Abstract Dead Zones-Another Puzzle History tells us that pollution in the atmosphere and the earth has been a grave concern since the beginning of recorded history and the first changes in the earth’s climate became noticeable. Since then the climate around the world has continued to change due to the pollution that is pouring into the atmosphere every day. As the atmosphere has changed so have the earth’s climates and the waters. Global warming is causing the oceans waters to grow warmer in areas where they were once cold and the marine life is dying because of it. Scientists are working with several renowned institutes to develop new ways of tracking global warming and its effects on the oceans. One phenomenon which has come to the attention of these groups is called dead zones; these groups are trying to determine what causes the formation of dead zones, by reading the oxygen levels in the waters and wind and ocean currents. With more scientific knowledge about what is happening to the oceans and the marine life there is hope that these dead zones can be reversed or at least kept from growing any larger.

The earths’ oceans are more than a place where food is harvested, or a means of travel. The earth could not sustain life without them. And now decades of polluting the atmosphere has caused global warming and it is believed that this is now destroying the oceans. Without immediately action the oceans, as everyone knows them will no longer be able to sustain the valuable marine life that it does today. Something must be done to stop the continued pollution of the atmosphere and end global warming before all the oceans are dead and it must be done now. Most people hear of global warming and the affects it is having on crops, climates and wildlife and yet few people realize that global warming is also affecting the oceans. As global warming changes the earths’ climates it is also affecting wind patterns, these wind patterns are what pushes the oceans waves and helps the currents to continue to move oxygen in the oceans waters, as these wind patterns change so does the pattern of how the oceans waves move. According to (Environment News Service October 8, 2009, “We did experience hypoxia conditions for the eighth consecutive year, but unlike 2006 when strong steady winds lead to near zero oxygen, or anoxic conditions, we got a break.” said Barth, “a series of wind reversals late in the summer helped dissipate the low oxygen, in essence allowing the system to flush its self.” Without these wind changes and continued strong steady winds, dead zones continued to
