What are Dead Zones

They are hypoxic zones are areas in the ocean of such low oxygen concentration that animal life suffocates and dies, and as a result are sometimes called "Dead Zones." One of the largest dead zones forms in the Gulf of Mexico every spring. Each spring as farmers fertilize their lands preparing for crop season, rain washes fertilizers off the land and into streams and rivers.

How can dead zones be prevented?

People can use less fertilizer around the ocean and rivers, pollution is one thing we can get rid of but cities near the ocean can use cars and motor vehicles less, and big oil companies can stop or reduce the amount of oils spill in the ocean. And oil spills are the number one cause of dead zones and sewage being dumped by industrial companies.
