Genesis

1. Pest-an organism that causes problems to humans or an ecosystem. Pesticide-a chemical poison that is used to kill unwanted organisms. The difference between chemical pesticides and biological pesticides is that chemical pesticides are chemicals that are used to kill a pest and a biological pesticide is a natural way such as an organisms predators to get rid of pests.

2. There are many pros in which the use for pesticides is useful. For example, pesticides get rid of organisms that are hurting a farmers crops such as corn. Another use is it can also prevent certain diseases from entering into a human's body. Lastly, pesticide use is also good because it made it possible for humans to succesfully replace natural ecosystems with farmland, lawns, golf courses, and gardens. Just like there are many useful ways to use pesticides, there are also manhy cons to them. One of the reasons is when a pesticide is sprayed on a crop it is estimated that only 10%, or even less, of the chemical spray actually comes in contact with the insect pests that are being targeted. Pesticides often destroy not only pest organism, but also their natural predators. Lastly, other beneficial organisms such as honeybees and other organisms that help pollinate flowering plants, may also be destroyed by pesticides.

3. There are quite a few ways to control pests while also safeguarding the environment. For example, autocidal control is when the insect actually contributes to its own population control. One type of autocidal control involves sterilizing males of a pest areraised in the labratorywhere they are exposed to radiation that renders them incapable of producing viable sperm. Another type of control is integrated pest management. This is a system that uses biological, autocidal, and cultural controls along with chemical pesticides to manage the size of pest populations. Lastly, biological control is preserving the natural predators living in an infested area or introducing new predators into the area.
