Genetically modified (GMO) foods have been in the headlines a lot lately. These foods have a gene inserted into them to help develop a certain characteristic, usually in relation to disease resistance or pests. Despite all the articles about these foods, it is hard to know what exactly the controversy is. What it all boils down to is one question: are GMO foods safe?
People who oppose GMO foods claim that they are not safe. One potential concern is that the food themselves are toxic and will harm humans. Another concern is allergies. Will a gene from a peanut inserted into another plant cause a reaction in someone allergic to peanuts?
Are the genetic changes going to result in other species dying out? There are few studies about this issue, and many of them are inconclusive.
