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

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

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