Through thousands of years of natural selection forestpeople have evolved to be smaller than people who do notlive in the rainforest. They also sweat less because theforest's high humidity means that sweat cannot evaporate,making sweating a poor way to cool off.
Forest people alsodrink less water because their food contains a lot of water.
Forest people have accumulated a great wealth of knowledgeabout the forest and have learned how to live in the forestwithout damaging it. They know how to use thousands ofedible, medicinal and poisonous plants and how to grow cropsin the forest's poor soil. They also know how to hunt andfish without driving the animals to extinction.
