Super crops lead to Super weeds

It has been confirmed by American scientists that genes from super crops can migrate to near weeds, which then makes the weeds stronger and resistant to the weed killer being used. This has been proven in three states in America from a Sunflower which has been modified with an artificial gene to ward of pests, this ability can then spread on to wild sunflowers close by. "This is the first example of what might happen if a beneficial transgene accidentally spread to a wild population and then proliferated in subsequent generations," said study co-author Allison Snow, a professor of evolution, ecology and organismal biology at Ohio State University. "We were surprised that a single transgene (foreign gene) could have such a big effect on seed production."

These weeds are created through the process of Hybridization which is the mixing of plants genetic material. This is the same process farmers use to create ideal seeds for the crops which is called plant breeding

Once the artificial gene has moved into other plants, it cannot be controlled, thus there will be no more pure seed. This has been proven as a farmer cannot grow canola plant anymore as he cannot prove that the seeds are not Monsanto's altered canola seeds, which is impossible as farmers have found that all seeds have been contaminated. The super weed problem has happened over the last two to three years. Some counties such as France have put in place barriers or a safe isolation distance between GMO's and ordinary plants. This is used so that there will be no cross contamination between artificial plants and normal plants.
