Population Essays (1309 words) - Ocean Pollution,

Automobiles like these are around the world everyday, and their exhaust destroys our air everyday. Our environment is a major aspect of our life today. Many of us don't take our Earth seriously and think that as long as pollution doesn't hurt them they can go ahead and throw garbage on the ground or spill oil down the drain. Well to many people have that theory and they are killing off our Earth and also physically harming themselves from the air they breath and the water they swim in. Our Earth is fragile like a human and people don't know. There are many different types of environmental pollution (e.g. Water, air, atmospheric.) Scientists believe that all cities with populations exceeding 50,000 have some degree of air pollution. Burning garbage in open dumps causes air pollution, and also it smells pretty bad. Air pollution comes from many different sources. One of the major sources is carbon monoxide which manly comes from automobiles, but also burning of fossil fuels, CFCs etc. Air pollution does not leave the Earth it all gets trapped up in the atmosphere. This doesn't bother most people, and they think that it will not harm them. People burn down forests and people burn fossil fuels, and CFCs from aerosols. Every bit of this harms our atmosphere. Factories and transportation depend on huge amounts of fuel billions of tons of coal and oil are consumed around the world every year. When these fuels burn they introduce smoke and other, less visible, by-products into the atmosphere. Although wind and rain occasionally wash away the smoke given off by power plants and automobiles, the cumulative effect of ai r pollution poses a grave threat to humans and the environment. A big example of smog is LA you can see the smog just hovering above the city. I don't think any human alive should be subject to that kind of environment. Scientists believe that all cities with populations exceeding 50,000 have some degree of air pollution. Burning garbage in open dumps causes air pollution Scientist have discovered that over the South Pole the ozone has a high level of ozone depletion. A computer-enhanced map, taken from satellite observations of ozone levels in the atmosphere over the South Pole, shows the region of ozone depletion that has begun to appear each spring over Antarctica. When you look at this picture you can see the big red spot right above the South Pole. If this depletion opens up dangerous and deadly UV Rays from the sun will come into Earth. Air pollution causes global warming which scientist believe is making the Earth warmer and melting ice up in the South and North Pole. The country Holland has had water from the ocean got too high for them and flooded into towns. Holland spent millions of dollars to put up "dikes" which are big barriers in the water to prevent their town to be completely submerged. With the ocean getting deeper coastal cites all around the world could flood, billions of dollars would be spent to try to prevent it, but in a while it could not be stopped. Instead of waiting and having to spend all this money why don't we put it together today and try different ways of preventing air pollution, it would be much easier than all the trouble of stopping flooding. Water pollution is another major aspect of environmental pollution. Water pollution is scary because over 75% of our Earth is covered by the ocean. Water pollution comes from many different sources around the world. One major pollutant that destroys the ocean is oil spills. The oil from an oil spill kills hundreds of sea animals from fish, to whales, to birds. Below is a small list of just some of the major oil spills. Notice how many tons were spilled into our ocean... Notable Oil Spills Date Location Description Tons spilled Jan.-June, 1942 East coast of U.S. German U-boat attacks on tankers after 590,000 March 18, 1967 Land's End, Cornwall, England Grounding of 'Torrey Canyon' 119,000 June 13, 1968 South Africa Hull failure of 'World Glory' 46,000 Nov. 5, 1969 Massachusetts Hull failure of 'Keo' 30,000 March 20, 1970 Tralhavet Bay,
