Rainforests rule! by Julie Bray. No rainforest is exactly the same. yet most rainforests are now distributed in the small land area 22.5 degrees north and 22.5 degrees south of the Equator. between the Tropic of Capricorn and the Tropic of Cancer. You can find tropical rainforests in South America and Indonesia. Other rainforests flourish further from the Equator, in Thailand and Sri Lanka. Despite occupying a relatively small area. rainforests have a colossal role to play in maintaining the world as we know it. Tropical rainforests are home to a rich, colourful variety of medicinal plants, food, birds and animals. Can you believe that a single bush in the Amazon may have more species of ants than the whole of Britain! 480 varieties of trees may be found in just one hectare of rainforest. These forests sustain around 50% of all the species on Earth. and offer a way of life to many people living in and around the forest.
