Nutrients are substances that are essential to life. They help plants and animals grow. But when too many nutrients enter waterways, they become a source of pollution.
In the Chesapeake Bay watershed, excess nutrients such as nitrogen and phosphorus cause algal blooms that deplete the Bay and its tributary rivers and streams of oxygen, making the water inhospitable to marine life. That’s why the Chesapeake Bay Foundation works to prevent these nutrient pollutants from entering waterways in excessive amounts.
In this video, join CBF Educators Maya, Ochae, and Nate as they scour their neighborhoods looking for sources of nutrient pollutants and the methods used to reduce them.
After watching the video, see if you can find sources of nutrients and stormwater management best practices in your own neighborhood in the Nutrients: Too Much of a Good Thing investigation.
