199.35 Evolution Versus Creationism.
This paper gives the viewpoint of evolution versus creationism. Biological evolution or evolutionary biology is genetic change in a population occurring from generation to another (O'Neill 2002). All life forms evolve and continue evolving from earlier species, and these life forms include human beings. Most biological scientists concur that the earliest life forms on earth evolved from chance natural occurrences 3 1/5 to 4 billion years ago. They agree that evidence for evolution comes from fossil records of change, the chemical and structural similarities of related life forms, the recorded genetic changes in living organisms for many generations (O'Neill) and the geographic distribution of these related species. In effect, this Supreme Court ruling could neither prevent public schools from teaching the creation theory nor ban the teaching of the evolution theory. Both subjects are taken off the standard tests of public schools, and the local school board decides what should be taught (youdebate.com).

200.91 Air Pollutants.
This paper is on the topic of air pollutants. Air pollution pertains to substances and gases in the air that threaten health and life. Among these are pollutants and irritants, such as nitrogen oxides, sulfur dioxide, and carbon dioxide; particulates, volatile organic compounds (VOCs), toxic substances and some natural substances, like pollen. But most of the pollution comes from the by-products of industrialization - fossil fuel combustion, transportation, transportation, power plant emissions and those from other industrial processes. The burning of fossil fuels to generate electricity alone is the greatest source of air pollution in the USA. These outdoor pollutants can undermine health and cause environmental disturbances, such as acid rain, and are toxic.

201.259 Pollution and Its Effects on Wildlife.
As a result of pollution caused by humans, wildlife populations are confronted with a bewildering array of pollutants that we release into the environment either by intent or accident. This paper will describe several human-induced pollutants and their effects on wildlife. Pollution is one of the primary ways in which humans have caused drastic modifications of wildlife habitat. Historically we have regarded the air, water, and soil that surround us as waste receptacles and have given little consideration to the ecological consequences of our actions. As a result, wildlife populations are confronted with a bewildering array of pollutants that we release into the environment either by intent or accident.

202.268 Reforestation.
This paper discusses reforestation. Reforestation can certainly be argued over, but almost everyone will concur with one idea: More forests equal a better environment for us all. Only it doesn't stop there; there are too many considerations, too many variables to take into consideration. Thus, we are brought back to the original question: Does the world really need more forests? America's richly, diverse forests provide vital products and amenities to our society. "Through scientific management, sustained production of pulpwood, saw timber, veneer, poles, and chemical by-products is possible from our forests." (Gallegos, 1982) Our nations forests provide important values to us including: quality habitat for wildlife, biodiversity of plant and animal communities, clean water, aesthetic benefits and recreational opportunities.

203.420 Sediments.
This paper discusses sediments and what they are, where they are found, and the different categories of them. Sediments are particles that accumulate on the ocean floor. Sediments fall into three distinct categories: lithogenous, biogenous and hydrogenous. The overall volume of each category varies from place to place within the ocean basin, and is distributed as a function of deep ocean currents, prevailing wind patterns and local volcanism.
