Excessive nutrients in the bay have negative effects on the bay's ecosystem. The extra nutrients make the environment unbalanced.

The language is easy to understand and the scientific and environmental message is conveyed in a way that can be followed. Summary of source The importance of the Chesapeake Bay is introduced.

Grass beds are essential to many of the organisms living in this ecosystem, but are being destroyed by pollution. Agriculture involves more than a fourth of the bay's watershed. This makes agricultural runoff a big focus. Excessive nitrogen and phosphorus causes eutrophication. These nutrients come from pesticides and sewage also. A goal was set in 1985 to cut back the percent of nutrients being put into the bay by these two sources. It is thought that redirecting the flow of soil with nutrients in them will reduce the runoff, but if the nutrients seep into groundwater they still get into the Chesapeake Bay.
