.... to the essay by validating his point of view. In the same way, the author used effective illustrations and examples to prove his point. These examples and illustrations simplified the readers understanding as to how severe acid rain is and how we can try to prevent it. For instance, one great illustration adopted in the essay reports, “Lumsden Lake, on the north shore of Ontario’s Georgian Bay, twinkles like a sapphire in a setting verdant forest and sparkling quartz. Blue, incredibly clear, and seemingly pure, just twenty years ago it abounded in fish. But now, this exquisite la .....

.... of whether or not to go ahead cannot be delayed indefinitely as Norway and Spain are looking at developing their own. If it is to go ahead then an early start will give Harris a stronger position in the market. 2 INTRODUCTION This report examines the controversy and key issues surrounding the superquarry at Rodel, Lingerbay on the southern coast of the Isle of Harris (Figure 1) and attempts to find an acceptable solution. The quarry will hollow out the heart of the mountain but leave enough of a shell to leave the skyline largely unaffected. The whole question of whether or n .....

.... you wonder what that sticky black killer was. It's simple. It's crude. It's oil. This scenario is nothing but a harsh reality that most people were unconcerned about until the disaster of the Exxon Valdez. The Valdez spill, tragically unnecessary though it was, has served as a laboratory for scientists, in which they can study the effects of oil pollution and experiment with new cleanup methods. It has also served as a costly lesson in the pitfalls of petroleum shipping and the shortcomings of emergency plans. It is time for us to learn from such an expensive lesson, and learn th .....

.... in the United States. They have hybridized to some extent with resident wild and hive populations of European honeybees. However, many of the basic African honeybee traits remain, including rapid population growth, frequent swarming, minimal hoarding of honey, the ability to survive on sparse supplies of pollen and nectar, and a highly defensive nature. Africanized honeybees are more difficult to manage than European honeybees and produce less honey. The businesses of many beekeepers in Latin American countries have failed as a result of Africanization of the native hives. Africanized honey .....

.... are called incoherent. The process for laser action, was first proposed by Albert Einstein in 1917. The working principles of lasers were outlined by the American physicists Arthur Leonard Schawlow and Charles Hard Townes in their 1958 patent application. The patent was granted but was later challenged by the American physicist and engineer Gordon Gould. In 1960 the American physicist Theodore Maiman observed the first laser action in solid ruby. HOW A LASER WORKS A laser is made up of several basic components. One is called active medium, which consists of atoms of a gas, molecules in a .....

.... information sources, but computer crime has become one of the many risks that society must face if it would enjoy the benefits of modern technology. Imagine a world without . That would mean no proper means of communicating, no Internet, no video games. Life would be extremely difficult. Adults would have to store all their office work paper and therefore take up an entire room. Teenagers would have to submit course-works and projects hand-written. All graphs and diagrams would have to be drawn neatly and carefully. Youngsters would never have heard of 'video-games' and will have to s .....

.... name is Falco peregrinus anatum. At one time, people called this falcon a duck hawk. That was a poor name, since falcons aren't hawks and they rarely kill ducks. The American peregrine was once found all across the eastern United States and southern Canada. In the west, the species was found from Mexico to California. DDT poisoning hit this subspecies the hardest. Even today, naturalists are still working hard to save the American peregrine from extinction. The smaller tundra peregrine (Falco peregrinus tundrius) lives farther north. Tundra peregrines range across the treeless regio .....

.... three broad sectors: ? Small Office, Home Office (SO-HO) ? Games ? Industrial Use Because of the difficulty in separating consumer software purchased by individuals, into applications destined for use by businesses and the home user. I am going to primarily focus on So-ho, home user market, and takes account of the software packages bought, mainly through out the retail market for the small or home office and which may be used for business, education or simply leisure purposes. The most common software packages sold to the So-ho user market are the following: ? Business app .....

.... faster than most species can adapt to such changes through evolution, or natural selection. The current global extinction rate is estimated at about 20,000 species per year, exponentially greater than the background extinction rate (17). Many biologists believe that we are in the middle of the greatest mass extinction episode since the disappearance of the dinosaurs 65 million years ago (18). The survival of ecosystems (plant and animal communities and their physical surroundings) such as forests, coral reefs, or wetlands depend on their biodiversity or variety of plants, animals, and habita .....

.... 1997 was the warmest year on record. According to U.S. government satellites and weather balloons1997 as the seventh coolest year since satellite measurements began in 1978. Further more, satellite and balloon based information, which uses different technology, concur with each other's readings according to NASA. My opinion is that surface-based information can not be relied on until it covers more land. Also, I find it difficult to argue with two different sources that prove each other's information to be accurate. I do not, however, feel that we should immediately depend on the reliabil .....
