According to the USDA’s Economic Research Service, 80 percent of all corn grown in the U.S. today is genetically engineered.(4)
Genetically modified crops present several environmental challenges. For one, the technology can’t be contained. For example, unless we isolate the corn crop, we can’t be 100% sure to prevent drift. Wind carries pollen that can contaminate fields miles away from the source.
Second, new research (7) shows genetically engineered crops require greater application of pesticides and herbicides compared to conventional crops due to the development of resistance.
Third, according to the Harvard Medical School’s report, “Biodiversity: Its Importance to Human Health,” if we disrupt biodiversity or narrow the range of crops we depend upon for food, we become more vulnerable to the loss of any one crop. (8)
