SNIP: Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response, NOAA announced today.
The global surface average for carbon dioxide (CO2), calculated from measurements collected at NOAA’s remote sampling locations, was 412.5 parts per million (ppm) in 2020, rising by 2.6 ppm during the year. The global rate of increase was the fifth-highest in NOAA’s 63-year record, following 1987, 1998, 2015 and 2016. The annual mean at NOAA’s Mauna Loa Observatory in Hawaii was 414.4 ppm during 2020.
The economic recession was estimated to have reduced carbon emissions by about 7 percent during 2020. Without the economic slowdown, the 2020 increase would have been the highest on record, according to Pieter Tans, senior scientist at NOAA’s Global Monitoring Laboratory. Since 2000, the global CO2 average has grown by 43.5 ppm, an increase of 12 percent.
The atmospheric burden of CO2 is now comparable to where it was during the Mid-Pliocene Warm Period around 3.6 million years ago, when concentrations of carbon dioxide ranged from about 380 to 450 parts per million. During that time sea level was about 78 feet higher than today, the average temperature was 7 degrees Fahrenheit higher than in pre-industrial times, and studies indicate large forests occupied areas of the Arctic that are now tundra.
Analysis of samples from 2020 also showed a significant jump in the atmospheric burden of methane, which is far less abundant but 28 times more potent than CO2 at trapping heat over a 100-year time frame. NOAA’s preliminary analysis showed the annual increase in atmospheric methane for 2020 was 14.7 parts per billion (ppb), which is the largest annual increase recorded since systematic measurements began in 1983. The global average burden of methane for December 2020, the last month for which data has been analyzed, was 1892.3 ppb. That would represent an increase of about 119 ppb, or 6 percent, since 2000.
In early April, GML typically releases a preliminary estimate of the global annual atmospheric increase for key greenhouse gases from January 1st in one year to January 1st in the next year. This preliminary estimate is based on measurements from weekly air samples collected at about 40 sites around the world. While GML’s preliminary estimates are typically a little higher than the final calculation, which incorporates additional measurements, the 2020 increase is likely to remain one of the largest in the entire record.
Should Solar Geoengineering Be a Tool to Slow Global Warming, or is Manipulating the Atmosphere Too Dangerous?

SNIP: The risks of the climate crisis are so urgent that the United States, in cooperation with other countries and under strict rules, should study the possibility of temporarily cooling the planet through solar geoengineering, a report released Thursday by the National Academies of Sciences, Engineering and Medicine says.
The report focuses on adding reflective particles to the upper atmosphere to bounce the sun’s heat back to space, brightening low-altitude clouds over the ocean to make them more reflective or thinning wispy cirrus clouds so that they trap less heat on the surface of the planet.
Supporting research into those possibilities shouldn’t be equated with actually implementing them, the NAS committee members involved with the report emphasized, adding that such studies should not detract from the need to cut greenhouse gas emissions. And scientists “need to be open to terminating” geoengineering research if findings indicate that such manipulations of the atmosphere would carry undue risk of dangerous consequences, they said.
“It’s kind of surreal to even be talking about this,” said Ambuj Sagar, who studies science and technology policy at the Indian Institute of Technology, Delhi, and was part of the committee that compiled the report. “You can’t be doing climate policy without thinking about geoengineering, and the more you get into it, the more complex it is. It raises all kinds of issues with international politics and governance.”
The Academies’ report recommends a research budget of $100 million to $200 million for the next five years, as a “minor part of the overall U.S. research portfolio related to climate change.” For now, it says, research should not be focused on a path toward deployment, but on understanding how solar geoengineering fits with all the options for responding to climate change.
Solar geoengineering only makes sense in tandem with cutting emissions, because solar geoengineering doesn’t actually address the buildup of greenhouse gases that warms the climate. It only masks some of the symptoms for as long as the measures are active. Temperatures would rebound dangerously fast when atmospheric manipulation ends. A 2015 report from the Academies concluded that geoengineering is no substitute for emissions reductions, and that none of the proposed interventions are ready for deployment.
The topic of geoengineering has surfaced with increasing frequency in recent years. A few months ago, scientists with the National Oceanic and Atmospheric Administration said their latest budget included $4 million to study what they called a “Plan B” for climate change. In 2013, NBC and others reported that U.S. intelligence agencies helped fund a previous National Academy of Sciences study assessing geoengineering risks.
Most recently, an experiment called SCoPEx, led by the Keutsch Group at Harvard and planned for June in the sky above Sweden, has been portrayed both as a crucial step toward better understanding solar geoengineering, or as a dangerous slip down a slope leading to a potential Icarus moment for humanity, with the illusion of control over nature ending in a fiery crash.
The first step of SCoPEx is to launch a balloon to test instruments that could be used to measure how reflective particles work in a small area and affect the adjacent atmosphere.
Even that small step is worrisome, said Linda Schneider, of the Heinrich Böll Foundation, a nonprofit group with ties to the German Green Party.
“What civil society currently is worried about is that the new NAS report will be used to legitimize Harvard’s SCoPEx project,” she said. “It’s notable how the first thing they highlight is the need for a massive expansion of research. We maintain that it is an untestable technology and the real impacts and consequences would only be felt once the technology would actually be deployed, and then there is no going back.”
[Ed Note: Studying geo-engineering legitimizes it and makes it a possibility in people’s minds. We all know that if it worked to reduce global temperatures, those in power and the oil companies would use it as an excuse to keep destroying the planet with industrialism and fossil fuels. The whole idea is psychotic and is a moral hazard: time spent researching geo-engineering should instead be spent figuring out a humane path for ending industrial civilization.]

SNIP: The storage potential of one of the Earth’s biggest carbon sinks – soils – may have been overestimated, research shows. This could mean ecosystems on land soaking up less of humanity’s emissions than expected, and more rapid global heating.
Soils and the plants that grow in them absorb about a third of the carbon emissions that drive the climate crisis, partly limiting the impact of fossil-fuel burning. Rising carbon dioxide levels in the atmosphere can increase plant growth and, until now, it was assumed carbon storage in soils would increase too.
But the study, based on over 100 experiments, found the opposite. When plant growth increases, soil carbon does not. The finding is significant because the amount of organic carbon stored in soils is about three times that in living plants and double that in the atmosphere. Soils can also store carbon for centuries, whereas plants and trees rot quickly after they die.
It is not yet known how big the effect of lower carbon storage in soils might be on the speed of climate change, and experts cautioned that other impacts of the climate emergency such as drought would also affect how well plants and soils store carbon.
“We found that when rising CO2 increases plant growth, there is a decrease in soil carbon storage. That’s a very important conclusion,” said César Terrer, who led the research while at Stanford University in the US. He said that if soils do absorb less in future, “the speed of global warming could be higher”.
The study, published in the journal Nature, analysed more than 100 experiments from across the world in which soils, plants and trees were exposed to higher CO2 levels than in today’s atmosphere. The biomass growing in forests rose by 23% in experiments where the CO2 level used was double pre-industrial atmospheric levels. It is 50% higher today. But the forest soils did not store any more organic carbon at all.
It was thought that biomass and soil carbon would increase in tandem, as more plant biomass falls to the ground and turns into organic matter. But increased plant and tree growth requires more nutrients from the soil, which may explain the new finding, the scientists said. Extracting the extra nutrients requires the plants to increase the symbiotic microbial activity in their roots, which then releases CO2 to the atmosphere that might otherwise have remained locked in the soil.

SNIP: Fishing boats that trawl the ocean floor release as much carbon dioxide as the entire aviation industry, according to a groundbreaking study.
Bottom trawling, a widespread practice in which heavy nets are dragged along the seabed, pumps out 1 gigaton of carbon every year, says the study written by 26 marine biologists, climate experts and economists and published in Nature on Wednesday.
The carbon is released from the seabed sediment into the water, and can increase ocean acidification, as well as adversely affecting productivity and biodiversity, the study said. Marine sediments are the largest pool of carbon storage in the world.
The report – Protecting the global ocean for biodiversity, food and climate – is the first study to show the climate impacts of trawling globally. It also provides a blueprint outlining which areas of the ocean should be protected to safeguard marine life, boost seafood production and reduce climate emissions.
Only 7% of the ocean is under some kind of protection.
The top 10 countries with the most carbon emissions from bottom trawling, and therefore the most to gain, were China, Russia, Italy, UK, Denmark, France, the Netherlands, Norway, Croatia and Spain.

SNIP: When an oil or gas well reaches the end of its lifespan, it must be plugged. If it isn’t, the well might leak toxic chemicals into groundwater and spew methane, carbon dioxide and other pollutants into the atmosphere for years on end.
But plugging a well is no simple task: Cement must be pumped down into it to block the opening, and the tubes connecting it to tanks or pipelines must be removed, along with all the other onsite equipment. Then the top of the well has to be chopped off near the surface and plugged again, and the area around the rig must be cleaned up.
There are nearly 60,000 unplugged wells in Colorado in need of this treatment — each costing $140,000 on average, according to the Carbon Tracker, a climate think tank, in a new report that analyzes oil and gas permitting data. Plugging this many wells will cost a lot — more than $8 billion, the report found.
The first western oil well broke ground in Colorado in 1860. Drilling has been an important part of the state’s economy ever since; as of 2019, Colorado ranked in the sixth and seventh in the nation for oil and natural gas production, respectively.
When it comes to cleanup, Colorado uses a tiered system known as blanket bonding. Small operators can pay ahead with bonds on single wells. Drillers with more than 100 wells statewide pay a fixed reclamation fee of $100,000, regardless of the number of wells. A similar system also applies to wells on federal public land in the state. Large companies pay a single $150,000 bond, which covers unlimited federal public land wells throughout the country. There are about 7,400 public-land wells capable of producing oil or gas in Colorado, according to the Bureau of Land Management.
When a driller walks away or cannot pay for cleanup, the well enters the state’s Orphan Well Program, which works to identify and plug these wells. There are about 200 wells in the program right now, according to the state. But a closer look at state data reveals a large number of wells at risk.
There are also inactive wells: Nearly 10% of the state’s wells have not produced oil or gas in at least two years, according to a Carbon Tracker analysis of state permitting data. Unlike some of the neighboring oil states, Colorado requires that companies pay a single bond on each inactive well of this sort. This costs either $10,000 or $20,000, depending on the depth of the well. In theory, these payments protect the state, in case the well owner goes bankrupt. But in Colorado, it’s still far cheaper for energy companies to pay the cost of that single, unused well — and the small annual premium payments on the bond — than to actually plug it. “Colorado clearly makes it cheaper to idle a well than to clean it up,” Williams-Derry said.
In Colorado, just two companies are responsible for nearly 70% of the bonds for currently inactive wells. One is Noble Energy Inc., which was purchased by the global oil giant Chevron in October 2020. The other is Kerr-McGee, a subsidiary of Occidental Petroleum. Kerr-McGee was responsible for the 2017 home explosion in Firestone, Colorado, that killed two people. Last year, the COGCC fined the company more than $18 million for the accident, by far the largest fine in state history. Both companies still own large numbers of wells in the Denver-Julesburg Basin, the prolific oil and gas formation beneath central and eastern Colorado. And the mass desertion of wells is not hypothetical: In fall of 2019, a small company called Petroshare Corporation went bankrupt and left about 90 wells for the state to cleanup. That alone will cost Colorado millions of dollars. Last summer, when California’s largest oil driller filed for Chapter 11 bankruptcy protection, it left billions in debt and more than 17,000 unplugged wells.
Disposable plastic face masks pose huge environmental risks, with 3 million used a minute, researchers warn
SOURCE: The Independent
DATE: March 11, 2021
SNIP: The huge demand for face masks in the year since the coronavirus pandemic has swept the globe has resulted in enormous production of disposable masks, but it is now feared that undisposed of properly, they pose a major threat to the natural world.
Recent studies estimate around the world humans are now using a mind-boggling 129 billion face masks every month. Taking 31 days in a month that is an average usage of 2.8 million masks a minute being used across the planet.
Researchers now warn the huge volume of mask, with their plastic composition, pose a growing environmental threat and are urging action to prevent it from becoming the next plastic problem.
Environmental toxicologist Elvis Genbo Xu from the University of Southern Denmark and professor Zhiyong Jason Ren, an expert in civil and environmental engineering at Princeton University, said: “Disposable masks are plastic products, that cannot be readily biodegraded but may fragment into smaller plastic particles, namely micro- and nanoplastics that widespread in ecosystems.
“The enormous production of disposable masks is on a similar scale as plastic bottles, which is estimated to be 43 billion per month.”
If not disposed of for recycling, like other plastic waste, disposable masks can end up in the environment, freshwater systems, and oceans, where weathering can generate a large number of micro-sized particles (smaller than 5mm) in a matter of weeks and further fragment into nanoplastics (smaller than 1 micrometer).
The researchers stressed they do not know exactly how masks contribute to the large number of plastic particles detected in the environment – simply because no data on mask degradation in nature exists.
“But we know that, like other plastic debris, disposable masks may also accumulate and release harmful chemical and biological substances, such as bisphenol A, heavy metals, as well as pathogenic micro-organisms,” said Dr Genbo Xu.
“These may pose indirect adverse impacts on plants, animals and humans.”

SNIP: Energy companies are preparing to destroy nearly 16 square miles of intact desert wildlands in southern Nevada – an area equivalent to 70% of Manhattan or 28 times the size of the UNLV campus – for two solar projects outside of Las Vegas. Companies are setting up fencing and construction markers at the Gemini Solar project northeast of Las Vegas, and at the Yellow Pine Solar site south of Pahrump; crews will finish mowing and bulldozing these lands in a matter of months.
This habitat loss will continue a trend of severe fragmentation by energy and urban sprawl that threatens the viability and resilience of numerous wildlife species across the Mojave, and compounds the pressure wildlife face from climate change. Southern Nevada has already lost nearly 20 square miles to utility-scale solar development. The Gemini and Yellow Pine solar projects are the latest, but not the last massive projects proposed on public lands here. The proposed Battle Born Solar project would carve up another 14 square miles of habitat northeast of Las Vegas, if approved. Energy companies have submitted proposals for several other projects in the region in response to the states renewable portfolio standard. Throw in plans for expanded lithium mining to feed our battery storage demand, and the toll on Nevada wildlands grows further.
This is not the first time a renewable energy rush has threatened ecosystems in the southwest, but Nevada has resisted policy solutions that are known to reduce pressures on wildlands. A lack of of science-based land management planning, as well as a state capital that is allergic to distributed generation policies has allowed utility companies and energy project developers to select sites with little concern for impacts on wildlife. The Gemini Solar project, for example, is expected to destroy 25% of the remaining habitat of the imperiled threecorner milkvetch on public lands. The Gemini project will also mow down land previously identified by the Fish and Wildlife Service as a priority habitat linkage for the desert tortoise; biologists have been sounding the alarm that the tortoise population continues to spiral downward as a result of multiple factors, to include habitat loss.
Despite this astonishingly fast pace of habitat destruction for energy sprawl, there is very little overt pressure on Federal and State-level authorities to address the issue. A review of press releases over the past two years from national environmental organizations active in Nevada reveals no mention of the Yellow Pine or Gemini Solar projects.

SNIP: In the tenth century, Erik the Red, a Viking from Iceland, was so impressed with the vegetation on another Arctic island he had found he called it “the green land.” Today, it’s Greenland’s rocks that are attracting outsiders – superpowers riding a green revolution.
The world’s biggest island has huge resources of metals known as ‘rare earths,’ used to create compact, super-strong magnets which help power equipment such as wind turbines, electric vehicles, combat aircraft and weapons systems.
The metals are abundant globally, but processing them is difficult and dirty – so much so that the United States, which used to dominate production, surrendered that position to China about 20 years ago.
As Greenland’s ice sheet and glaciers recede, two Australia-based mining companies – one seeking funding in the United States, the other part-owned by a Chinese state-backed firm – are racing for approval to dig into what the U.S. Geological Survey (USGS) calls the world’s biggest undeveloped deposits of rare earth metals.
The contest underscores the polluting side of clean energy, as well as how hard it is for the West to break free of China in production of a vital resource. Rare earth metals have many uses, and last year China produced about 90% of them, according to Toronto-based consultancy Adamas Intelligence. As U.S.-China tensions mount, President Joe Biden’s administration said last month it will review key U.S. supplies, including rare earths, to ensure other countries cannot weaponise them against the United States.
Each Greenland mine would cost about $500 million to develop, the companies say. Both plan to send mined material away for final processing, an activity that is heavily concentrated in China. The only rare earth mine now operating in the United States – Mountain Pass in California – is partly owned by a Chinese state-backed company that currently sends material mined in the U.S. to China for processing.
The Greenland sites are less than 16 km (10 miles) from each other at the southern tip of the island, near a UNESCO World Heritage Site. Debate on them has triggered a political crisis in the capital of Nuuk, forcing a general election on the island of 56,000, due in April. Many Greenlanders, while concerned about pollution, feel mining is key to develop their fragile economy. In a 2013 poll, just over half said they want raw materials to become the country’s main source of income.
The country may ultimately back either project, both, or neither, but for those Greenlanders open to mining, the two proposals boil down to a choice between one mine that would not produce radioactive material, and another that would.
The first mine, a private initiative from an Australian geologist who has presented it to U.S. officials, would not involve nuclear material. It has won preliminary environmental approval, but it needs cash and a processing plan.
The second one has already spent more than $100 million preparing to mine, has proven processing technology through its Chinese partner, and won initial political support from Greenland’s coalition government. But its plans include exporting uranium, a nuclear fuel, and it recently ran into strong opposition, including from residents of the nearby town of Narsaq.
“As indigenous people we have lived in harmony with nature for many, many years,” said Mariane Paviasen, an opposition lawmaker who lives in the town. “We use these lands to hunt and fish.”
Greenland’s rare earth metals are also a chance for America and Europe to regain control of a strategic resource.
The island’s potential as a source of the raw materials needed for renewable energy technologies gained momentum in 2010, when China threatened to cut off its supply of rare earth metals to Japan, and tightened quotas to international buyers.
Prices for some of the metals have jumped in recent months, driven by surging demand for electric vehicles as well as concerns that Beijing may restrict sales.
Greenland’s position near the eastern flank of the United States makes it a sensitive location. Former U.S. President Donald Trump offered to buy the island in 2019, and he was not the first U.S. president to do so: In 1946 Harry S. Truman offered Denmark $100 million for it. A defence treaty between Denmark and the United States dating back to 1951 gives the U.S. military almost unlimited rights there, and Greenland houses the northernmost U.S. military base.
The only major plant outside China that does the complex work of separating individual rare earth elements is in Malaysia. But others – including the Mountain Pass mine in the United States – are planning or have started to build such facilities.
“For the foreseeable future, China is going to be the major player in all of these supply chains simply because it’s so far advanced and because it’s not stopping and waiting for alternatives to catch up,” said Ryan Castilloux, head of Adamas.
Tanbreez says half the rare earth metals it mines would be lanthanum and cerium – relatively plentiful metals used in telescope lenses and auto catalysts to cut emissions. About a fifth would be yttrium, which is in demand for lasers and the superconductors used in quantum computing.
Neither of the Greenland projects would be pollution-free. Both plan for mined rock to be locally crushed and separated into concentrates to send for final processing.
Tanbreez’s mining waste will be piped to a lake which, while it does not contain fish, feeds a river with a large population of Arctic char. Turbid water could impact the char, according to the company’s environmental report, which says it plans to dump some 550 tonnes a day of waste material into the lake and will dam it to prevent disruption downstream.
Tanbreez’s plan has passed the public consultations stage and received a government permit in September. Now the company is working on parliament approval.
The rival mountaintop site not far from Tanbreez is called Kvanefjeld, or Kuannersuit in Greenlandic. For John Mair, managing director of its owner, Greenland Minerals Ltd, it’s a world-class opportunity at the right moment.
Kvanefjeld’s main offer is neodymium, needed for wind turbines. Brussels says the EU’s demand for the metal may reach 13,000 tonnes per year by 2050, three times more than it used in 2015. Neodymium is also used in combat aircraft.
Greenland Minerals, which bought its concession from Barnes, says its planned mine will, at least initially, send minerals it produces to China for final processing. It says it plans to find a site in Europe, but has not said when.
But Greenland Minerals faces public opposition. It is one step behind Tanbreez in the environmental vetting process – and its ores include significant amounts of radioactive materials.
When Greenland Minerals embarked on public consultations this year, protests erupted. At one meeting in Narsaq on Feb. 10, locals both inside and outside the hall banged windows and played loud music to disrupt presentations.
As opposition mounted, a small pro-mining party, Demokraatit, triggered a general election by pulling out of Greenland’s coalition in early February.
Polls suggest Greenland’s main opposition party, Inuit Ataqatigiit (IA), which has a zero-tolerance policy for uranium, will become the biggest in parliament, so would be first to try to form a new coalition.
“Our aim,” IA lawmaker and Narsaq resident Paviasen told Reuters, “is to halt the (Kvanefjeld) mining project.” But IA says it has not expressed opposition to Tanbreez, which is seen as less of a threat to the environment.
Kvanefjeld would dump much more waste than Tanbreez – about 8,500 tonnes each day – into a lake on top of the mountain, the Greenland Minerals plan says.
Greenland Minerals says any increase in background radiation from its Kvanefjeld mine will be minimal. It plans to build a concrete 45-meter dam to contain the radioactive waste and to spray water on the ground to keep the dust from blowing away.
The dam will be built to international standards to “withstand even the worst imaginable seismic activity,” it said in a report submitted to Greenland’s government last year.
Even so, residents say they worry contaminated water will seep into nearby rivers or that the dam will fail entirely. They cite the collapse of a mining dam in Brazil two years ago that killed 270 people.
As the crisis has deepened, Greenland Minerals’ shares have dropped by more than 50%. If the mine goes ahead, Paviasen says, many people plan to move away.

SNIP: A large iceberg about 20 times the size of Manhattan broke off the Brunt Ice Shelf in the Weddell Sea section of Antarctica during the past day, following the buildup of a large crack in the floating ice during the past decade. The iceberg is about 490 square miles and about 492 feet thick, according to the British Antarctic Survey (BAS).
The iceberg is large, but not as huge as the iceberg that calved from the Larsen C Ice Shelf in 2017 and recently threatened to run aground on South Georgia Island.
The BAS maintains a research station on the ice shelf, known as the Halley Research Station, but it will be unaffected by this calving event, the organization said. In 2016, the BAS moved the station, which was built on skis, to protect it from spreading cracks that could’ve left it marooned, floating out to sea aboard an iceberg.
The past decade has seen three major cracks develop through the floating ice shelf, according to a BAS news release.
Ice shelves are floating areas of ice that help hold back ice anchored on land. Because they’re already displacing water, the calving event will not raise sea levels, but icebergs are carefully monitored in case they move into shipping lanes.
Adrian Luckman, a researcher at Swansea University, has closely tracked satellite images of Brunt as the cracks have progressed.
“Although the breaking off of large parts of Antarctic ice shelves is an entirely normal part of how they work, large calving events such as the one detected at the Brunt Ice Shelf on Friday remain quite rare and exciting,” he told the BBC.
Calving events can act to speed up the movement of inland ice into the sea, though it’s not clear that’s the case with the Brunt Ice Shelf in particular. Such movement would add to sea level rise, and there are growing concerns about the potentially unstoppable melting of the West Antarctic Ice Sheet from warming waters that are weakening ice shelves and penetrating the base of inland glaciers.

SNIP: Parts of Brazil’s Amazon rainforest are being illegally sold on Facebook, the BBC has discovered.
The protected areas include national forests and land reserved for indigenous peoples.
Some of the plots listed via Facebook’s classified ads service are as large as 1,000 football pitches.
“The land invaders feel very empowered to the point that they are not ashamed of going on Facebook to make illegal land deals,” said Ivaneide Bandeira, head of environmental NGO Kanindé. [C]ampaigners have claimed the country’s government is unwilling to halt the sales.
Anyone can find the illegally invaded plots by typing the Portuguese equivalents for search terms like “forest”, “native jungle” and “timber” into Facebook Marketplace’s search tool, and picking one of the Amazonian states as the location.
Some of the listings feature satellite images and GPS co-ordinates.
Many of the sellers openly admit they do not have a land title, the only document which proves ownership of land under Brazilian law.
The illegal activity is being fuelled by Brazil’s cattle ranching industry.
Deforestation in the Brazilian Amazon is at a 10-year high, and Facebook’s Marketplace has become a go-to site for sellers like Fabricio Guimarães, who was filmed by a hidden camera.
“There’s no risk of an inspection by state agents here,” he said as he walked through a patch of rainforest he had burnt to the ground.
With the land illegally cleared and ready for farming, he had tripled his initial asking price to $35,000 (£25,000).
Fabricio is not a farmer. He has steady middle-class job in a city, and views the rainforest as being an investment opportunity.
The BBC later contacted Fabricio for his response to its investigation but he declined to comment.
One man, called Alvim Souza Alves, was trying to sell a plot inside the Uru Eu Wau Wau indigenous reserve for about £16,400 in local currency.
It is the home to a community of more than 200 Uru Eu Wau Wau people. And at least five further groups that have had no contact with the outside world also live there, according to the Brazilian government.
The BBC showed the Facebook ad to community leader Bitaté Uru Eu Wau Wau.
He said the lot was in an area used by his community to hunt, fish and collect fruits.
“This is a lack of respect,” he said.
“I don’t know these people. I think their objective is to deforest the indigenous land, to deforest what is standing. To deforest our lives, you could say.”
He said the authorities should intervene, and also urged Facebook – “the most accessed social media platform” – to take action of its own.
A common strategy is to deforest the land and then plead with politicians to abolish its protected status, on the basis it no longer serves its original purpose.
The land grabbers can then officially buy the plots from the government, thereby legalising their claims.
For its part, Facebook claims trying to deduce which sales are illegal would be too complex a task for it to carry out itself, and should be left to the local judiciary and other authorities. And it does not appear to see the issue as being serious enough to warrant halting all Marketplace land sales across the Amazon.
Ivaneide Bandeira, who has been trying to combat deforestation in the state of Rondônia for 30 years, said she was losing hope.
“I think this is a very hard battle. It is really painful to see the forest being destroyed and shrinking more and more,” she said.
“Never, in any other moment in history, has it been so hard to keep the forest standing.”
