Today, the Chief of the Paiter Surui indigenous people in the state of Rondônia, Brazil has issued the following plea for help to stop illegal logging and mining on their lands. The letter is unedited.
It's not that Dilma Rousseff, Brazil's ousted President, was wonderful for the environment, writes Ed Atkins. It's that Michel Temer's new regime is certain to be far worse. Plans are afoot to weaken environmental assessments for large projects like mines, roads and dams. And the new Minister of Agriculture is a notorious campaigner for hugely increased deforestation.
In the thick of the Olympic frenzy, one voice that was systematically excluded from mainstream narratives is that of Brazil's Indigenous Peoples, writes Lewis Evans, who have fought to survive through centuries of dehumanisation, theft and genocide. And now they face a fresh attack as a proposed constitutional change, PEC 215, threatens a new round of indigenous land theft.
Brazil's new neoliberal government is intent on building a massive new dam deep in the Amazon rainforest on the on the Tapajós river, writes Helle Abelvik-Lawson, obliterating the indigenous territory of the Munduruku people in defiance of their constitutional rights.
Land theft, agribusiness and violence pose an existential threat to Brazil's Guarani people, writes Lewis Evans. They maintain a powerful resolve to regain their historic lands, and even have the law on their side - but the tribe will need international support to prevail against murderous ranchers and farmers, corrupt politicians and a paralysed legal system.
A constitutional amendment that would allow 'strategic' public works including dams, roads, mines and other mega-projects to go ahead following the mere completion of an environmental impact assessment is being considered by a Committee of the Brazilian Senate, writes Helle Abelvik-Lawson.
Amidst the turmoil of the presidential impeachment, writes Jan Rocha, right wing members of Brazil's Congress are set to pass new laws that would build new roads across the Amazon, open up indigenous reserves to industrial exploitation, and create a surge in carbon emissions from burning forests.
Disregarding revelations of systemic political corruption in Brazil's hydropower sector, President Dilma Rousseff is ploughing ahead with a cascade of giant dams on the mighty Tapajos river. Among the companies touting to win huge construction contracts are France's EDF and Engie, and Germany's Voith and Siemens - in a consortium led by Brazil's Electrobras, which stands accused of high-level corruption over four other dam projects.
Those who dare suggest that pesticides might be implicated in Brazil's microcephaly outbreak are being furiously attacked as irrational, nonsense-spouting 'conspiracy theorists', writes Claire Robinson. But the attackers have an uncanny ability to get their own facts in a twist. And among them are writers linked to industries with huge economic interests in the matter.
With the proposed connection between the Zika virus and Brazil's outbreak of microcephaly in new born babies looking increasingly tenuous, Latin American doctors are proposing another possible cause: Pyriproxyfen, a pesticide used in Brazil since 2014 to arrest the development of mosquito larvae in drinking water tanks. Might the 'cure' in fact be the poison?
The Aedes mosquitos that carry the Zika virus and dengue fever are not just perfectly adapted to life in cities, writes Nadia Pontes. They are also being helped along by warming climates which increase their range. It's time to get serious about the health implications of a hotter planet.
The Kawahiva, an uncontacted tribe in the Amazon rainforest, face extinction unless Brazil's government acts to secure their legal rights to land, security and to remain undisturbed by outsiders, writes Lewis Evans. The decree that would achieve this vital goal has been sitting on the Minister of Justice's desk since 2013. Let's make sure he signs it soon, before it's too late.
Roads, mines, dams, power lines, pipelines and other infrastructure projects are fast eating into the world's 'core forests', writes Bill Laurance. These rare and precious places where wildlife and ecological processes can flourish undisturbed must come before the evanescent gains of 'development'. To save what's left, governments and funders must learn the word 'No!'
In Brazil's microcephaly epidemic, one vital question remains unanswered: how did the Zika virus suddenly learn how to disrupt the development of human embryos? The answer may lie in a sequence of 'jumping DNA' used to engineer the virus's mosquito vector - and released into the wild four years ago in the precise area of Brazil where the microcephaly crisis is most acute.
Never mind Brazil's COP21 promises to cut its carbon emissions, writes Jan Rocha. New laws passing through Congress will encourage deforestation by removing safeguards and opening up indigenous territories to mega-projects. Serious drought is already contributing to a big increase in forest fires.
It's not just Indonesia's forests and peatlands that are burning - the Amazon is suffering almost as badly, with over 18,000 fires last month in Brazil alone, write Jos Barlow & Erika Berenguer. The future is looking hot and fiery.
Brazil has suffered its biggest ever industrial disaster, write Ana Luisa Naghettini & Geraldo Lopes. Breached and overflowing dams have released a massive slug of toxic muds and tailings from iron mining into the country's fifth largest river system that provides drinking water for downstream cities, destroying ecosystems in rivers and vast areas of biologically fragile ocean.
Deep in the Brazilian Amazon indigenous people have been protecting their reserve from illegal loggers, writes Luana Lila. The loggers took their revenge by kindling one of the Amazon's biggest fires ever, destroying almost 200,000 hectares of rainforest.
Brazil is about to auction hundreds of fracking blocks across the country - extending deep into the Amazon forest including the territories of remote and vulnerable indigenous peoples. Registered bidders include BP, Shell and ExxonMobil.
Guarani man Semião Vilhalva was murdered by ranchers' gunmen last weekend after his community reoccupied parts of their ancestral land from ranchers. Thousands of Guarani Indians holding on to tiny patches of their ancestral land are living in constant fear of forcible eviction.
Jairo Restrepo is a leading champion of organic farming in Brazil, writes JuanFran Lopez, and now his influence has spread across the world. His mission too has expanded to include campaigning for the rights of small scale farmers, and an even wider project of economic, technological and societal transformation to put people at the centre of political power.
Last December Brazil's indigenous Peoples defeated the PEC 215 constitutional amendment that was meant to open up their territories for agribusiness, mining, power generation and industry, writes Chris Lang. But now, thanks to 'Chainsaw Queen' Kátia Abreu, minster of agriculture, it's back on the agenda ... and resistance is growing once again.
After four years of low rainfall Brazil's commercial capital, Sao Paulo, is suffering from a grim combination of high temperatures and water shortages, writes Leila Carvalho. And now the drought has given rise to a lethal plague of dengue fever.
A proposed $30 billion railway line linking the the Peruvian and Brazilian coasts threatens devastation to forests and indigenous tribes that lie along its route, and will add to wider pressures on land and forests.
