GMO basically emphasize the problem of losing crop diversity, in favor of single kind of it, that may have an advantage short term in economical terms for industries and consumers (lower price) but then it mean we eat standardized flavorless shit and we lose lots of local crops. Happened already before, will happen again. South italy for example was ruined by this during the thirties because fascism tried to enforce mass production, which in turn destroyed all the niche agriculture industries that would've been a much better choice in the long term economically.
Also mean that basically all farmers becomes dependent from multinationals even more for seeds and everything.
All this for what? More gain for corporations? Slightly lower prices for me? Yeah, i'd rather not thx.
BUT WE CAN SAVE WORLD HUNGER WITH GMOs! We can already produce enough food, it's just matter of policies. Even if we could, tomorrow, plant an infinite food seed, people would still starve because companies want to make profits. You know what could solve world hunger better? Not being so dependant on those corporations, promote agricultural diversity and locality to give power to local economies, and avoid being so keen on mass-producing shit that only push small farmers away from competition and concentrate economical power even more in few hands.
Health concerns are largely unfounded though. It's extremely hard to imagine that such things could actually do harm, even if i think it's likely that they'd be less good for your health because a lot of what does you good are the micronutrient that could disappear in such crops in favour of other proteins/ oils. All the things that do you good in artichokes are in the mg/ug range for example, and i could easily see some balance in cellular production being skewed in GMOs variants.
