pesticides

Pesticide use is a significant global issue today because almost three million tons of pesticides are currently used worldwide, and wherever there is farming, there is pesticide use. (Fairley, 2001) Pesticides can include the following varieties: bactericides, baits, fungicides, herbicides, insecticides, lures, rodenticides, and repellents. All of the above pesticides are any substances or mixtures of substances used to destroy or alter the life cycle of any pest. (Encarta, 1996 ed.) They work by physically, chemically, or biologically interfering with a pest’s metabolism or normal behaviour. Although some agricultural experts oppose implementation of alternative methods of pest control because food production will greatly decrease, alternative methods of controlling pests should be implemented because food production will be maintained, drinking water safety will improve, and overall human and animal health will see a positive outcome.

Of course, though, some agricultural experts oppose implementation of alternative methods of pest control because food production will sharply decrease. Some researchers feel that the risks of eliminating pesticides are much greater than the risks of pesticide exposure. Banning or res


tricting pesticides would hurt the poor far greater and would severely raise prices on fruits and vegetables. As research shows, some agricultural experts oppose implementation of alternative methods of pest control because food production will sharply decrease.

Of utmost importance, the overall health of humans and animals will see a positive increase with the extinction of pesticide use. In developing countries, an estimated ten percent of fatal injuries can be attributed to pesticide use. (Fairley, 2001) When extensive pesticide use is present, an increase in birth defects can consequently be observed. In fact, studies have shown that illness was higher in people who had extensive exposure to pesticides. Negative effects of such exposure can include: eye irritation, drowsiness, weakness, visual failure, and sweating. In addition, various chronic problems can occur in humans. Such problems can include: cancer, reproductive disorders, and immunological disorders. Parental exposure to pesticides has been linked to birth defects in babies. However, humans are not the only creatures who feel the wrath of pesticide use. Animals are even more vulnerable to the toxins found in pesticides. Pesticide chlorpyrifos is directly toxic to the brains of mammals. (Encarta, 1996 ed.) It can be found in numerous household products, including bug sprays and flea collars. Such toxins have been shown to adversely affect the developing nervous system of experimental animals. It is estimated that over three million people are poisoned from pesticides each year. In addition, 200 000 people lose their lives to pesticides annually. (Fairley, 2001) It is clear that pesticides are not just causing rare deaths, but have become a part of the environment. With such a high exposure to chemicals, it is no wonder as to why many f
