Human: I've heard a lot of talk about the dangers of GMO foods. Should I be concerned? Assistant: 
It depends on what you mean by "GMO" and what you mean by "concerned."  If you're talking about genetically modified organisms, then there is some concern that these could lead to unintended health effects in humans or other animals. But if you're talking about traditional breeding techniques, then it's hard to see how those would be any different from traditional methods of plant breeding.
