- 5081: Ocean Environment
- ... ocean. Farther offshore this water covers an amazing submarine topography of underwater canyons, trenches, mountains, and plains. Unlike the continents, which are physically separated from one another, the oceans are continuous and interconnected. Since the "world ocean is continuous"(M.J. Keen) it has similar characteristics throughout. In the early 1870s oceanographers collected seawater samples from all of the seas of the world at a variety of depths. When analyzed, the samples were found to have quite similar characteristics. These findings convinced many that a method of study was needed. The study of oceans was named oceanography. Density ... these density barriers trap nutrients below the euphotic zone and make them spatially unavailable to the plants in these areas. This is the case in the tropical seas, as well as in all of the world's deep oceans, where the density barriers are permanent. Plant nutrients tend to cycle throughout marine systems, from their simple, low-energy, dissolved forms to plants, animals, and then to bacteria. When considering the ...

- ... wrong and criticized and therefor committed suicide. Since then there have been many other services, but the largest one currently is the National Weather Service. The National Weather Service gives predictions for all of the world through satellite imagery for all countries. Also in recent history many local television and radio stations have made private forecasts for small areas. Meteorologists are people who interpret the weather, the reason I don't ... connection by phone lines which can deliver photos and sound instantaneously. The next breakthrough in forecasting was the satellite. A satellite would be launched from Earth and then would take video and photos of the world and send back to Earth the footage, thereby being able to show storms coming from the ocean just at the first stages. The first weather satellite "T.I.R.O.S. 1"the world an infrared view of the world. However T.I.R.O.S 1 was not specifically built for forecasting but rather to study clouds. The U.S. government later went on to build 7 ...

With ... protecting nature in many countries has been to designate particular areas as national parks or nature reserves, and restrict land use changes or damaging activities within the designated areas”(Park 132). Many people in the world do not want to see the rainforest disappear; as a result , reserves are set up. In 1990 there were roughly 560 tropical forest parks and reserves covering a total of 780,000 km squared ...

It is a necessity to own or to have access to a car in order to keep up with all of the competition of the business world, and also one's social demands. Most people would not be able to travel around a country or the world without this incredible machine, for it provides freedom and mobility, even for people who do not own a car. Unfortunately, the car has a very destructive nature. Automobiles make a major contribution to air and ... is annihilated, the whole planet, including the human race, will be erased along with it. This is one reason gasoline powered automobiles should be limited. The automobile also contributes to noise pollution. Cities around the world are constantly packed with cars, and, as a result, there are traffic jams. Patience, as a virtue, is not always bestowed on everyone, and, therefore, people start honking their horns and yelling at others. ...

- ... snow. On a Native Island, where native tribes live, if the sea level rises three fourths of a meter then half of the island will sink. This will happen in many different islands around the world and if the water keeps on rising as it is, then farming land near the seashores will be flooded and the crops will be destroyed. Like California and other states, we are adding CO2 and ... age. Once the temperature reaches a certain threshold, the polar ice caps will began to melt. While those living in the Arctic may find that a welcome surprise, the implications for the rest of the world are serious.

Of course, inland cities are not immune either. Rather than floods, they will face drought. So while half the world is swimming to work, the other half will be crawling on their knees with a scorching sun beating against their backs. When drinkable water is a scarcity, it will become a commodity that represents ...
- 5087: Environmental Pollution

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 ... 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.

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' ...
- 5088: The Promise of Genetic Engineering
- ... can be used to humanity's best advantage. This speech will investigate the ways in which genetic engineering affects two important areas in today's society. The first one will be the improvement of the world's agricultural techniques. With an ever-increasing growth in world population, the Earth's resources are constantly becoming scarce. The advent of genetic engineering may be used to avert the occurrence of worldwide famine and starvation. The second one investigated will be in the field of medical development and study. Currently, genetic diseases are decimating the world's population. Thousands of people have already died without a single worthy treatment or cure. Worldwide acceptance and support of this technology would aid in our battle against these diseases. According to the United ...
- 5089: The Orgins of Atomic Theory

All western thought can find its roots in the philosophy and science of the Greeks, even the way we see the world is influenced by the ideologies of Ancient Greece. The Greeks were the first to seek a greater understanding of the world, to know "why" we are not just "what" we are. The Greeks invented science and explored it in its truest form, philosophy. Through the years we have developed tools that we hope can prove ...
- 5090: Geothermal Energy
- ... pollution that otherwise would not be introduced into the environment. I feel that the benefits of using geothermal resources as a source of energy for electricity and mechanical work production out weigh the downfalls. The world has many different geothermal regions that are exploited for the production of electricity and other things. The United States is one of the leaders in manufacturing geothermal produced electricity. One of the most productive regions ... future of geothermal energy looks very promising. There have been many technological breakthroughs that have resulted in increased efficiencies of modern day geothermal electrical plants. I feel that with the current environmental situation that the world now faces a viable method of clean up will include the use of geothermal power plants and resources. In a world that is suffocating from the chemicals, and particulates that are created in the production of electricity and other commercial industries, we have no choice but to change our ways. The earth can not support ...
