Since GMOs are primarily designed to be resistant to herbicides or insect pests, they are not engineered to boost yield. Thus, the claim that GMOs do not increase yield as an objection to GM applications that do not even attempt to boost yield is deceptive.
Since the amount of land that GMOs are grown on are increasing, you cannot naively claim that amount of active ingredient is increasing. When looking at it per area unit, insecticides are decreasing and glyphosate replaces more harmful pesticides. Follow the references in the original post.
Using “GMOs are banned” as an argument against GMOs is no more valid than using “homosexuality is banned in many countries” as an argument against basic human rights.
