.... first nuclear generated electricity. Ontario had found it’s new source of electricity, and they were not fully aware consequences that would happen after many years of use. Power projects (later AECL CANDU), based in Toronto. Ontario and Montreal, Quebec became responsible for implementing AECL’s nuclear power program and marketing CANDU reactors. Nuclear power was cheap, if you did not have to worry about the waste. This was the answer to Ontario’s power problems, so they invested in the newest source of power at the time. Most people believed that nuclear power was a good change in Ontario’s power structure, and there .....

.... smoking, intravenous injection, and in powder form using capsules. It is sold as a street drug and it is for readily available in the south western states and in areas where it is used in ceremony. Mescaline carries a wide margin for dosage error and has little or no withdraw effects, although the dangers do increase with higher dosages. A light dose (100-200mg) can give the user feelings of giddiness or anxiety, and a moderate dose of Mescaline (200-300mg) begins to impair the senses. Strong doses (300-500mg) will induce hallucinations and effect the user's perceptions of color, time, and space. Heavy does of Mescaline (500-700mg) and frequent us .....

.... way to soul development and growth. The soul's strengths and weaknesses are noted in the horoscope. Life is an opportunity given to soul for further enhancement. Because the heavens are in constant motion, and because this motion is quite ordered and exact, it is possible to project the positions of the sun, moon, and planets for any given time. Astrologers use this information to draw-up a horoscope and forecast the "influences" that will affect the soul at that time. Astrologers usually do not predict actual events in the future. They can only say what might happen, or could happen, but not what will happen--much like a weather forecast; although m .....

.... sun ( Rowland, 1992, p.66 ). This natural umbrella protecting mankind has recently suffered the effects of industrialized society. This " ozone shield is dissipating " and the cause is laid primarily to man - made chemicals ( Bowermaster et al, 1990, p.27 ). If enough of these man - made chemicals are released, "the ozone layer would be weakened to such an extent that it does not filter out the sun's invisible and dangerous ultraviolet rays " ( Jones, 1992, p.36 ). Such a scenario would drastically alter society and the environment. Ozone depletion has been described as "potential catastrophe " and " a planetary time - bomb " ( Way, 1988, p.9 ). The .....

.... small quantities, but one kilogram of the most common CFCs may have a direct effect on climate 1000 times large than that of one kilogram of carbon. In addition over the last two decades the percentage increase of CFCs in the atmosphere has been higher than any other greenhouse gas. By 1990 the increase was 4-12% a year. CFCs also destroy ozone - itself a greenhouse gas - their net effect on climate is unclear. The strength of the indirect effect of ozone depletion depends on variables such as temperature of the upper atmosphere and cannot yet be measured with any confidence. According to new research, however, it is possible that the in .....

.... one whale. There are different types of animal stories that people hear about. There are the wonderful stories about adorable animals that do something amazing or need our help. There are also stories about animals that are used in good and bad experiments. When you hear about the treatment of some animals for research, you feel like forgetting about research. One such story was in 1988, three gray whales got stuck in freezing waters in Alaska, the whales were at risk of drowning because the holes in the ice that they were using to breathe were slowly freezing over. a large rescue was put together that ended up involving the National Guard and the .....

.... the greenhouse effect is, we must first understand what a Greenhouse is. A Greenhouse is a building made either of clear plastic sheets, or of glass. The sun's rays go through the glass, and heat up the air inside the building, and they have a hard time getting out. These rays get trapped inside the building, and continually heat the air inside, and even through the night the rays stay in and heat the air. The greenhouse is also called a "HOT HOUSE" because it gets so hot. The greenhouse effect is caused by gases such as carbon monoxide, carbon dioxide, and nitrogen escaping into the atmosphere. These gases get trapped in the ozone layer and .....

.... does have the ability to walk upright and does, but it spends most of the time walking on four limbs. It uses it’s arms as it’s front legs and walks on it’s knuckles. Our brain capacity is about twice as large as that of the chimp. Humans have a brain capacity of 1300 to 1500 cc, while the chimps are about 600 - 800 cc. It is though by scientists that our brain size grew over time as were evolved into making complex tools and we became increasingly sophisticated. The human skull is slightly different from that of our primate ancestors, these changes occurred over thousands of years of evolution. Over time the humans skull and teeth have .....

.... generally note. Again he fails to let the reader know the credentials of the cancer researchers. Another example of poor credentials is when Viscusi states some percentages in "a 1991 survey of company smoking policies". He again fails to let the reader know the credentials of the survey. Another explanation as to why Viscusi's article is not successful is because the organization is confusing. The thesis Viscusi is trying to prove is that the are exaggerated. He fails to support his thesis because his main points in his story are all scattered and have no organization. Also, Viscusi's main point is that risks are exaggerated, but he fai .....

.... definitions of black boles are somewhat sceptical. Generally, a black hole is an area of super-concentrated mass. So concentrated, that no object can escape its gravitational pull. In other words, once you get caught by it’s graviational pull, you aren’t getting out again. The velocity you need to break away from a graviational pull is called the "escape velocity". Roughly, earth’s escape velocity is about 25,000 M.P.H. (11.2 kilometers/second). Earth’s mass is nothing compared to the mass of a star that has the potential to become a black hole. A black hole has so much mass in such a small area, that its escape velocity is greater than th .....
