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:

Nutrients

Nutrient pollution fuels the growth of harmful algae blooms that block sunlight from reaching underwater grasses and lead to

Plants and animals need nutrients to survive. But when too many nutrients enter rivers, streams and the Chesapeake Bay, they fuel the growth of algae blooms and create conditions that are harmful for fish, shellfish and other underwater life. In fact, excess nutrients are the main cause of the Bay’s poor health.
