Watersheds!

Definition A watershed is the region draining into a river, river system, or any other body of water.

US! We are a part of the Chesapeake Bay Watershed. (NNN) Any others?

Wetland Defined! A wetland is an area of land saturated with moisture, such as a swamp, marsh, or bog. A wetland can be fresh or saltwater.

Importance? More ___________ = More types of life? Wetlands are important because of their biodiversity! They can support an immense variety of plants and animals!

Wetlands? Watersheds????! ALL WATERSHEDS FLOW INTO WETLANDS! Whatever the river carries gets deposited in the wetland, including pollutants! Would you want to swim in that? BLEHCH SO GROSS!!!

Bad effects of polluted watersheds! Low fish numbers!!!!! Loss of biodiversity Poor drinking water Loss of animal habitats Loss of fun!

Examples of Pollutants Fertilizers and Manure Air pollutants Pesticides Industrial Chemicals Mercury Hydrocarbons (Result from gas and oil being burned)

Avoiding pollution Limit driving Use natural fertilizers Create a stream buffer to catch soil and run off.
