Global warming is expected to change magnitude to the worse of the intensity of power of nature, such as storms, hurricanes, tropical cyclones and tornadoes. It is determined not by individual weather events, such as heat periods or cold snaps or hurricanes, but by the planetary average above ground temperature. It is already raising the intensity of hurricanes in the North Atlantic, increasing the risk of devastating impact when a storm strike.

Global warming is also the cause of more spectacular variations and changes in the weather in some areas. It is already affecting the world we know, endangering polar bears, cutting down ski seasons and creating more intense storms, hurricanes and cyclones. Global warming is a big gamble for an increase in the average temperature of the world’s surface.

It has been estimated by the U.S. Geologic Survey that there is 346 quintillion gallons of water in the worlds oceans. They are also quoted as saying that “95% of the water on this planet is contained in our oceans”. With this unfathomable amount of water one would come to the conclusion that water is an endless resource. This type of thinking is dangerously wrong.

For centuries, man has been dumping pollutants into the oceans and today, nearly all this water contains some level of pollution. It has been estimated that nearly half the world’s population lives within 100km (62 miles) of the coastline. This fact alone makes one realize that the problem of marine pollution affects a whole lot of people.

In an effort to reduce marine pollution, the direct dumping of pollutants such as toxic chemicals, human waste, and garbage directly into the ocean, had been banned worldwide since 1972. While these point sources of marine pollution have decreased, the amount of pollutants getting into the oceans from non-point sources continues to grow. Why is Marine Pollution Such a Concern?
