.... mining, Mercury was dripping into the water. The mercury then got into the fish and into the humans who ate the fish. Biodiversity promotes a healthy environment. Environments rich in biodiversity are stronger and can with stand things such as drought, disease, and other stresses that environments that lack it cannot. In the video, during the drought, the side of the field with a more diverse environment held stern as the other wilted away. Areas that are very diverse are very important to humans as well. They provide a wide arrange of pharmaceuticals such as aspirin and penicillin. "Some 40 percent of U.S. prescriptions are .....

.... begins of occur at the hairline, then over time forms an “M”. The crown also begins to become thinner, as does the existing hair. Eventually, the “m” meets the thinned crown and forms the most common bald shape, the horseshoe. Currently, there are no treatments for male pattern baldness, so the condition is permanent. But, no treatment should be required if the person is comfortable with their appearance. At this time there is one drug that the FDA has approved for hair loss; minoxidil, which if used a-top the scalp twice daily could help hair grow in 10-20% of the population, but for 90% it will slow .....

.... large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers/lakes like the river Tovdal in Norway had not yet begun to die. However by 1926 local inspectors were noticing that many of the lakes were beginning to show signs of death. Fish were found dead along the banks of many rivers. As the winters ice began to melt off more and more hundreds upon hundreds more dead fish (trout in particular) were being found. It was .....

.... major sources of carbon dioxide presently and historically. They are industrial activity, land use change and cement plants. The carbon dioxide from industrial activity mainly comes from fossil fuel burning and is by far the most abundant of sources. The carbon dioxide from land use change comes mostly from deforestation which occurs mostly in Brazil, Indonesia and Columbia. The last major source of carbon dioxide in the earth's atmosphere is the emission from cement plants. Carbonaceous material used for making cement releases significant amounts of carbon dioxide. This source is fairly large since cement is used for roads, .....

.... mercury. The mercury came from industrial waste that had been dumped into the bay where the fish were caught. The mercury bioaccumulated up the food chain. The cats the were eating the fish showed the symptoms first. They began to act very strange; running into walls and acting like they were "in a trance." The people in the village developed mental retardation, insanity, and birth defects from eating the poisoned fish. Fifty people died and 150 people suffered from these disorders. Another example of mercury's effect on people and the environment comes from the saying "mad as a hatter." In the 1800's, hats were made wi .....

.... municipal and hazardous wastes may be co-deposited in order to gain benefit from municipal waste decomposition processes. The landfilling of hazardous wastes is a contentious issue and one on which there is not international consensus. Further complications arise from the difficulty of classifying wastes accurately, particularly the distinction between 'hazardous'/'non-hazardous' and of ensuring that 'inert' wastes are genuinely inert. In practice, many wastes described as 'inert' undergo degradation reactions similar to those of municipal solid waste (MSW), albeit at lower rates, with consequent environmental risks from gas and l .....

.... Not always have people been able to choose public transportation as a method of getting to and from. Dating as far back as 1889 when the first method of public transportation was developed in Massachusetts. Before this the thought of having a bus or train run to the main areas of a community was absolutely unheard of. But in today’s society there are many people who depend of the train or bus to get to work or to school or wherever it is they are going. When exactly did public transportation change from a luxury to a comfortable part of society? We can not exactly put a date on it but as you look back in time with me we ca .....

.... because scientists have never realy wnt in great deepth , because fungi are not needed commericaly. the ancestors of fungi lived in shallow bodies of water about 600-800 million years ago. Some of the things the fungi had to encounter from living out of water was, there was more sunlight that was normally blocked be the water, and the had to do something about the rapid shifts in tempature and seasonal shifts. Fungi are different from other plants in many ways. The general characteristics of fungi are extracellalar digestion, peculiar structures, growth patterns, their use of spores for reproduction, and their life cycles. Ch .....

.... helps remove carbon dioxide from the atmosphere via photosynthesis. For thousands of years, all good paints and varnishes were made from an oil from the plant. Today, it has almost been totally replaced by chemically derived oils. In closing, it is estimated that if just 6 percent of all our farmable land were seeded with this plant, it could supply us with all our fuel, gas and oil needs. I find it funny that government officials don't realize the impact that this single plant could have on the world. Instead of penalizing people for growing it, governments should be encouraging farmers to grow it. What is this plant you might .....

.... Third Edition, 1992). A radioisotope is a naturally or artificially created isotope having an unstable nucleus that decays, letting off alpha, beta, gamma rays until stability is reached (The America Heritage Dictionary of the English Language, Third Edition, 1992). Radon's melting point is -71°C. The boiling point is -61.8°C. Radon is the densest gas known (Concise Columbia Encyclopedia, 1995). Radon is a heavy, colorless, odorless, tasteless, non-flammable gas (therefore it cannot be detected with the human senses) produced by the radioactive decay of radium, which is itself a product of uranium. Radioactive mea .....
