This is a two-part answer. First, the big difference about GMOs is that "farmers must purchase fresh seeds as retailers sell them only as hybrid cultivars, which prevents growers from replanting them the following year." [3] You can imagine that this makes a huge difference in how farmers need to operate. Farmers do not store seed anymore like they used to but need to buy new seed ever year. If world market prices of their commodities drop they will not even be able to afford new seed & pesticides for the next crop, especially since prices for GMO seeds and brand-specific pesticides are a multiple of non-GMO seeds. With non-GMOs, farmers retain the possibility and the legal right to the re-seed next year. That is why this cycle is more vicious, especially for low-income countries where credits and loan are hard to come by. > You haven't mentioned any evidence which would inculpate Monsanto. Secondly, I explicitly linked an article titled "Death and Extinction of the Bees. The Role of Monsanto?" which is one of many others like the Guardian, citing University of Texas research [0], the German Office for Environmental Protection [1] highlighting the negative effect of RoundUp/Glpyhosat. All of these detail the negative impact of Monsanto's product on biodiversity in general and bees more specifically. So the evidence is not only about the negative impact of Monsanto's main product RoundUp on bee population but also Monsanto's documented efforts to prevent effective regulation and scientific discussion. For instance, the so-called 'Monsanto papers' "reveal Monsanto-sponsored ghostwriting of articles published in toxicology journals and the lay media, interference in the peer review process, behind-the-scenes influence on retraction and the creation of a so-called academic website as a front for the defense of Monsanto products."[5] Monsanto doesn't really help here and became the first company that has been "banned from entering the European parliament after the multinational refused to attend a parliamentary hearing into allegations of regulatory interference" [4].
