The cultivation of genetically modified food crops has been adopted for the last 15 years as the plants can be made tolerant to herbicides and resistant to incest.
But large scale use of GM crops over an extended period of time poses many dangers too. The genes that have been manipulated in the crops to achieve the desired traits can move to plants that are actually weeds and make them immune to herbicides. As weeds use the resources meant for the plants being cultivated it is essential to eliminate them. But with the tolerance against herbicides acquired by them it becomes very difficult to get rid of them. Newer, more potent herbicides are required that can harm the corn plants along with the weeds.
It is therefore very important to carefully consider both the cons as well as the pros of growing GM crops. Scientists now recommend a reduced use of GM plants and the adoption of alternative natural ways instead to deal with problems like weeds and pests.
