Business is the activity of making one's living or making money by producing or buying and selling goods or services. Simply put, it is "any activity or enterprise entered into for profit. It does not mean it is a company, a corporation, partnership, or have any such formal organization, but it can range from a street peddler to General Motors." The term is also often used colloquially (but not by lawyers or public officials) to refer to a company, but this article will not deal with that sense of the word.
Pesticides are used around the world but can persist in the environment, contaminating drinking and irrigation water with toxic organic compounds. One example is Vietnam where herbicides and dioxins applied during the Vietnam war entered the water cycle, possibly leading to cancers and abnormalities in newborn babies.
