1 . Tropical rainforests (热带雨林) are home to native peoples who rely on their surroundings for food, shelter, and medicines. Today very few forest people in many areas like the Philippines, Papua New Guinea live in traditional ways; most have been displaced by outside settlers or have been forced to give up their lifestyles by governments.

Of the remaining forest people, the Amazon supports the largest native or native populations, although these people, too, have been affected by the modern world. While they still depend on the forest for traditional hunting and gathering, most Amerindians, as American native people are called, grow crops, use western goods, and make regular trips to towns and cities to bring foods and products to market. In Africa there are native forest people sometimes known as pygmies. The tallest of these people, also called the Mbuti, are not more than 5 feet in height. Their small size enables them to move about the forest more quickly than taller people.

Tropical rainforests have supported humans since ancient times. Although forest life cannot be described as easy, these peoples have built their lives around the surrounding forest and its systems. Still, these forest people can teach us a lot about the rainforest. Their knowledge of medicinal plants used for treating illness is valuable, and they have a great understanding of the ecology (生态学) of the Amazon rainforest. As a result, they are a great storehouse of the knowledge about the forest. They know the medicinal functions of plants and understand the value of the forest as an undamaged ecosystem. As forests fall, these native peoples lose their homes and culture, resulting in the drop of the native population.
