What are some of the pros and cons of genetically modified foods? One of the most controversial topics in food today is genetically modified foods (GMOs). GMOs are plants or animals that have been created through gene splicing, a process where genes from one species are inserted into another.

This creates combinations of plant, animal, bacterial, and viral genes that do not occur in nature or through traditional crossbreeding methods. GMOs were first introduced into the food supply in the 1990s and their use has continued to grow. In 2015, 88% of corn planted in the United States was GMO corn.

Other GMO crops include soybeans, cotton, canola, alfalfa, sugar beets, papaya, squash, zucchini and yellow summer crookneck squash. These crops have been engineered to be resistant to herbicides and/or pests. For example, Monsanto’s Roundup Ready crops are designed to withstand applications of glyphosate (the active ingredient in Roundup), while Bt crops contain a protein that kills certain insects when they eat the crop.

There are several reasons why farmers choose to grow GMOs. One reason is that they can achieve higher yields because the crops are more resistant to pests and weeds. This means farmers can use fewer inputs like water, pesticides, and herbicides.

Genetically modified crops also tend to have a longer shelf life than non-GMO counterparts due to their resistance to mold and rot. Farmers growing GMOs can also take advantage of technology like precision farming which helps them target specific areas with inputs like fertilizer based on GPS data collected by satellites or drones.
