Let’s make something clear right here, at the beginning of the article–there is a vast amount of legitimate scientific literature that describes evidence that GMO crops are safe to both human health and the environment.
In the world of scientific research, the absolute highest quality evidence are meta reviews, which are methods to contrast and combine results from a wide swath of peer-reviewed studies which may be useful in identifying patterns, sources of disagreement and other relationships. Since meta reviews combine the results from a larger number of studies, they can be more statistically significant.
Last year, a team of Italian researchers published one such meta review of GMO studies in a peer-reviewed, high impact factor journal, Critical Review of Biotechnology (pdf). The authors collected and evaluated 1,783 research papers, reviews, relevant opinions, and reports published between 2002 and 2012, a comprehensive process that took over 12 months to complete. The review covered all aspects of GM crop safety, from how the crops interact with the environment to how they could potentially affect the humans and animals who consume them. Their conclusion, even in science-speak, could not be clearer:
The scientific research conducted so far has not detected any significant hazards directly connected with the use of GE crops.

The EU, which has shown some resistance to GMO crops, has spent over €300 million on GMO research over the last 20 years. Their 2010 report on GMO, which summarized the previous decade of research (pdf), concluded that:
It follows up previous publications on EU-funded research on GMO safety. Over the last 25 years, more than 500 independent research groups have been involved in such research.
According to the projects’ results, there is, as of today, no scientific evidence associating GMOs with higher risks for the environment or for food and feed safety than conventional plants and organisms.
Remember, scientific consensus is not based on debate or arguing. Yes, the lone voice pushing new ideas or fighting a dogma should be given a pulpit to share their evidence. And that’s the key point, evidence matters, dramatic beliefs do not. If someone is going to state that GMO’s are unsafe, then they need to bring evidence, published in real journals, that carry the same weight as the thousands of articles that say “GMO’s are safe.” Just like the climate change deniers, who claim there’s a scientific debate, but have never brought the quality and quantity of evidence of the climate change supporters, the anti-GMO crowd uses the same exact tactics–screaming and yelling about the dangers of GMOs using very bad science.
And right now, the scientific consensus regarding GMO’s is solid–they are safe.
