... 269 million tons of municipal waste which is an average of 1.089 tons per person. In 1997, this had increased to 340 million tons which is an average of 1.272 tons per person and this amount is getting higher and higher each year and we need to put a stop to this. Trash is not a problem far from us, it is right here in our community. People are throwing things on the floor all the time and recycling has not been done as much as it should be. In New York city we have one of the world’s most largest and most crowded landfills which is proven in the article. Fresh Kills landfill, on Staten Island is extremely big but will be closed in a few years. I Ne ...

... ahead and changed their course. In a few minutes, all four of the fuel pumps had failed. The worst possible news, they were out of fuel. In a few more minutes the engines stopped running, and all of the high tech instruments became useless. They realized that they could not even make it to Winnipeg. Their only chance was an abandoned to a abandoned Air Force airstrip. Unfortunately, the airstrip had been converted to a race track, complete with race cars, fences, and spectators. The 767 crash landed, and, fortunately, no one was killed. Their were many contributing factors that made this plane run out of fuel. First of all, the computerized fuel gauge ...

... seen in basketball, where players must shoot the ball with enough arch to get over the front of the rim, and go through the hoop. The energy required to do this comes from not only the arms, but the legs as well. The medical field has seen enormous breakthroughs because of principles of physics. Doctors are now able to use lasers for surgery. Lasers are based on the physical principle of light, and are devices for the creation and amplification of a narrow, intense beam of coherent light. New laser microsurgery can actually alter the shape of the cornea in the eye so the patient's eyesight can return to normal, and he/she will no longer need those bothersome ...

... but instead act as catalysts inside the body. One variety of vitamins is the Vitamin A. This group includes retinol and carotene. Carotene is a yellow pigment found in vegetables such as carrots. A diet that is lacking in Vitamin A depreciates a person’s ability to see in the dark. Which is where the saying that carrots will make you see better is derived from. Carrots were the vegetables chosen to be tested in this experiment. This experiment was designed to test if the processing of a carrot produces gas. In turn discovering the health related differences of canned, frozen and fresh carrots. Canning is a process of hermetically sealing cooked food for future us ...

... the possibility of interferences with the normal life cycles of animals and plants would become more of a reality, with the eventual possibility of death. Stratospheric ozone has been used for several decades as a tracer for stratospheric circulation. Initial measurements were made by ozonesondes attached to high altitude balloons, by chemical-sondes or optical devices, which measured ozone concentrations through the depletion of UV light. However, the need to measure ozone concentrations from the surface at regular intervals, led to the development of the Dobson spectrophotometer in the 1960s. The British Antarctic Survey has the responsibility to routinely ...

... at his results of these laws, by inventing a form of entirely new branch of mathematics, calculus, which has become an essential tool in most branches of physics. Therefore, I have come to state that physics is considered as “a body of knowledge and as the practice that makes and transmits it. The growth of physics has brought not only fundamental changes in ideas about the material world, but also, through technology based on laboratory discoveries, a transformation of society.” Uncertainty in Measurements Because the number of digits that are valid for any measurement is limited, the precision of all measuring devices is also limited. Every measurement is subj ...

... ecosystem will not be capable of supporting the same amount of life. If one species hogs the food and does not contribute itself to the food chain, the balance is disrupted and there will be less available for the native species. Once the new species has found its ecological niche however, balance begins to restore itself. When the biodiversity in the ecosystem is reduced, the ability of the ecosystem to grow, or the biotic potential, is as well reduced. More species residing in an ecosystem which depend on each other allows for a greater chance of survival and perpetuation. This may occur for several reasons, for example a bee and a flower. The bee requires ...

... Noranda Mines Ltd. - Welland, and (3) Sulfide - Ontario There are a number of factors which govern the location of each manufacturing plant. Some of these factors that have to be considered when deciding the location of a Sulfuric Acid plant are: a. Whether there is ready access to raw materials; b. Whether the location is close to major transportation routes; c. Whether there is a suitable work force in the area for plant construction and operation; d. Whether there is sufficient energy resources readily available; e. Whether or not the chemical plant can carry out its operation without any unacceptable ...

... less than 10 pounds per week per person. The typical weekly diet in the U.S. is about 17 pounds, which means a significant number of the worlds people are eating considerably less than the average of 10 pounds per week. A world population of 10 to 11 billion by mid century will have an individual allocation of 6 to 7 pounds per week, equivalent to the diet of todays members of society living in poverty. Food projections are extremely uncertain since natural disasters are unpredictable and may increase if the forecasted effects of global warming materialize. Also, environmental degradation is increasing while water allocations are decreasing. Society will not be su ...

... but differ in terms of their mitochondrial DNA, which is vitally important for the regulation of the cell. The media and the press ignored this fact, and thus claimed that Dolly and her “mother” were genetically identical, which sparked a fury of outcry all around the world. The technique of transferring a nucleus from a somatic cell into an egg cell of which the nucleus had been removed, called nuclear transplantation, is an extension of research that had been ongoing for over 40 years. Up until now, scientists thought that adult cells could not be “reprogrammed” to behave like a fertilized egg and create an embryo, but the evidence obtained by Dolly’s su ...
