The Amazon rainforest makes its own rain. And less forest means less precipitation. As forest destruction affects climate and vice versa, the concern is that the Amazon will be caught up in a set of feedback loops that could dramatically speed up the pace of forest loss and degradation and bring the Amazon to a point of no return. This ‘tipping point’ may occur when a certain percentage of Amazonian habitat dies, after which it will all turn into a savanna-like ecosystem.
