Taking a Trip Down to the Bay
How do WE impact the Chesapeake Bay?
Objectives• Students will be able to:– Recognize how humans impact ecosystems
through a local example; The Chesapeake Bay– Determine how humans in the watershed use the
bay– Determine what consequences those uses might
have and who they can affect– Demonstrate their knowledge of human impacts
on Bay ecology through a graphic organizer and writing.
SO… How do we use the Bay?•Fishing•Crabbing•Transportation•Swimming/boating•Tourism
Thinking About EcologyTwo Important Terms to Remember:1. Watershed- The entire area of land that drains into a body of
water2. Ecosystem- A group or community of organisms interacting with
their environment.
Are uses of the Chesapeake Bay limited only to the water?
NO!What are other uses of the Bay’s watershed that might impact its ecosystems? How?
Results of Human Impacts•More development= more impervious surfaces= runoff• Oil• Pollution• Nutrients• Sediment
•Dead Zones• Eutrophication- when there are
so many nutrients in the water that algae covers the surface and all the plants below die• Why would killing plants be a
problem?•Less Fish, Crabs, and oysters
What does this mean to you?
