Anticipation Guide StatementBeginning of Class 1.About half of the species of life on earth have been named and classified. 2. There are about 50 million species of living things on earth. 3. Many common drugs we take are from plants and other living things. 4. As a single person, there is little I can do to protect plant biodiversity. 5. Humans are dependent on biodiversity for survival 6. Agriculture (farming) never has any negative effects on biodiversity. 7. “Biodiversity” means “the variety of life on Earth”. 1.All human activities depend directly on the environment.

 Rainforests are most notable for the hundreds of prescription medications they provide through their rich plant life. One fourth of cancer fighting drugs are made from ingredients found in rainforests around the world. The plants solely in the Amazon rainforest produce more than 20 percent of the world's oxygen. The rainforest contains over varieties of fruit as well as a multitude of spices. We obtain many natural resources from the rainforest including fuel and rubber. They are also immense freshwater reservoirs. Rainforests maintain a delicate ecosystem balance. Disrupting that balance leads to destruction of the forest in ways that increase air nad water pollution. Rainforests have secondary metabolites that protect plants from insects and disease. Without these plants are more susceptible to any type of intrusion, i.e. human interaction.
