  2. A. What is Environmental Science? • 1. Study of the environment that includes the physical, biological, and social sciences.

  3. A. What is Environmental Science? • 2. Goals • Use of natural resources • Learn how we affect the environment

  4. A. What is Environmental Science? • 3. Fields of Study • Biology (Study of living things) • Chemistry (Study of chemicals/interactions) • Earth Science (Study of non-living systems)

  5. A. What is Environmental Science? • 4. It is Important because it teaches us to maintain a healthy and productive society.

  6. QUICK LAB! • 1. You and a partner will receive a bag with objects inside. • 2. You will work separately, without discussing, at first and classify each object into 1 of 2 categories: Renewable or Non-Renewable. • 3. When you are both done, you will compare answers. Discuss WHY you answered the way you did.

  7. Post-Questions • 1. Why are resources like air and water considered at risk when they are renewable? • Due to so much pollution, sources of CLEAN air and water are more difficult to find. • 2. Select one resource and hypothesize what side effects might happen if that resource goes away.

  8. B. What are Main problems? • 1. Resource Depletion • Natural Resources are any material used by humans. • Renewable- can be replaced • Non-renewable- can’t be replaced • Depleted- Many of the resources have been used up.

  9. B. What are Main problems? • 2. Pollution- undesired change in air/water/soil that negatively affects living organisms.

  10. B. What are Main problems? • 3. Loss of Biodiversity • # and variety of species living in an area • Many species are extinct today • Ex: Tasmanian Tiger extinct in 1986
