After studying the timeline above what observations can you make about the us environmental policy between 1970 and 1996

Environmental policy solves issues with the help of economics, natural science and permanent research.

The U.S. Environmental policy is divided in three stages:

-The First Period(1780-late 1800's)

-The Second Period(late 1800's-mid 1900's)

-The Third Period((mid 1900's-present)

In the timeline of the recent period you can observe the following.

1.- The creation of "The Earth Day" in 1970. This was an effort to create consciousness in people about the overuse of natural resources.

2.- From 1970 to 1995, many environmental laws were enacted by the Congress. For instance, the National Enviromental Provision Act, Endangered Species Act, Safe Drinking Water Act, Toxin Substances Control Act, Food Security Act, and the Pollution Prevention Act.

Those laws help us protect the environment and natural resources, a very important thing to combat global warming.
