Lawn Pesticides and Chemicals
Recently, the use of lawn pesticides and chemicals has grown enormously with home owners and golf course management in hope of attaining "the perfect turf." However, the negative effects that are associated with attaining ones "dream turf" is primarily caused by the direct use of pesticides and chemicals. The chemical pesticide industry fails to address these issues and has made every effort to keep this information from the public.
Herbicides and pesticides are not a natural way to achieve a beautiful lawn, contrary to what lawn care companies would like people to believe. They are broad-spectrum biocides, and by their very nature can harm organisms other than the targeted species (Dieglman, 1996). Pesticide industries make false claims by stating that their chemicals are heavily diluted, failing to mention that toxins are still extremely dangerous in small amounts. Other false claims include companies like ChemLawn which state that a child would have to ingest ten cups of treated grass clippings to equal the toxicity of one aspirin. In fact, the real danger is not from grazing the lawn. Most poisonings come from inhaling pesticide residues or absorbing them through the skin (Begley, 1988). These chemicals include wartime defoliants such as Agent Orange, nerve-gas type pesticides, and artificial hormones (Dieglman, 1996). In some instances, pesticides like DDT, which remain active for many years, accumulate in our bodies and are released at potentially toxic levels. In women, lifetime exposures to such chemicals are released in the breast milk of her firstborn child (International Joint Commission, 1990).

The rhetorical occasion of this excerpt is to inform others about the dangers of chemicals on earth’s vegetation and animal life.
My initial observation was that simple conservation actions such as reducing the use of pesticides can achieve measurable improvements in habitat quality and environmental health. Herbicides are toxic to most mammals as well as to the beneficial insects that you want to encourage in your garden. Sometimes herbicides seep into the ground water; causing contamination of which the long term effects are not known. Herbicide application can also result in drift or movement in the soil, this endangers wanted vegetation nearby. Herbicides are used far too rampantly. Excessive use of toxic herbicides is used when not necessary and because most are not aware of the many other natural alternatives. We must find more ways to cut back on the use of chemical herbicides and change to biological weed control methods.
The pesticide DDT banned in 1987 was a detrimental to the environment leading to it to be banned in 1987. DDT remains in the soils for a long period of time. The chemicals affect the ecology of the soil and water run off causing contamination of livestock and native animals and aquatic species. Studies indicated a range of human health impacts from DDT including cancers, infertility, miscarriage and nervous system impairment. The social and economic impact of DDT use in viticulture was significant.

Tourism impacts can be generally classified into seven categories with each having both positive and negative impacts. These impacts include; economic, environmental, social and cultural, crowding and congestion, taxes, and community attitude. It is essential for a balance on array of impacts that may either positively or negatively affect the resident communities. Different groups are concerned about different tourism impacts that affect them in one way or another. Tourism’s benefits can be increased by use of specific plans and actions. These can also lead to decrease in the gravity of negative impacts. Communities will not experience every impact but instead this will depend on particular natural resources, development, or spatial patterns (Glen 1999).
Evidence provided to support these claims of human and wildlife harm is largely from laboratory studies in which large doses are fed to test animals, usually rats or mice, and field studies of wildlife species that have been exposed to the chemicals mentioned above. In laboratory studies, high doses are required to give weak hormone activity. These doses are not likely to be encountered in the environment. However the process of bioaccumulation can result in top-level predators such as humans to have contaminants at levels many million times greater than the environmental background levels (Guilette 1994). In field studies, toxicity caused by endocrine disruption has been associated with the presence of certain pollutants. Findings from such studies include: reproductive disruption in starfish due to PCBs, bird eggshell thinning due to DDT, reproductive failure in mink, small penises in alligators due to DDT and dicofol (Guillette 1994, Colburn et al 1996). In addition, a variety of reproductive problems in many other species are claimed to be associated with environmental contamination although the specific causative agents have not been determined. One recent discovery that complicates the situation is that there are many naturally occurring "phytoestrogens", or chemicals of plant origin that exhibit weak estrogenic properties.
Civilization began with agriculture, and agriculture continues to be an integral part of our lives. Civilization brought knowledge, knowledge brought technology, and technology brought chemicals and pesticides to “improve” our world. “The Obligation to Endure” is an excerpt from Rachel Carson’s “Silent Spring,” a passionate and masterful work on the results of civilization’s efforts to control pests and insects. These effects include destruction of the environment, alteration of gene structures in plants and animals, water contamination, and an upset of nature’s delicate balance. This article is an impassioned plea to the world to understand the threat and demand the information necessary to make an informed consent on use of these deadly substances.
“The issue of growth in the travel industry - how much, how fast, what kind - is crucial to the future of communities, local lifestyles and cultures, and the natural environment. There are a variety of instabilities and inequities associated with the expansion of tourism. If the social costs of infinite growth (human consequences of ecological pollution, centralized concentration of power, inequitable income distribution) are as high as they appear to be, our current social systems cannot support such growth indefinitely. Tourism remains a passive luxury for thousands of travelers. This must change” (Rethinking Tourism and Ecotravel by Deborah McLaren, 1998, p. 6).

The protection of the environment however has just recently become the major issue that it is in today’s society. People worldwide have slowly begun to realize and become aware of the blatant destruction and deterioration of the environment and ozone. As well as the consequences and side affects, that we, as a society have created. The majority of people are just becoming aware of the frightening reality of the situation. As society becomes more informed on the issue of the environment, they too become more impatient, and feel that in the snap of fingers, the damage can be reversed and future damage can be stopped instantaneously.
