Deforestation is having a more devastating effect on the Amazon rainforest than earlier data suggested. While cutting down large swaths of trees destroys vital habitats, it also harms the region's ability to generate its own rainfall. According to a new study published in the journal Nature, the Amazon could reach a tipping point and experience major forest dieback (where large areas of the rainforest dry out and turn into a savanna) sooner than previously thought.
