Antibiotic Resistance

Antibiotic resistance (or pesticide resistance) refers to the ability of a species, or certain individuals within a species, to survive in the presence of a chemical or other treatment due to adaptation and development of tolerance of a product through natural selection. Resistance occurs as a result of overuse of a product, especially at low doses over long periods of time, which is common on factory farms where antibiotics are added to feed and in monocultures where pesticides are used over large expanses of land for many years.
