I'm not some vegan elitist dbag preaching about some hippie bullshit, I can go and Google a whole slew of scientific studies / articles that show the dangers to humans that synthetic nutrients pose. The world was doing just fine until we started trying (and failing) to replicate and manipulate it in a lab.
