The heart of the Amazon rainforest is at risk. There are dangerous plans to build a new mega-dam across one of the Amazon's largest rivers - the Tapajos. If it goes ahead, the dam threatens to destroy Indigenous People's homes and the unique biodiversity of the area.
But one Indigenous community, the Munduruku, are fighting back, and they need our support. The Munduruku are demanding that the Brazilian government officially recognise their ancestral land so they can keep the companies behind the mega-dam out.
If thousands of us around the world take a stand with the Munduruku, we can send a clear message - the Brazilian government must protect the heart of the Amazon.
Hydro-dams may seem like a clean energy solution but they are far from it. The companies desperate to help build the São Luiz do Tapajós mega-dam, like Siemens and General Electric, stand to profit a great deal at the expense of the environment. Building this mega-dam would flood hundreds of kilometers of rainforest creating a reservoir the size of New York City. The flooded forest would release the huge amounts of carbon and methane it once stored into the atmosphere, contributing further to greenhouse gas emissions.
The dam could also wreak havoc on the feeding and breeding grounds of river dolphins, turtles, fish and other species living in the river, and could even lead to extinction for some. And on land, a whole host of rare plants and endangered animal habitat, newly discovered mammals, as well as villages and communities would be drowned and gone forever.
So far from being the clean energy solution the companies behind the dam would have us believe, destructive dams in fragile ecosystems like the Amazon come with a whole host of tragic environmental and social impacts.
Frequent and severe droughts in Brazil mean the production capacity of dams have already been called into question. Similar dams, like the Belo Monte dam, have also recently been linked to corruption and therefore threaten the reputations of the companies involved in building them.
