.... people who work with livestock or in other businesses where workers must handle animal carcasses. The livestock version of the vaccine is very effective, however. The vaccine for both animals and humans is composed of sublethal amounts of toxin that induce formation of protective antibody. Frequent boosters are necessary to maintain resistance to Anthrax. Bacillus Anthracis spores also may live in soil for years. The only way to destroy the spores is by steam sterilization or burning. There has been no evidence of person to person transmission of the disease, th .....

.... characterized by the parallel arrangement of their mineral layers or beds, which are distinguished from each other by differences in thickness, the size of the grains, or color. All rock disintegrate slowly as a result of mechanical weathering and chemical weathering. Mechanical weathering is the breakdown of rock into particles without producing changes in the chemical composition of the minerals in the rock. Ice is the most important agent of mechanical weathering. Water percolates into cracks and fissures within the rock, freezes, and expands. The force e .....

.... the North Atlantic. Although hurricanes are most noted for their destruction, some parts of the world, especially eastern Asia, rely on them for much of their precipitation. Although numerous tropical storms develop each year, only a few reach hurricane status, which by international agreement requires wind speeds in excess of 119 kilometers per hour and a rotary circulation. Hurricanes average 600 kilometers in diameter, and often extend 12,000 meters above the ocean surface. From the outer edge of the hurricane to the center the barometric pressure has on .....

.... reactions. Rainwater, snow, fog, and other forms of precipitation containing those mild solutions of sulfuric and nitric acids fall to the earth as . Water moves through every living plant and animal, streams, lakes, and oceans in the hydrologic cycle. In that cycle, water evaporates from the land and sea into the atmosphere. Water in the atmosphere then condenses to form clouds. Clouds release the water back to the earth as rain, snow, or fog. When water droplets form and fall to the earth they pick up particles and chemicals that float in the air. Even cle .....

.... integrity and that the application of such technology will result in undesirable shifts in our view of how we may treat animals and how radically we can meddle with nature in general. Furthermore, it is stressed that, whatever potential uses it may be put to at some future stage, the technique raises a long string of ethical problems. In addition, it may be feared that within a number of years the development and application of animal techniques will lead to the testing, development and application of human . Though this notion seems very unlikely to occur .....

.... identical to pancreatic human insulin. (Hyde, 1984) As of 1986, human insulin began to be produced by a process which involves the enzymatic conversion of human insulin's biosynthetic precursor, human proinsulin. The genetic coding for human proinsulin is inserted into the special E. coli bacteria which are then grown in a fermentation process to produce human proinsulin. With genetic engineering, new proteins are synthesized. They can be introduced into plants or animal genomes, producing a new type of disease resistant plants, capable of living in inhospitab .....

.... to describe the earth. This “mixing bowl” that is our earth is constantly being manipulated to create the perfectly balanced “mixture” (Huber). Since there will never be a perfect balance or “mixture”, what is the point of even trying? Maybe they are right in saying that we will never find the perfect mixture, but this negative attitude is part of the problem. Nothing will be accomplished unless we reject apathy and negativity. One writer, T.H. Watkins, has criticized the idea of putting a “price tag” on the earth. He thinks that it is wrong to assign a .....

.... in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very 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 i .....
