15. Reduced biodiversity
One of the main concerns when it comes to genetically modified organisms is biodiversity. As we plant more and more genetically modified plants, we abandon traditional ones. Not only is that bad for the environment, but for humans as well. As we grow more dependent on just a few plants for our diet, we expose ourselves to the risk of a new disease that could wipe them out. And if you think this is farfetched, think again. It has already happened in our history. Perhaps the most known example happened in Ireland in the 19th century. A large majority of the population was depending on the potato for their nutrition and when sudden blight wiped out the harvest, creating one of the worst famines in modern history.
