Biotech companies tell us that genetic engineering will provide insurance against growing demands on our food supply, but scary questions remain.

Choosing sustainable agriculture over genetically engineered crops. Sustainable agriculture, not genetic engineering, may be the answer to the world’s growing food needs.

Choosing Sustainable Agriculture Over Genetically Engineered Crops

The recent spike in food prices, as well as concerns about what the future may hold, are weighing on the minds of people across the globe. The biotech industry is exploiting such worries and claiming, contrary to evidence, that genetically engineered (GE) crops must be accepted to help the world feed itself. The industry hopes to use these scare tactics to expand into the many countries, especially in Europe and the East, that have wisely rejected GE foods because their human health and environmental safety have not yet been assessed.

After 20 years of research and 13 years of commercialization, GE crops have a track record that allows us to evaluate their performance. So far, there has been little progress in achieving important goals such as increased yields, better stress (drought) tolerance and improved sustainability in the form of decreased need for fertilizers, tilling and pesticides. Moreover, food safety and environmental risks from genetic engineering also remain to be addressed.

The most widely grown genetically engineered crop in the United States, herbicide-tolerant soybeans, has not increased yield above its conventional counterparts, based on U.S. Department of Agriculture (USDA) trend data and numerous field studies. Insect-resistant GE crops have sometimes indirectly improved yields, but such yield increases have been modest, and recent studies suggest that much of the apparent improvements may instead be due to advances in conventional breeding. New insights from our growing knowledge of crop genetics are improving these conventional breeding techniques — without genetic engineering.
