Gulf of Mexico dead zone.

These zones happen because of low oxygen concentration that animals suffocate and die. The Gulf of Mexico is home to one of the largest dead zone in the ocean. In the spring when farms prepare to grow crops, the when the rain comes it washes the fertilizer down into the Mississippi River and into the Gulf of Mexico. The Great Lakes are also a victim of dead zone. No part of any ocean of river of lakes are immune to these dead zones. So how do they occur? Many costal waters start by the combination of biological and physical factors.  It  starts with nutrients, caused by agriculture and urban research with watersheds in the water. Ocean Dead zones are parts of he ocean that have low oxgen and aqutic animales cannot live there or they will surley die. This is a big problem beacuse if we don't take care of it than a cetin amount of fish and other animales in the ocean will die.
