A dead zone is an area of water where there is no oxygen, so the fish all die. There are “dead zones” in the Gulf of Mexico every year, but the current zone is the biggest anyone there has ever seen. Keep reading to find out why dead zones mean more SHARK ATTACKS on swimmers!
BBC News reports that “conditions are right” for this year’s zone to be even bigger than last summer’s, which measured 6,662 square miles. Dead zones are caused by fertilizer runoff. Fertilizer contains nitrogen, which stimulates the growth of algae, which then absorb all the available oxygen, leaving none for the fish.

There is an emergency going on in the world’s oceans that most of us know nothing about: as certain species of fish that are overfished or stressed due to pollution or changes in water temperature become drastically reduced in number, this changes the whole balance of the ocean ecosystem, causing more species to go extinct, etc. Since many societies in the world rely on fish to eat, this is a disaster in the making.
