Tastier salad greens and heat-resistant cattle. These are products of genetic engineering that can help our food system be more efficient and sustainable, says Beth Ellikidis, vice president of agriculture and environment with the Biotechnology Innovation Organization. BIO represents about 1,000 stakeholders in genetic engineering, including companies, states, and colleges that dabble in everything from pharmaceuticals to seeds. She says the exact science of GE can bring a lot of value to the food sector. Lynn Finnerty, senior director of public affairs, says the benefits aren't always embraced by U.S. trade partners. Mexico, for example, is turning away from biotech corn. The EU has also been hesitant. However, Finnerty sees optimism ahead.
