question 315

Multiple Choice

GMOs
GMOs, or genetically modified organisms, are organisms whose genes have been altered in laboratories. Scientists modify the genetic codes of plants or animals by inserting copies of desirable genes into the organism's DNA. While modifying organisms in a laboratory is a relatively new scientific development, people have been experimenting with genetics on plants and animals for centuries. For example, cattle ranchers have selectively bred their animals to produce cows that give more milk.
Although some people fear the "Frankenstein" nature of GMOs, there is no scientific evidence to suggest that GMO-based foods are harmful for human consumption. In fact, there are several reasons to believe that GMOs actually quite beneficial.
Through genetic modification, scientists can breed species of plants or animals that yield hardier, more abundant, or even more nutritious food. Geneticists have been able to produce rice plants that can survive droughts and wheat plants that are naturally pest-resistant. Some genetically modified foods have been engineered to have higher levels of specific nutrients, such as protein or calcium. Proponents of GMOs argue that these kinds of advances might one day help to end world hunger. Furthermore, genetically modified crops and animals can be bred to require fewer natural resources and produce less waste. This means that GMOs might also be better for the environment.
