Check out the Non-GMO Shopping Guide for more information on GMO’s and how to buy non-gmo foods.
Genetically Modified Seeds were originally created to obtain higher yields, to create seeds resistant to pesticides and to obtain other factors that would allow growers to produce “better” crops. However, studies have linked genetically modified organisms with an increase in allergies, such as with genetically modified soy beans.
Another issue surrounding GMO’s is the control that large agribusinesses have. For example, Monsanto (a large agribusiness) sells roundup, but they also sell corn seeds that aren’t killed by roundup. Monsanto then controls the seed industry for this corn by engineering seeds that can’t be reused year after year.
There is a fear that genetically modified seeds will cross pollinate and contaminate regular seeds, depleting the supply of non-GMO seeds. There are no extensive studies on the long term effects of GMO’s, so if there are negative effects, this could be a problem.
