Environmental Science Fields
of Study
Environmental science is interdisciplinary:
Ecology – How living things interact with each other and their nonliving
For example: A ecologist might study the relationship between bees and the
plant that bees pollinate
Chemistry – Helps us understand the nature of pollutants
Geology – Helps us model how pollutants travel underground
Botany and Zoology – Provide information to preserve species
Paleontology – Can help us understand how Earth’s climate has changed in the
What Are Our Main
Environmental Problems?
Resource Depletion:
- Any natural material that is used by humans is called a natural
- These resources can either by renewable or non renewable
- Renewable: ones that can be replaced relatively quickly by
natural processes
- Examples – water, air, soil, trees and energy from the sun
- Nonrenewable: ones that form at a much slower rate
- Examples – minerals and fossil fuels
- An undesired change in air, water, or soil that adversely
affects the health, survival, or activities of humans or other
Loss of Biodiversity
- Biodiversity is the number and variety of species that live
in an area
- Organisms are considered a natural resource and if they
become extinct they are considered a nonrenewable
