Satellite photos show Amazon vanishing
Clear-cutting for roads and agriculture has transformed the Amazon rain forest in western Brazil, as a new set of satellite images from NASA illustrates.
As Amazon’s ‘extinction debt’ piles, species will pay the price
Species will continue to go extinct more than 3 decades after deforestation in the Amazon has stopped, if key forest areas are not restored.
