Environmental Science
One or more communities of different species interacting with one another and with the chemical and physical factors making up their nonliving environment.
Ecosystem

Natural resources
Anything that we can obtain from the environment to meet our needs and wants.
Resource
A resource that takes anywhere from several days to several hundred years to be replenished through natural processes, as long as it is not used up faster then it is replaced.
Renewable source
The highest rate at which we can use a renewable resource indefinitely without reducing it’s available supply.
Sustainable yield
Resources that exist in a fixed quantity, or stock, in the earth’s crust and has the potential for renewal by geological, physical, and chemical processes taking place over hundreds of millions to billions of years.
Nonrenewable resources
Involves using a resource over and over in the same form.
Reuse
Involves collecting waste materials and processing them into new materials.

Pollution
Broad and diffuse areas, rather than points, from which pollutants enter bodies of surface water or air.
Non-point sources
Single, identifiable source that discharges pollutants into the environment.
Point sources
Threshold level at which an environmental problem causes a fundamental and irreversible shift in the behavior of a system.
