Environmental Science - 2,306 words
Human kind has entered a brand new relationship with the earth. The constant and increasing pressures we are exerting threaten our planets ability to sustain life itself. Change-in the way we think , and in the way we live-is needed now. Global warming is the most urgent environmental problem the world will face in the next decade and the next century. Few, if any, trends are more important to our future than climate change caused by human activities. Scientist around the world are warning us that global warming poses a major threat to our future quality of life, previously there has been little information on this problem. Right now, the rate of global warming may be 100 times faster than i ...

The Greenhouse Effect - 1,061 words
While some people believe the earth's climatic changes are due to the fact that the universe is getting older, others believe it is due to the greenhouse effect. The greenhouse effect is a naturally occuring phenomenon that is responsible for trapping heat near the earth's surface and keeping the planet warm. It is called the greenhouse effect because the way it works is similar to the way in which a green house functions. In a greenhouse sunlight passes through the transparent roof and walls and strikes the objects inside- plants, flowerpots, tables, and so forth. These objects absorb energy from sun, become warmer, and then give off energy themselves in the form of heat. Only a little of t ...

Landfills - 1,511 words
When asked to think of the largest man made structure, people will invariably come up with an answer like The Great Wall of China, the Great Pyramids, or the Taj Majal. In contrast to these striking achievements of mankind is the Durham Road Landfill outside San Francisco, which occupies over seventy million cubic feet. It is a sad monument to the excesses of modern society [Gore 151]. One must think this huge reservoir of garbage must be the largest thing ever produced by human hands then. Unhappily, this is not the case. The Fresh Kills Landfill, located on Staten Island, is the largest landfill in the world. It sports an elevation of 155 feet, an estimated mass of 100 million tons, and a ...

The Impacts Of Chernobyl Nuclear Accident In The Us - 724 words
The Impacts of Chernobyl Nuclear Accident in the US Nuclear energy used to be a dream energy source because it did not emit air pollutants as long as they were operating properly. The US government and Utility Companies invested billions of dollars to build and develop nuclear power plants. However, its magic was collapsed on April 26, 1986. A series of explosions in a nuclear power plant in Chernobyl blew the massive roof off the reactor building and flung radioactive debris and dust high into the atmosphere to encircle the plant. Although the Chernobyl accident was thousands of miles away and did not cause direct damage to the US, we were able to experience the tragedy through the media. T ...

Tree And Plant Life Survey - 634 words
In this experiment, conducted by Mr. Luckinbill's AP and Advanced Environmental Science class, our goal was to take a trip into the woods behind the Blue Mountain High School and identify and find the relative dominance and density of the tree population and to identify the plant life as well. I believe that we will have found mostly oak and pine trees in the forest, at first glance, they seem to be the dominant trees. For this experiment, we took both a book of trees and a book on plants, and a measuring stick. When we got to the woods, we used something known as the quadrant method, in which we were given a spot, and we picked a tree in the 4 areas around it. For that tree we picked, we ha ...

Life Science And The Law - 1,637 words
One issue that has been a controversy is the preservation of endangered species. Ever since the 1960's, scientists have been fighting for laws and acts to protect animals and plants in keeping them in good health and their populations high in numbers. The problem is animals and plants are having trouble surviving in today's world which leads them to be classified as endangered or threatened. Endangered, meaning animals or plants with little population that the species could soon become extinct and threatened is less severe and basically just means that they are close to becoming endangered. By species becoming endangered, this affects our habitat's biodiversity. Today, however, human beings ...

Climate Change - 1,856 words
Introduction What is the oceans role in climate? The oceans play a vital and pivotal role in the distribution of life sustaining water throughout our planet. 86% of the evaporation that occurs on earth is over the oceans. The oceans are the planets largest reservoir of water transferring huge amounts of water around the hydrological cycle. In fact the oceans dominate the hydrological cycle, for they contain 97% of the global water inventory . The hydrological cycle can be disrupted by changes in ocean circulation that play such an important role on evaporation and precipitation. When the ocean circulation system changes it can change how much heat and rainfall is distributed around the world ...

Climate Change - 1,524 words
Climate change will have significant impacts on the global temperature such as an increase in temperature, change in weather patterns and sea-level rise. Sea-level is expected to rise 95 cm by the year 2100, with large local differences due to tides, wind and atmospheric pressure patterns, changes in ocean circulation, vertical movements of continents etc; the most likely value is in the range from 38 to 55 cm. The relative change of sea and land is the main factor: some areas may experience sea level drop in cases where land is rising faster than sea level. Indirect factors are generally listed as the main difficulties associated with sea-level rise. These include erosion patterns and damag ...
