Weed

Weed is the generic word for a plant growing in a spot where it is not wanted. The most prominent use of the word is in connection with farming, where weeds may damage crop?s when growing in fields and poison domesticated animals when groing on pasture? land.

In order to reduce weed growth many strategies have been developed. The most basic is ploughing, which cuts the roots of annual weeds. In modern times, chemical weed killers have caused environmental damage, and efforts are being made to reduce the use of such substances (see for example [genetic engeneering]?).
