Extracts from this document...


May 27th , 2002 Pesticides in Our Environment - The Risks and Benefits Intro: Pesticides are useful and at the same time harmful. Thesis: By their very nature, most pesticides create risks to humans, animals, or the environment because they are designed to kill or otherwise adversely affect living organisms but at the same time, pesticides are useful to society because of their ability to kill potential disease-causing organisms and control insects, weeds, and other pests. Paragraph 1: History of pesticide regulation in Canada * 1969 - Canada's pest control products act (PCPA) passed. * 1987 - Law reform commission recommends 23 improvements to canada's pesticide law. * 1990 - Blue Book recommends major reform of pesticide legislation. ...read more.

* Children are more likely to play on treated floors and grounds. Unwashed hands often find their way to the mouth or to unwrapped snacks. * Because many pesticides (poisons) are heavier than air, children's breathing areas are likely to have higher pesticide (poison) concentrations. * Children may not read, understand or pay attention to warning signs. * A child's biology is different. Their immune system is less developed and may be less protective. * Developing cells are more easily damaged than cells that have completed development. During the rapid growth period of childhood, cells divide very quickly, making it more likely that a cellular mutation will be reproduced, thus initiating cancer. * Because they are younger, children have a longer life span ahead of them for chemically induced health problems to progress. * Small doses of neurotoxins can drastically impair the learning process in children. ...read more.
