Marine biologist who study the ocean need the bay to stay healthy. Marine animals that live there need the food that the Chesapeake Bay gives them. When people pollute the ocean they keep losing food.
A few ways we can help the bay are: 1. Plant a tree, when you plant trees and you spray fertilizer in the ground the trees soak up the fertilizer and keeps the erosion from getting into the bay and the ocean. 2. Some motorboats need to use oil or gas to work. If it has a leak the oil or that type of gas will get into the ocean and the bay and will affect the animals.
