You do it every day, and most don’t even think about it: You eat. Why? Because you’re hungry (or, let’s be honest, because you’re bored — I do it, too). That’s about as far as the analysis goes. This way of food consumption has a lot of consequences, but one you might not realize is that you’re eating thousands upon thousands of “genetically modified organisms.”

When you eat chips, pizza, fro-yo and fries, you’re eating some genetically modified organisms.

A genetically modified organism (GMO) is a plant, animal or microorganism whose genetic code has been altered, subtracted or added to (either from the same species or a different species) in order to give it characteristics that it does not have naturally.

There is no denying that there are some great possible positive outcomes of embracing genetically modified stuff (eradicating world hunger, new vaccines, biofuel research, etc.), but one also can’t deny that there are proven negative outcomes to switching over to GMOs.

In terms of our health, genetically engineered foods have not been shown to be safe to eat and may have unpredictable consequences. How these new strains of bacteria may affect our body systems’ balance is anybody’s guess. We know a little about how GMOs affect our minds, though: When we consume GMOs, the chemicals in GMOs upset the dopamine-serotonin balance in our noggins. The more GMOs you eat, the less happy you become.

Genetic engineering reduces genetic diversity. When genes are more diverse, they are more robust. Plants with reduced genetic diversity cannot handle drought, fungus invasions or insects nearly as well as natural plants, which could have dire consequences for farmers and communities dependent on GMO crops for survival. Due to that, GMO crops require massive amounts of pesticides, herbicides and fungicides. Plus, once the mutant genes are out of the bag, there is no going back. Genetically modified organisms contaminate existing seeds with their altered material, passing on modified traits to non-target species.

Finally, one of the greatest arguments in favor of GMOs is that of ending global starvation. GMO crops are made to grow in great numbers in less space and withstand greater conditions than normal crops. However, genetically engineered crops have shown no increase in yield and no decrease in pesticide use, and in many cases, other farm technology has proven much more successful.

Basically, think about what you eat — where it’s coming from, what exactly it’s made of and tell GMOs to “GTFO.”
