.... the islands. Now there are less than 200. The sugar cane fields in Hawaii became the breeding grounds for rats. Farmers released mongooses to kill the rats. They also began to eat the nene chicks and eggs. Roy Blackshire runs a program that places captive born nenes into the wild. This program, once a success, is now causing chaos in the nene population. A single pair of nenes were taken from the wild and bred in captivity. Later two more birds were added. The chicks were released into the wild and the program continued. Though there are several dozen nenes released from captivity, there is still little increase in the wild population. The inbreeding between birds is ....

.... keeps itself warm enough for humans to live on it. The only problem with this is that humans enhance the process even more. Over the past 200 years the emissions of greenhouse gases have been increasing due to the increase in technology that humans have developed (example, factories). These human-induced gases include carbon dioxide, methane, nitrous oxide, and ozone depleting substances such as CFCs, also known as Chlorofluorocarbons, hydrofluorocarbons, and perfluorocarbons. These gases are generated a number of human activities such as fossil fuel combustion, waste disposal in landfills, the use of a refrigerator, numerous agricultural and industrial activiti ....

.... development of the new theory [Shaw et al., 1984]. The sheet flood flows proposed for this area by Shaw et al were about 150 km wide, and the total volume of the meltwater reservoir was estimated as about 84,000 km3. The subglacial flood hypothesis for drumlin origin has been applied to drumlins in New York, southern Ontario, the northeast shore of Georgian Bay in Ontario, and to the interpretation of hummocky terrain in southern Alberta, and other areas, by various workers. Shaw suggested as many as 10 meltwater discharges, similar to those which caused the Livingstone Lake drumlins, would be needed to account for drumlin fields in other areas [Shoemaker, 1995, p. 3]. The ....

.... because that is what evolution is, a science. Although to truly understand evolution in its fullest context, one must not look to a dictionary, for dictionary definitions just are too vague. One of the most respected evolutionary biologists has defined biological evolution as follows: "In the broadest sense, evolution is merely change, and so is all-pervasive; galaxies, languages, and political systems all evolve. Biological evolution ... is change in the properties of populations of organisms that transcend the lifetime of a single individual. The ontogeny of an individual is not considered evolution; individual organisms do not evolve. The changes in populations that are ....

.... the Dandenong ranges in Victoria and karri from southwestern Western Australia grow to over 80 metres in height. Around Sydney Harbour, blackbutts once grew as big as a large lounge room Eucalypts seem to be able to grow anywhere. They are found springing out of large cracks in rocks, growing at the edge of sandy dunes in the full force of sea gales, and bent and twisted at the edge of the snow line in the Alps. They are also found in other parts of the world from Ethiopia to Ecuador, from California to Israel. Where eucalypts grow is determined by many environmental factors such as soil type, amount of water, wind direction, the direction the tree is facing and whether ....

.... a bit of water to wash the formaldehyde, alcohol solution from the specimen 5) we used tweezers to pull the mouth parts and head from the specimen. 6) we used a light so that we could see all the internal parts to the grasshopper clearly. I found this to be a very educational experience not just for me but for my whole group, I know this because I could see them concentrate and do everything right instead of just screwing off and not concentrating at all. I never knew that a grasshopper had so many complex parts to it. The jaw alone amazed me. I must say that the temperature in the room made those little things stink like a son of a gun. But all in all it ....

.... 20-30 MJ/kg of heat energy while uranium, in a fast breeder reactor, produces more than 24,000,000 MJ/kg (Energy 27). Those numbers alone are astounding. Uranium is also abundant, thanks to recent discoveries of large reserves. At present, uranium is only being mined and separated from ore. However, a huge untapped source is our oceans. Sea water contains 3.3x10^(-9) (3.3 parts per billion) of uranium, so the 1.4x10^18 tons of sea water contains 4.6x10^9 tons of uranium. All the world's electricity usage, 650GWe could therefore be supplied by the uranium in sea water for 7 million years(Energy 25). This is a only a theoretical number because it is not possibl ....

.... how quickly the ozone depletes. The main problem with the decaying ozone layer consists of people being careless. Many times, the chemicals released into the air by people drift into the ozone and form harmful chemical bonds with ozone molecules. One example would be chlorofluorocarbons or CFC's. CFC's were commonly found in spray cans during the early 1970's but were invented in the 1920's. They contain chlorine, fluorine, and carbon atoms which all form bonds with the rare ozone molecules. A few more products with CFC's are coolants for refrigerators and air conditioners, foam products, such as cups, and insulation for houses. Considering that oz ....
