</div></div><div class="section-body" id="section-1"><p>Genetic engineering can be done with plants, animals, or bacteria and other very small organisms. With genetic engineering, scientists take the gene for a desired trait in one plant or animal, and they insert that gene into the DNA of another plant or animal. Genes can also be moved from an animal to a plant or vice versa.</p><p>The process to create GMOs is different than selective breeding. This involves selecting plants or animals with desired traits and breeding them. Over time, this results in offspring with those desired traits. One of the problems with selective breeding is that it can also result in traits that are not desired.</p><p>Genetic engineering allows scientists to select one specific gene to implant. This avoids introducing other genes with undesirable traits. Genetic engineering also helps speed up the process of creating new foods with desired traits.</p><p>Genome editing is a newer method that involves adding, removing, or changing the DNA of a plant or animal in a targeted way.</p><p>The possible benefits of genetic engineering include:</p><ul><li>More nutritious food</li><li>Tastier food</li><li>Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer)</li><li>Less use of pesticides</li><li>Increased supply of food with reduced cost and longer shelf life</li><li>Faster growing plants and animals</li><li>Food with more desirable traits, such as potatoes that produce less of a cancer-causing substance when fried</li></ul><p>Some people have expressed concerns about GE foods, such as:</p><ul><li>Creation of foods that can cause an allergic or toxic reaction</li><li>Unexpected or harmful genetic changes</li><li>Inadvertent transfer of genes from one GM plant or animal to another plant or animal not intended for genetic modification</li><li>Foods that are less nutritious</li></ul><p>These concerns have thus far been unfounded. None of the GMOs used today have caused any of these problems. The US Food and Drug Administration (FDA) assesses all GMOs to make sure they are safe before allowing them to be sold. In addition to the FDA, the US Environmental Protection Agency (EPA) and the US Department of Agriculture (USDA) regulate bioengineered plants and animals. They assess the safety of GMOs to humans, animals, plants, and the environment.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Food Sources</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
