Ptolemy
Ptolemy Introduction In ancient times there were many great ideas which began to shape the way man perceived his environment. However, there were few minds who were able to put all of these ideas together. One of these minds belonged to Claudius Ptolemy, or just Ptolemy as he is commonly referred to. We know almost nothing of the chronology of Ptolemy's life, and we don't even know his birth or death dates. We do know, though, about his ideas in several fields, which include geography, astronom...

The Worlds Natural Resources Are Being Consumed At An Alarming Rate. A
The world's natural resources are being consumed at an alarming rate. As these resources diminish, people will be seeking alternative sources by which to generate electricity for heat and light. The only practical short term solution for the energy-crisis is nuclear power. Nuclear power, however is not as safe as burning coal, gas or oil in a factory it is in fact , much more dangerous, There are dangers associated with a nuclear power plant which far out weigh the benefits to society as a whol...

Introduction
Introduction The discipline of archaeology can open up the past to us in a way in which we can enter into a dialogue with our ancestors. There are many ways it can do this: stratigraphic excavation, pottery typology, socio-historic interpretation, etc. However, one thread running through this increasingly focused pursuit is that of dating the physical findings to a particular cultural timeline. This is crucial if we are to know, with as much certainty as is allowed, who we are speaking with. In...

Where Have They Gone?
Where Have They Gone? For many reasons the human race could be called a blessing. Great advanced in technology, medicine and even the fact we are the most sophisticated species on the planet. Are we a gift to planet Earth, or far from it? With cast amounts of pollution and destruction of the planet, not to mention unthinkable acts of violence and hate that has been going on since the beginning of time. Are we really as sophisticated and important as we have led ourselves to believe? Are we any b...

Steinbeck
Steinbeck John Steinbeck A Common Man's Man ?I never wrote two books alike?, once said John Steinbeck (Shaw, 10). That may be true, but I think that he wrote many of his novels and short stories based on many of the same views. He often focused on social problems, like the ?haves? verses the ?have nots, and made the reader want to encourage the underdog. Steinbeck's back ground and concern for the common man made him one of the best writers for human rights. John Steinbeck was born in Salians, C...

Depletion Of The Ozone Layer
Depletion of the Ozone Layer Depletion of the Ozone Layer CHEM 151 Research Paper July 11, 1996 The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne mi...

Man has been the main cause for the decline in Chinook salmon populations. The populations of Chinook salmon have declined for se...

Creation Vs Evolution
Creation Vs Evolution There are many different life forms on earth. New species and different sub species are evolving every second as others die out. In order to explain the origin of life, people have used the bible story of creation, while others came up with their own theories. Out of all those theories, the theory of evolution by Charles Darwin seems to have the most supporting evidence to back it up. Evidence on earth suggests that single cell creatures are the ancestors of all life. These...

Air Quality
Air Quality Air Quality & Dispersion Today, the air quality aspect of ARL research is by far the dominant theme, but distinctions among the themes remain somewhat vague. For example, the models developed for emergency response purposes are among those used for air quality prediction. The Air Quality and Dispersion theme is one of the strongest ties that binds ARL's components together. ARL is not heavily involved in the pure science of the business. Instead, ARL focusses on the need to assemble ...

Ocean Dumping
Ocean Dumping Ocean Dumping The practice of ocean dumping should be banned. Marine pollution is at the heart of interest in today's search for a clean environment. Not only does ocean dumping add to the unsightliness of the once beautiful and pristine waters; it also kills the marine life which inhabits those waters. Pollution on a grand-scale is wreaking havoc on the Earth. The ocean is not an exception. In 1996, a bill, which would ban the dumping of dredge spoils in the Long Island Sound, was...

Exxon Valdez
Exxon Valdez INTRODUCTION On March 24, 1989 at 4 minutes past midnight, the oil tanker ExxonValdez struck a reef in Alaska's breath-taking Prince William Sound. Instantaneously, the quiet waters of the sound became a sea of black. We've fetched up - ah - hard aground north of Goose Island off Bligh Reef, and - ah - evidently leaking some oil, Joseph Hazelwood, captain of the ship, radioed the Coast Guard Marine Safety Office back in Valdez.

Coral Reefs
Coral Reefs Coral reefs are arguably the world's most beautiful habitats. Coral reefs have been called the rainforests of the oceans, because of the rich diversity of life they support. Scientists have not yet finished counting the thousands of different species of plants and animals that use or live in the coral reef. There are three types of coral reefs: fringing reefs, barrier reefs, and atolls. Fringing reefs are located close to shore, separated from land by only shallow water. Barrier reef...

Endangered Species In Canada
Endangered Species in Canada There are many trillions of living creatures, and millions of different kinds of animals and plants share our planet (pg 46, Savage). Each Kind, or species, is special and unique. But, some of these species are in danger of disappearing forever, just as the passenger pigeon did. When the last member of a species disappears, that species is said to be extinct. Never again will there be another creature of that type on the planet for eternity. In the following essay it...

Mans Attitude Towards Nature As Being Superior
Man's Attitude Towards Nature as Being Superior As mans attitude towards nature evolved, western culture perceived man as the central and most important part of nature. This egocentric attitude has acted to the extreme detriment of nature. Yes, I believe this to be true and I will prove it by looking at resourcism and speciesism. Resourcism is the exploitation of the worlds resources. Our consumption rate, especially in the western world, is overwhelming. In the beginning, we were a hunter and g...

Moon Flight
Moon Flight On May 25, 1961, John F. Kennedy delivered one of the most memorable State of the Union addresses in the history of the United States. I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the earth (http://www.cs.umb.edu/jfklibrary, President John F. Kennedy's Special Message to the Congress on Urgent National Needs). With those words, Kennedy launched a new era of space explorati...

Oceanography From Space
Oceanography From Space At first thought, studying the oceans from space seems to be a bizarre idea. Space observation helps oceanographers do research with manned and unmanned space systems. The space systems can be satellites and/or space shuttles that observe various features of the ocean such as sea-surface winds, sea-surface temperatures, waves, ocean currents, frontal regions, and sea color. Technological advances have greatly improved the ability of oceanographers to gather and use infor...

They wanted him to have a true profession as a l...

Aquaculture
Aquaculture Aquaculture is the farming of aquatic organisms in fresh, or salt water. A wide variety of aquatic organisms are produced through aquaculture, including fish, crustaceans, mollusks, algae, and aquatic plants. Unlike capture fisheries, aquaculture requires deliberate human intervention in the organisms' productivity and results in yields that exceed those from the natural environment alone. Stocking water with (juvenile organisms), fertilizing the water, feeding the organisms, and ma...
