Environmental Science

4. All nonliving and living things around you.
5. Resource that exists in a fixed amount and takes millions to billions of years to form, so it will be used more quickly than it can be replaced. Examples include copper, aluminum, coal, oil, salt, and sand.
8. Natural resources and ecosystem services that keep humans and other species alive and support human economies.
9. natural services that support life and human economies at no monetary cost. Examples are nutrient cycling, natural pest control, and natural purification of air and water.
11. Biological science that studies how living things interact with the living and nonliving parts of their environment.
12. Interdisciplinary study of how humans interact with the environment.

1. Resource available in continuous supply for the conceivable future. Examples include sunlight and the wind and flowing waters that sunlight powers.
2. Material or energy source in nature that is essential or useful to humans.
3. Social movement dedicated to protecting Earth and its resources.
6. Resource that can be replenished rapidly (in hours to centuries) through natural processes as long as it is not used up faster than it is replaced. Examples include forests, grasslands, wildlife, fertile topsoil, clean air, and fresh water.
7. capacity of Earth’s natural systems that support life to maintain stability or to adapt to changing environmental conditions indefinitely.
10. One or more communities of different species interacting with one another and with the chemical and physical factors of their nonliving environment.
