There are three major rainforests in the world: the Amazon, Congo, and Indonesia rainforests. The Amazon is the largest rainforest containing about 390 billion trees. Rainforests are full of beautiful and exotic animals and provide 50% of the world's food and 3/4 of clean water. Indigenous people of the Amazon live in houses made of leaves and straw, with fathers farming/hunting and mothers gardening/cooking, while children learn about plants and animals through play. Threats to the rainforest include deforestation for wood and paper, but conservation efforts like providing technology to report illegal logging are helping to protect these vital ecosystems.
