What environmental phenomenon is growing in Chesapeake Bay?
A giant underwater “dead zone” in the Chesapeake Bay is growing at an alarming rate because of unusually high nutrient pollution levels this year, according to Virginia and Maryland officials. They said the expanding area of oxygen-starved water is on track to become the bay’s largest ever.

Why is Chesapeake Bay dying?
There are three major contributors to the poor health of our streams, rivers, and the Chesapeake Bay—nitrogen, phosphorus, and sediment. High levels of nitrogen and phosphorus fuel unnaturally high levels of algae growth in the water, blocking sunlight from reaching underwater grasses that serve as food and habitat.
