Rainforests
Rainforests are forests characterized by high rainfall, with annual rainfall in the case of tropical rainforests between 250 and 450 centimetres (98 and 177 in),[1] and definitions varying by region for temperate rainforests. The monsoon trough, plays a significant role in creating the climatic conditions necessary for the Earth's tropical rainforests. Five million years from now, the Amazon rainforest may long since have dried and transformed itself into savannah, killing itself in the progress. The descendants of our known animals may adapt to the dry savannah of the former Amazonian rainforest and thrive in the new, warmer temperatures.
