GMOs have a ton of pros and cons, so it's hard to say. Although, I personally would like to avoid them. With the amount of people who have gone gluten free, there's more of a reason for it than being a hipster or a yuppie. Because the demand for wheat is so high, we had to genetically modify it. Although this increased its abundance, a lot of humans' digestive systems haven't evolved with it. That is the reason why it makes so many people sick, because they cant digest it. If the rate at which GMOs are being created and nourished continues, it's likely our digestive systems will reject it, possibly causing famine due to the inability to eat our own food.<span />
