Tropical rainforests are getting smaller. People cut down the trees to get wood. Then they sell the wood. Lots of furniture, doors, and floors are made from the wood.
Some farmers also cut down rainforest trees. They do this to keep cows on the land, or to grow coffee or sugar. Then they can sell the cows, coffee, and sugar.
Trees are good for the soil. When there are no trees, the soil is not very good.
Then new trees grow more slowly, and some trees die.
With no trees, rainforest people and animals have no homes. They can't find food, and they can't live in the rainforest.
People cut down about 20,000 square kilometers of rainforest every year. This is called deforestation.
