The document discusses key facts about tropical rainforests. It notes that rainforests cover only 6% of the planet's surface but contain over half of all plant and animal species. The largest rainforest, the Amazon, spans 2.5 million square miles across South America and produces over 20% of the world's oxygen. Rainforests exist near the equator in a band around the globe, where temperatures remain warm year-round without freezing. Over 30 million species of plants and animals, including toucans, jaguars, monkeys, frogs, gorillas, tigers, and gibbons, live together in the dense environments of the rainforest.
