. Solar PV systems’ inverters “chop” current and cause “dirty” power, which can impact residents’ health. [20]
12. At the end of their usable life, PV panels are hazardous waste. The toxic chemicals in solar panels include cadmium telluride, copper indium selenide, cadmium gallium (di)selenide, copper indium gallium (di)selenide, hexafluoroethane, lead, and polyvinyl fluoride. Silicon tetrachloride, a byproduct of producing crystalline silicon, is also highly toxic. In 2016, The International Renewable Energy Agency (IRENA) estimated that the world had 250,000 metric tons of solar panel waste that year; and by 2050, the amount could reach 78 million metric tons. The Electric Power Research Institute recommends not disposing of solar panels in regular landfills: if modules break, their toxic materials could leach into soil. [21] In short, solar panels do not biodegrade and are difficult to recycle.
To make solar cells more recyclable, Belgian researchers recommend replacing silver contacts with copper ones, reducing the silicon wafers’ (and panels’) thickness, and removing lead from the panels’ electrical connections. [22]

13. Solar farms warm the Earth’s atmosphere.
Only 15% of sunlight absorbed by solar panels becomes electricity; 85% returns to the environment as heat. Re-emitted heat from large-scale solar farms affects regional and global temperatures. Scientists’ modeling shows that covering 20% of the Sahara with solar farms (to power Europe) would raise local desert temperatures by 1.5°C (2.7°F). By covering 50% of the Sahara, the desert’s temperature would increase by 2.5°C (4.5°F). Global temperatures would increase as much as 0.39°C—with polar regions warming more than the tropics, increasing loss of Arctic Sea ice. [23] As governments create “green new deals,” how should they use this modeling?
Other areas need consideration here: dust and dirt that accumulate on panels decreases their efficiency; washing them uses water that might otherwise go to farming. Further, Saharan dust, transported by wind, provides vital nutrients to the Amazon’s plants and the Atlantic Ocean. Solar farms on the Sahara could have other global consequences. [24]
14. Solar PV users may believe that they generate “zero-emitting,” “clean” power without awareness of the GHGs, extractions, smelting, chemicals and cargo shipping involved in manufacturing such systems—or the impacts of their disposal. If our only hope is to live with much less human impact to ecosystems, then how could we decrease solar PVs’ impacts? Could we stop calling solar PV power systems “green” and “carbon-neutral?” If not, why not?

New Law Would Allow Hunters Unlimited Wolf Kills, Year-Round Trapping on Private Lands
BOISE, Idaho— The Idaho House of Representatives today approved a bill allowing the state to hire private contractors to kill up to 90% of Idaho’s wolf population of approximately 1,500 wolves.
“If this horrific bill passes, Idaho could nearly wipe out its wolf population,” said Andrea Zaccardi, a senior attorney at the Center for Biological Diversity. “Unless we can stop this from becoming law, decades of progress towards wolf recovery will be lost.”
In addition to hiring private contractors to kill wolves, Senate Bill 1211 would allow hunters and trappers to kill an unlimited number of wolves, run down wolves with ATVs and snowmobiles, and trap year-round on all private land across the state. The bill will also increase annual funds for wolf killing by the Idaho Wolf Depredation Control Board from $110,000 to $300,000. Created in 2014, the Board uses taxpayer dollars and other funds to kill wolves.
Bill proponents assert that wolves kill too many elk and livestock. But wolves kill less than a fraction of 1% of Idaho’s livestock annually, and elk population numbers are above management objectives in most of the state.
As a result of today’s 58-11 approval, Gov. Brad Little must decide whether to sign the bill into law or veto it. If this bill is signed into law, the Center will be considering next steps to protect Idaho’s wolves and wildlife, which may include legal action.
“Governor Little must veto this cruel and disastrous bill,” said Zaccardi. “Idaho’s state wildlife agency should be allowed to continue to manage wolves, not anti-wolf legislators dead set on exterminating the state’s wolves. We’re going to do everything we can to fight for the survival of wolves in Idaho.”

Could we discuss silicon, that substance on which our digital world depends? [1] Silicon is a semiconductor, and tiny electronic switches called transistors are made from it. Like brain cells, transistors control the flow of information in a computer’s integrated circuits. Transistors store memory, amplify sound, transmit and receive data, run apps and much, much more.
One smartphone (call it a luxury, hand-held computer with portals to the Internet) can hold more than four billion transistors on a few tiny silicon chips, each about the size of a fingernail.
Computer chips are made from electronic-grade silicon, which can have no more than one impure atom per billion. But pure silicon is not found in nature. Producing it requires a series of steps that guzzle electricity [2] and generate greenhouse gases (GHGs) and toxic waste.
Silicon’s story is not easy to swallow. Still, if we truly aim to decrease our degradation of the Earth and GHG emissions, we cannot ignore it.
Step One
Silicon production starts with collecting and washing quartz rock (not sand), a pure carbon (usually coal, charcoal, petroleum coke, [3] or metallurgical coke) and a slow-burning wood. These three substances are transported to a facility with a submerged-arc furnace.[4]
Note that transporting the raw materials necessary for silicon production—between multiple countries, via cargo ships, trucks, trains and airplanes—uses oil and generates greenhouse gases. [5]
Step Two
Kept at 3000F (1649C) for years at a time, a submerged-arc furnace or smelter “reduces” the silicon from the quartz. During this white-hot chemical reaction, gases escape upward from the furnace. Metallurgical-grade silicon settles to the bottom, 97-99% pure—not nearly pure enough for electronics. [6]
If power to a silicon smelter is interrupted for too long, the smelter’s pot could be damaged. [7] Since solar and wind power is intermittent, they cannot power a smelter.
Typically, Step Two takes up to six metric tons of raw materials to make one metric ton (t) of silicon. A typical furnace consumes about 15 megawatt hours of electricity per metric ton (MWh/t) [8] of silicon produced, plus four MWh/t for ventilation and dust collection; and it generates tremendous amounts of CO2.[9]
Manufacturing silicon also generates toxic emissions. In 2016, New York State’s Department of Environmental Conservation issued a permit to Globe Metallurgical Inc. to release, per year: up to 250 tons of carbon monoxide, 10 tons of formaldehyde, 10 tons of hydrogen chloride, 10 tons of lead, 75,000 tons of oxides of nitrogen, 75,000 tons of particulates, 10 tons of polycyclic aromatic hydrocarbons, 40 tons of sulfur dioxide and up to 7 tons of sulfuric acid mist. [10] To clarify, this is the permittable amount of toxic waste allowed annually for one New York State metallurgical-grade silicon smelter. Hazardous waste generated by manufacturing silicon in China likely has significantly less (if any) regulatory limits.
Step Three
Step Two’s metallurgical-grade silicon is crushed and mixed with hydrogen chloride (HCL) to synthesize trichlorosilane (TCS) gas. Once purified, the TCS is sent with pure hydrogen to a bell jar reactor, where slender filaments of pure silicon have been pre-heated to about 2012F (1100C). In a vapor deposition process that takes several days, silicon gas atoms collect on glowing strands to form large polysilicon rods—kind of like growing rock candy. If power is lost during this process, fires and explosions can occur. A polysilicon plant therefore depends on more than one source of electricity—i.e. two coal-fired power plants, or a combination of coal, nuclear and hydro power. [11]
A large, modern polysilicon plant can require up to 400 megawatts of continuous power to produce up to 20,000 tons of polysilicon per year (~175 MW/hours per ton of polysilicon). [12] Per ton, this is more than ten times the energy used in Step Two—and older plants are usually less efficient. A single plant can draw as much power as an entire city of 300,000 homes.
Once cooled, the polysilicon rods are removed from the reactor, then sawed into sections or fractured into chunks. The polysilicon is etched with nitric acid and hydrofluoric acid [13] to remove surface contamination. Then, it’s bagged in a chemically clean room and shipped to a crystal grower.
Step Four
Step Three’s polysilicon chunks are re-melted to a liquid, then pulled into a single crystal of silicon to create a cylindrical ingot. Cooled, the ingot’s (contaminated) crown and tail are cut off. Making ingots often requires more electricity than smelting. [14]The silicon ingot’s remaining portion is sent to a slicer.
Step Five
Like a loaf of bread, the silicon ingot is sliced into wafers. More than 50 percent of the ingot is lost in this process. It becomes sawdust, which cannot be recycled. [15]
Step Six
Layer by layer, the silicon will be “doped” with tiny amounts of boron, gallium, phosphorus or arsenic to control its electrical properties. Dozens of layers are produced during hundreds of steps to turn each electronic-grade wafer into microprocessors, again using a great deal of energy and toxic chemicals.
Questions for a world out of balance
In 2013, manufacturers began producing more transistors than farmers grow grains of wheat or rice. [16] Now, manufacturers make 1000 times more transistors than farmers grow grains of wheat and rice combined. [17]
After I learned what it takes to produce silicon, I could hardly talk for a month. Because I depend on a computer and Internet access, I depend on silicon—and the energy-intensive, toxic waste-emitting, greenhouse gas-emitting steps required to manufacture it.
Of course, silicon is just one substance necessary for every computer. As I report in letter #3 [18], one smartphone holds more than 1000 substances, each with their own energy-intensive, GHG-emitting, toxic waste-emitting supply chain. [19] One electric vehicle can have 50-100 computers. [20] When a computer’s microprocessors are no longer useful, they cannot be recycled; they become electronic waste. [21]
Solar panels also depend on pure silicon. At the end of their lifecycle, solar panels are also hazardous waste. (In another letter, I will outline other ecological impacts of manufacturing, operating and disposing of solar PV systems.)
I’d certainly welcome solutions to silicon’s ecological impacts. Given the magnitude of the issues, I’d mistrust quick fixes. Our first step, I figure, is to ask questions. What’s it like to live near a silicon smelter? How many silicon smelters operate on our planet, and where are they? If we recognize that silicon production generates greenhouse gases and toxic emissions, can we rightly call any product that uses it “renewable,” “zero-emitting,” “green” or “carbon-neutral?”
Where do petroleum coke, other pure carbons and the wood used to smelt quartz and produce silicon come from? How/could we limit production of silicon?
How does our species’ population affect silicon’s production and consumption? I’ve just learned that if we reduced fertility rates to an average of one child per woman (voluntarily, not through coercion of any kind), the human population would start to approach two billion within four generations.[22] (At this point, we’re nearing eight billion people.) To reduce our digital footprint, should we have less children? Would we have less children?
What would our world look like if farmers grew more wheat and rice than manufacturers make transistors? Instead of a laptop, could we issue every student a raised bed with nutrient-dense soil, insulating covers and a manual for growing vegetables?
What questions do you have about silicon?
Yours,
Katie Singer
