Taylor Sheridan English 201A Professor Jim West 15 May 2012 The Hidden Cost of Convenience Human beings have had a relationship with the Earth through farming since 10‚000 B.C.‚ and to this day humans remain dependent on that very relationship. The development in farming techniques has exploded since the early 1900’s with the development of chemical pesticides and Genetic Engineering (GE). GE crops treated with pesticides produce larger quantities of food at an immensely faster rate. Approximately

only 15 Km away from Cochin‚ the “Queen of the Arabian Sea ”‚ there is Eloor Island‚ home to Kerala’s largest industrial cluster. Eloor‚ an island of 11.21 sq/km‚ on the Periyar River is home to more than 247 chemical industries‚ including the only DDT-producing facility in India. Most of these units have been here for the last fifty years and use extremely obsolete and polluting technologies. Toxic pollution from heavy metals to chemicals and radioactivity is found in air‚ soil and in the Periyar

The Insecticidal Potential of Chili Pepper Leaf Extract Against Termites Abstract. The goal of this research is to determine the insecticidal effects of chili pepper leaf extract on termites. Chili pepper leaves were collected then air-dried and oven-dried until brittle. The leaves were then pulverized and milled using the Willey mill. After this‚ the powdered leaves were boiled in water and filtered. After the preparation of the extract‚ termites were gathered in two containers. One of the containers

Selection Genotype and Allele Frequencies We want to compare the results when the Natural Selection Genotype Viabilities are different. “AA” and “Aa” mosquitoes are resistant to DDT. This is a high Natural Selection Genotype Viability. The “aa” mosquitoes have a low viability; meaning they are selected against by the DDT environmental factor. The result is AA is exponentially growing Aa and aa are exponentially decaying 1) This is because A is the dominant Allele and “a” is affected so it

Wildlife‚ along with the human population is affected by environmental estrogens. Fish are affected by estrogens contained in DDT‚ a frequently used pesticide‚ and PCB’s‚ Polychlorinated Biphenyls. Scientific studies conducted on small animals such as frogs‚ produced bizarre defects such as additional extremities and the absence of eyes. (Cody 1998). Some species of frogs have
