The Amazon rainforest contains almost two years of global carbon emissions, but is under threat as a carbon sink, according to a new study.

Deforestation in Brazil's Amazon rainforest dropped 33.6% in the first six months of President Luiz Inácio Lula da Silva’s term, providing an encouraging sign for his administration's environmental efforts.

Brazil already receives money from wealthy nations, namely Germany and Norway, to fight deforestation in the Amazon rainforest. Norway alone has donated $1.2 billion to Brazils Amazon Fund since its creation in 2008. However, both European nations suspended contributions last year, citing continued deforestation and questioning whether the government wants to stop it.
