1. Where are the rainforests? Rainforests cover six per cent of the Earth’s surface. There are rainforests in many parts of the world but the biggest forests are in South America, Africa and South East Asia. There aren’t any rainforests in Europe or North America. 2. What’s in the rainforests? About 75% of all the types of animals that we know come from rainforests. Thousands and thousands of animals live in rainforests.
