Learn the Issues

There are many problems facing the Chesapeake Bay. The major pollutant to the Bay is excess nutrients, which come from agriculture, urban/suburban runoff, vehicle emissions and many other sources. Excess nutrients fuel the growth of algae blooms, which block sunlight that underwater bay grasses need to grow. When algae die, they are decomposed in a process that depletes the water of oxygen, which all aquatic animals need to survive. Learn more about some of the issues facing the Chesapeake Bay:


Wetlands provide critical habitat for hundreds of critters while also improving the health of the Bay by collecting and storing flood waters, filtering polluted runoff and weakening storm surges.

Wetlands are critical in supporting the healthy waters and diverse wildlife of the Chesapeake Bay watershed. Located where land meets water, wetlands act like a sponge, soaking up storm surges and trapping polluted runoff. Wetlands also provide habitat to hundreds of fish, birds, mammals and invertebrates. But development, invasive species and sea level rise threaten these important areas. Protecting and restoring wetlands is a key way to promote clean water, healthy habitats and a restored Bay.
