The ocean covers Seventy-one percent of our planets surface. Life isconcentrated, however, in about four percent of it, and it is this four percent that isbeing polluted by the tons every day.

And in order to preservethis other world of life, we must stop polluting the oceans, and begin to clean themup. Although using the ocean for a toxic waste dump may provide for a cheapalternative, we must not succumb to these barbaric urges. If we neglect to deal withthese ideals, than the world as we know it may not be as great a world for ourchildren as it was for us.First, we need to understand that the oceans are not the vast resources that webelieve them to be, but just vulnerable natural resources. Before Columbus' day,the ocean were thought to be boundless. Although Columbus proved this theoryincorrect, the thought still remains in today's societies.

Although the size of the ocean is often pondered, the thought that it mayone day be gone, is never even considered.The vast majority of all life in the ocean, inhabits only 1/25 of these waters,but it is these surroundings that are in the most danger. In the beginning of theworld, marine plankton was vital to the evolution of man. Today, it is even moreimportant to us, being that it provides us with a great percentage of oxygen wereceive. "These minute plant species manufactured so much oxygen that it roseabove the surface to help form the atmosphere we have today."(Heyerdahl)...
