Objective Students will be able to describe how human activities affect the ecosystem as evidenced by reading text and accurate completion of worksheet 3.2

Review for test tomorrow:

Rachel Carson Founder of the environmental movement Known for her book Silent Spring and speaking out about pesticides (biocides)

Biodiversity is important to the ecosystem: Extinction rates decrease New Species are produced faster Species are lost slower More ecological niches available (jobs in the ecosystem) Keeps the entire ecosystem intact Enables more or a variety of species Maintains balances with biotic life (plant & animal, predator & prey) Produces a stable living environment More options available for plants and animals to meet their nutritional needs

3.2 Pollution Human activities affect the environment. Pollution and habitat loss make it difficult for plants and animals to survive. Without the necessary resources, biodiversity of living things decreases, and ecosystems become less stable. pollution biodiversity Pollution CHAPTER RESOURCES SECTION OUTLINE
