Greenpeace have released a publication outlining the economic exploitation issues of the Amazon rainforest and is demanding that the Brazilian government cancel hydropower projects such as the São Luiz do Tapajós (SLT) dam. This dam alone is expected to cause 2,200km2 of deforestation and to drown 400km2 of rainforest. Previous projects have led to huge habitats being wiped out causing significant impacts on the populations of fish, aquatic reptiles and the life cycles of local mammals.
