Eco-friendly rocker Sting is urging the Brazilian government to rethink plans to build a new hydro-electric dam in the Amazon rainforest.
The former Police frontman has flown to the country to address the proposals for the megastructure, known as the Belo Monte project, which will be the third largest dam of its kind in the world.
Sting is adamant the project, which will flood large areas of the region, will have a damaging affect on the Amazon's indigenous population, as well as destroying the habitat of many rare animals.
Speaking at a press conference in Sao Paulo, the star teamed up with indigenous leader Raoni Metyktire to urge Brazilian politicians to reconsider their plans.
Sting says, "This is the heart of the Amazon and what happens here affects the whole world. This was my intuition but now the science is backing that up, I mean substantial science is saying this is true. We need to save this forest.
"It is the biggest contribution to greenhouse gases - deforestation. Way beyond industrial pollution, way beyond the burning of fossil fuel for transport, or heating. We are looking to Brazil for leadership here.
"I can't pretend to be an expert on hydro-electric power - that is ridiculous. At the same time I want all the arguments for and against to be heard. This is my only concern - then it is up to the Brazilian people."
Sting previously campaigned alongside Metyktire 20 years ago as they fought to oppose to a hydro-electric project on the Amazon's Xingu River.
