Pesticides A Killer

In “A Fable For Tomorrow,” Rachael Carson describes how deadly the pesticides can be to us all. Many pesticides are used to kill unwanted weeds and bugs that are found on the food or land. One method of spreading pesticides is to drop them on the land. This is called a spray drift. Carson says, “A grim specter as crept upon us almost unnoticed…”(155). Pesticide particles are not seen by the naked eye. They are so small that they can pass through the air unseen. Some pesticides used are harmful to the environment as well as humans and animals. Organic food is the safest for everyone. It is pesticide free.

There are a number of different pesticides: biopesticides, chemical pesticides, and antimicrobials. Pesticides are named according the type of pest they control. Organophosphate pesticide is a chemical pesticide that effects the nervous system and is very poisonous to insects and humans but not to the environment so much. Carbamate pesticides also affect the nervous system. There are many subgroups within carbamates. Organochlorine insecticides were used before but were removed because of health and environmental effects. Pyrethroid pesticide is a synthetic version of the natural pyrethrin pesticide; this also affects the nervous system. Carson states, “A white granular powder still showed a few patches; some weeks before it had fallen like snow upon the roofs and the lawns, the fields and streams”(154). I believe she is talking about the organochlorine insecticides. Biopesticides are formed from natural materials such as animals, plants, bacteria, and certain minerals. There are three classes of biopesticides. One is microbial pesticide; this is made from microorganisms. Some fungi control weeds and some kill specific insects. Another class of biopesticide is plant-incorporated-protectants. Plants produce this from genetic material that was added to the plant. The last is biochemical pesticide, this kind naturally occurs to control pests by non-toxic mechanisms.

Carson describes, “In the town the doctors had become more and more puzzled by new kinds of sickness appearing among their patients”(154). Many pesticides used are very harmful to humans and animals. What would happen if pesticides were not used to control insects? The food will become infested with insects and funguses that would end up ruining the products. Pesticides are also used to treat plants and grass from insects. I was thinking that the grass used at parks where children play should not use pesticides. But then I wouldn’t want my children to be bitten by an insect that ...
