USA: Chesapeake Bay Watershed
Did you know that while the Chesapeake Bay is cleaner now than it was a few decades ago, it still suffers from dead zones, sea grass depletion, and low oxygen levels that harm fish and other wildlife? Oysters are perhaps the most obvious example — oyster levels in the Bay are only 2% of what they were 200 years ago.
For more information on research being done in the Bay, check out the Chesapeake Biological Laboratory on Solomons Island.
