TEACH: Environment explores the environment of the Great Lakes region, which is blessed with huge forests and wilderness areas, rich agricultural land, hundreds of tributaries and thousands of smaller lakes, and extensive mineral deposits.

Protection of water quality and sustainable development remain long-term goals.
