Earth’s Environmental
SystemsChapter 3 – Environmental Science
Central CaseAfter reading the Central Case, who do you think
is responsible for the Gulf of Mexico’s dead zone?
What do you think is the best way to go about solving the problem?
Section 1 – What properties of matter are most important to environmental
systems?Chemistry is CENTRAL in understanding what
environmental problems are occurring and in how to correct them.
We begin this chapter with an introduction to basic chemistry….
