Happy Earth Day!
Happy Earth Day! The purpose of the day is to inspire appreciation for
the earth's environment and awareness of issues that threaten it. With
that in mind, here's a look at some environment-related chemistry. I
selected features that focus on cool features of the environment, like
snowflakes and changing leaves, as well as issues, such as the
greenhouse effect and fluoridation of drinking water.
