GMOs are organisms that have had their DNA modified through genetic engineering. This is often done by taking a gene from one organism and putting it into another one to alter it in a desirable way. For example, when genetic engineers want to create a corn crop that is resistant to pests, they seek out the trait in Bacillus thuringiensis (Bt) soil bacteria that naturally acts as a pesticide. From there, engineers isolate the gene responsible for that trait and directly insert it into the corn’s DNA. This corn is then bred with other corn until it’s ready to be produced for consumption.
Scientists adopted this process for altering food for a variety of reasons, but most commonly to create crops, like the corn, that can naturally keep pests away, as well as crops that are resistant to herbicides and can tolerate various climates for more sustainable agriculture. And this manipulation has proven to be a very divisive issue.
