(genetically modified) seeds. In fact a significant amount of seeds cultivated are from this source. There are two main reasons why genetically modified crops are grown they are tolerant to herbicides and resistant to insects.Weed control is supposed to be easier because the plants are able to tolerate non selective chemicals which kill all other natural vegetation. Unfortunately this has resulted in a decrease of beneficial insects as the plants that they feed on are also killed. The plants are resistant to insect pests as they have bacteria introduced within the plant by genetic modification which kills insects that feed upon them. It had been predicted that G.M. cotton crops would require less herbicides but this does not appear to have happened. It has been suggested that environmental effects require further studies.
