The rainforests of the world are a tremendous resource for many of the world's people, including Americans. Many of the things we buy at the store and use every day like fruits, vegetables, ingredients for medicines, and construction materials come from the rainforest. And scientists believe that's just the tip of the iceberg: there are many species of plants and animals in the rainforest that haven't even been discovered yet! Rainforests are disappearing at the rate of 3,800 acres a day, largely because some of the things that come from the rainforest (like lumber, oil, and gold) aren't sustainably harvested. Human and animal generations will not be able to benefit from the rainforest's future resources if this continues.
