... d's population, yet consumes 26% of the world's energy. Imagine what life would be like without electricity? At present most electricity is produced using non-renewable resources like coal but this cannot continue forever. The common characteristic of renewable energy resources is that they are never going to run out. Compared with non-renewable resources, renewable energy is difficult to use and more expensive at present. Not only could renewable resources solve future energy needs but they could also help to reduce environmental problems. Oil is an example of a non-renewable resource. It is obtained from oil fields and is transported to oil refinaries where it is turned into various ...

Fossil Fuels - 1,111 words
Part One - Introduction Fossil Fuels are the most important energy sources in our world today. The overwhelming majority of the huge amount of energy used in the world comes from the burning of three major fossil fuels: coal, petroleum, and natural gas. Fossil fuels are a non-renewable source of energy, and there is no other . They are formed over a very long period of time; the fossil fuels on earth today were formed from plants and animals that lived up to 300 million years ago. These fossil fuels are found in deposits deep beneath the earth. The fuels are burned to release the chemical energy that is stored within this resource. Energy is essential to modern society as we know it. Over 85 ...

... re known as 'wildcatters.' A fabled technique used by the wildcatters is the 'old hat.' They would basically toss their hat up in the air and wherever it landed, they drilled. When the wildcatters got lucky, and struck oil, it would typically gush up the drill pipe, hence, a gusher. Because gushers are a safety hazard and environmental concern, oil companies today contain them. After discovering an oil field, it is the task of the oil company's engineers and technicians to get it out. Not all oil fields turn out to be gushers and even the ones that are eventually loose pressure, leaving a lot of untapped fossil fuel resource in the reservoir. Even with modern extraction techniques, 100% ...

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 ...

Signifance Of Anthropology And Archaeology - 1,521 words
Anthropologists and Archaeologists Anthropologists and archaeologists have influenced our lives in so many ways. They have taken us back to our most humble beginnings. They have given us an awareness of just how far we have come through the centuries. Archaeology is the investigating of life by unearthing and interpreting the objects left behind by earlier peoples and cultures, dating back to prehistoric times. Anthropology is the scientific study of hominids, their physical features, development, and behavior. Anthropology is broken into two parts: physical and sociocultural. Physical is concerned with human evolution and biology and the study of primates. Sociocultural anthropology investi ...

Ice Age Extinctions Of The Megafauna - 1,630 words
... vironments than do smaller animals. Larger animals are safer from predators than small animals are, but it is also harder for them to sustain in trying conditions. Many of the larger animals such as mammoths and bison travel in herds, and that, along with their large size, protects them from predators. However, when the predator is Mother Nature, there is virtually no defense. For modern day elephants, drought is the biggest concern. It can take twenty percent of a herd every year, but the elephants continue to exist (Ward, 1997). It would have been harder though, for the mammoths and mastodons to survive a drought. Because of their size and weight, the Ice Age Proboscidea had longer ges ...

Multiregionalism Vs Out Of Africa - 1,033 words
Anthropologists today are debating two sides to the story of the evolution of the modern human Homosapian sapian. The sides agree on two different theories called the Out of Africa theory and the Multiregional (or Candelabra) theory. The debate, which some may call a slanderous argument, is far from being resolved on either side. Both evolutionist sides have strong evidence, however, this evidence does have its flaws and is not accurate enough to prove one side over another. However, the arguments for the Out of Africa theory seem to be flawed far more than those of the Multiregional theory. The Multiregional theory states that the hominid H. erectus. Migrated out of Africa through the north ...

Landing on your food and everywhere else. Some flies are favorable to humans, as parasites of bug pests or as scavengers and many others are important as plant pollinators. Flies are also understood to be carriers of diseases like cholera, typhoid, and dysentery. In most breeds of flies their body has padded feet that are coated with hairs and the tongue covered with sticky glue. Using a powerful microscope, bits of dust and dirt holding on to the hairs show bacteria that cause a broad variety of diseases. Fi ...

Big Oil And Bus Ethics - 1,760 words
It can be argued (convincingly) that human's usage of fossil fuels is responsible for a large part of the world's pollution problems. The area that I will discuss is the interaction that the big oil companies have had with the environment surrounding their businesses in Alaska. I will not tackle the issue of whether it is right or wrong to extract or use fossil fuels. Instead, I will ignore the larger issue and concentrate on specific issues concerning the Arctic Slope activities of oil companies in Alaska. Because the North Slope oil fields are on American soil, the regulation of the industrial activities is far more stringent than other areas in the world. If we compared the North Slope oi ...

I Would Rather Dream Vancouver Than Hong Kong - 989 words
I would rather dream Vancouver than Hong Kong. With its beautiful weather conditions and natural atmosphere, Vancouver is regarded as one of the most beautiful cities in the world. Hong Kong, on the other hand, is a booming center for industry and business that suffers from high urbanization and pollution. It is this extreme difference in both climate and scenery that makes Vancouver seem like a pleasant dream, compared to the nightmare that is Hong Kong. The mountainous forests and proximity to the Pacific Coast make Vancouvers atmosphere one of relaxation and leisure. Skiing, hiking and camping are just some of the many activities that the mountains resorts of Whistler and Cypress offer. T ...

Save The Rainforests - 1,585 words
The destruction of the rainforests is one of the most crucial environmental issues of our time. It is also one of the most misunderstood and neglected. There has been so much propaganda and publicity attached to this crisis that Save the Rainforests is becoming almost as clich as Save the Whales. Why dont we take this problem more seriously? Is it because we, as Americans, simply dont understand the devastating, long-terms consequences that continued deforestation of the rainforests would have? Is it because our own government is involved in the deforestation, either directly or by financing its development? Or is it because we live in a society of excessive consumption, oblivious to the pro ...

Creationism Vs Evolution - 1,016 words
Evolution is not only improbable but clearly impossible. Extensive evidence against evolution is uncovered with every major scientific discovery. Every evolutionist "fact" can easily be rebuked by creationists. Twelve supposed hominoids have been discovered and presented as supporting evidence to evolution. While in all actuality nine of the twelve supposed hominids are actually extinct species of ape. While the remaining three are completely developed humans. Neanderthals were once considered pre-humans by evolutionists but recent studies have shown that the Neanderthals are completely developed humans (Homo sapiens) suffering from bone diseases caused by vitamin D deficiency. Many textbook ...

Ecosystem - 1,145 words
An ecosystem is the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space. The principles underlying the study of ecosystems are based on the view that all the elements of a life-supporting environment of any size, whether natural or man-made, are parts of an integral network in which each element interacts directly or indirectly with all others and affects the function of the whole. All ecosystems are contained within the largest of them, the ecosphere, which encompasses the entire physical Earth (geosphere) and all of its biological components (biosphere). An ecosystem can be categorized into its abiotic constituents, includ ...

Stuff - 449 words
The problem of global warming, an increase in the average temperature on Earth, is getting worse. The Earth has warmed 0.3 to 0.6 degrees Celsius since the late 1800s. Scientists believe that the cause is the greenhouse effect, the process of trapping heat in the Earth's atmosphere because of the presence of large amounts of carbon dioxide, chlorofluorocarbons, methane, and nitrogen oxides. Less oxygen is being produced and cleaning the atmosphere allowing more of these gases to do its work on the environment. Automobiles exhausts are just one of the contributors to this problem. The burning of fossil fuels is another major influence to the increase in global temperature as well. The destruc ...

Environmental Hazards - 1,289 words
Every thing present in this universe is a part of environment including ourselves. Whether they are animals , living thing, or nonliving things. All of the external factors affecting an organism. These factors may be other living organisms (biotic factors) or nonliving variables (abiotic factors), such as water, soil, climate, light, and oxygen. All interacting biotic and abiotic factors together make up an ecosystem. Organisms and their environment constantly interact, and both are changed by this interaction. Additionally, environmental factors, singly or in combination, ultimately limit the size that any population may attain. This limit, a population's carrying capacity, is usually reach ...

Nonpoint sources-runoff water containing pesticides and fertilizers from acres of agricultural land, for example-are much more difficult to control. Pollution arising from nonpoint sources accounts for a majority of the contaminants in streams and lakes. With almost 80 percent of the planet covered by oceans, people have long acted as if those bodies of water could serve as a limitless dumping ground for wastes. Raw sewage, garbage, and oil spills have begun to overwhelm the diluting capabilities of the oceans, and most coastal waters are now polluted. The pollution ...

Many differing opinions exist on what needs to be done about our current status of conserving energy and conserving our environment. With increased gas prices and energy costs, consumers are more aware of what benefits are available and the methods of obtaining them. The introduction of hydropower has been a major step for some, while a stumbling back for others. Advocates for hydropower have provided much information about the many benefits that we reap from using hydroelectric dams. Environmental activists denounce the many negatives that are created by the numerous dams located throughout the United States as well as other countries.

Global Warming - 681 words
The consequences of global warming have by now come to the attention of the majority of the population of the United States of America. The gradual warming of the earths atmosphere is due to an increased amount of carbon dioxide released into it. The burning of fossil fuels, oil, coal, and natural gas are the main activities that release carbon dioxide into the atmosphere. Americans add carbon dioxide to the atmosphere every time they drive their car, use a chainsaw, or use electricity produced at a fossil fuel power plant. The increased temperature due to the effects of global warming can be disastrous. Low lying areas and islands are in danger of being overcome by increased water levels in ...

... y behind the United States, Japans economy differs from that of China due to the governments minimal role in the economy. In Japan, the resources are always distributed through private channels rather than through the government, as in the case of China (Pilat, 177). The government only plays a role in the economy by actually allocating public investment and by consulting with businesses. Japans mixed economic system is responsible for the rapid rate of economic growth, especially after WWII. Japan is one of the worlds largest producers of automobiles, steel and high-technology manufactured goods (Pilat, 153).
