The author concludes that genetically engineered plants will be harmful. His reasoning is that the experts now promoting genetically engineered plants were previously mistaken about non-native plants, which have turned out to be harmful.
This is the cookie-cutter ad hominem flaw. The author attacks an argument by trying to discredit its proponents. But this doesn’t tell us anything about the merits of the argument itself. Even if the experts were wrong about a different subject previously, perhaps genetically engineered plants are actually harmless.
