Two major goals of environmental science are
Understand and Solve environmental problems
How our actions alter the environment
REMEMBER: THIS IS NOT THE KEY GOAL

An Experiment consists of these two essential components
Control and Variable

Ecology is this
the study of how living things interact with each other and their nonliving environment
400
A developed country is
A country with higher income, and slower population growth. Includes America, Canada, and Japan
400
You have to do this when your experiments show that your hypothesis was wrong
Redo your hypothesis and do new experiments
400
The chance that something will happen is this
Probability

Hunter-gatherers affected the environment by
Set fire to forests and cut them down.
Caused some animal species to go extinct
One good one: Helped spread plants to areas where plants didn't normally grow
