... of species. Fire suppression has allowed forested areas to achieve a climax state which provides less forage for wildlife. While terrestrial wildlife is benefited by fire, aquatic ecosystems are negatively impacted by large fires through the increase in sediment flow. Fire is essential in maintaining biological diversity in the Northern Rocky Mountain forests. NEGATIVE EFFECTS - AQUATIC ECOSYSTEMS Contrary to the beneficial impacts of fire on terrestrial wildlife, aquatic ecosystems are negatively affected, such as the decrease in fish populations by fire. In the North Fork Shoshone River adjacent to Yellowstone National Park, fish died from increased sed ...
... what her captors looked like, but did remember that technological implants had been made, including audio-visual implants. The UFO entities can see through her eyes and hear through her ears. She is aware of the continuous presence of what she calls her "live-in companion," who answers to the name of Hweig. Mrs. Kannenberg realizes that Hweig would be explained away by conventional scientists in terms of split personality or some other form of mental abberation. Although she does not agree with this interpretation of her situation, she does not claim to have any paranormal abilities because of her contact with Hweig. She does not ...
... most notably the World Wide Web (WWW). With increased penetration of computers, particularly multi-media computers equipped with CD-ROM drives and modems, subscription-based services such as America Online (AOL), Prodigy, and Compuserve, where consumers are able to check airline flight schedules and make reservations, purchase a wide variety of products, and discuss product performance with other consumers, are becoming very popular. Households in Chicago and San Francisco can purchase groceries from home using computer software marketed by Peapod, Inc. This latter service allows consumers to search within a product category using attributes such as price ...
... U.S. Environmental Protection Agency (EPA) and demand they enforce pesticide regulations. With the assistance from other organizations such as the Senate Agriculture Committee (SAC), National Academy of Science (NAS), National Resources Defense Council (NRDC), and Consumers Union (CU), the EPA has made a notable progress. Throughout the years, consumers have pushed for research of the chemicals and substances that produce agricultural and what these do to our internal system. Congressman, James J. Delaney was also convinced that too many pesticide chemicals were found in foods. So in 1958, the House Select Committee investigated the use of chemicals in food ...
... have tripled, the global economy has quintupled and the world population increased twofold (Anonymous em_txt4.html). Richard Cromwell, general manager of SunLine Transit Agency in Southern California's Coachella Valley, is a firsthand proponent of alternative fueling. Having to smell the awful odor emitted day after day from his fleet of forty-seven buses, Cromwell (Silverstein 10) encourages the changeover. Phil Bostley, Mayor of Indian Wells, a subsection of Coachella Valley, agrees wholeheartedly by saying petroleum-base fuels will go the way of the buggy whips back in the 1930's (Silverstein 10). Fortunately, for those who run such fleets, a mandate issued ...
... spasms of extremities or even fainting”(Hayes 1). In some ways, it can be look on as a chain reaction. “It is often caused by new problems that worsen existing difficulties”(TWHSTSV 2). When one person sees another running about wildly and finds out what the cause is, he or she will do the same; until eventually the idea spreads to the entire population. Some problems that cause these are “overly strict regulations, lack of open communication between the authorities and the residents, as well as inadequate healthy recreational outlets”(Hayes 1). All these issues are things that if performed, can help prevent or calm an out ...
... in buildings.(5) Outdoor air contains radon, but it is in extremely low concentrations therefore it is not a health hazard. Some wells contain water that has radon dissolved in it. This can be a hazard if the water is agitated or heated, allowing the gas to escape and elevate the levels that are in the building.(6) Health Risk The Surgeon General's office reports that indoor radon gas is a national health problem. This gas causes thousands of deaths every year.(7) These deaths are a result of lung cancer, which is caused by the radioactive particles that make up the gas.(8) The likelihood of getting lung cancer from radon depends on: the concentration tha ...
... Cattle are also a major cause of desertification around the planet. Today about 1.3 billion cattle are trampling and stripping much of the vegetative cover from the earth's remaining grasslands. Each animal eats its way through 900 pounds of vegetation a month. Without plants to anchor the soil, absorb the water, and recycle the nutrients, the land has become increasingly vulnerable to wind and water erosion. More than 60 percent of the world's rangeland has been damaged by overgrazing during the past half century. Cattle ranching has also been linked to Global Warming. The grain-fed-cattle complex is now a significant factor in the emission of three of the ...
... in the Bubble disease." ADA deficiency is a result of inheriting two copies of the defective ADA gene. Possession of a normal gene leads to the continuous, regular production of ADA in cells throughout the body. Without at least one properly functioning gene, children have no way of converting deoxyadenosine (a waste product) into inosine. This leads to the rapid build-up of deoxyadenosine in the system, which becomes phosphorlyzed into a toxic triphosphate, which kills T-cells. The result is an almost complete failure of the immune system and early death. Previous treatment options included bone marrow transplants, which worked well with matched donors. A major ...
... medical use only until the 19th century when use of cannabis spread from China and the Middle East to the population of Europe and America. Since that time cannabis became illegal and very popular drug known in all countries. In some way the affects of the marijuana may be serious. When smoked, the effects of cannabis begin immediately. When eaten the effects can take 1 to 2 hours to begin, depending on how much food is in the stomach. The effect after smoking cannabis may last for 1-2 hours and when eaten, the effects may sometimes last longer than 4 hours. One of the primary effects of smoking cannabis is relaxation, and changes of mood. By taking low amou ...
