Is that based on research you've done, or are you just going with your gut?
This[0] article explains how "Roundup-ready corn and soybeans"(roundup is an herbicide) has caused the near disappearance of milkweed and because of that the near disappearance of Monarch Butterflies which need the milkweed to survive. What does "roundup ready" mean? It means the corn and soybeans can tolerate the herbicide, so the fields are coated with it indiscriminately. I'd wager that acres of corn and soybeans planted exceeds acres of papaya by a fair bit.
This[1] well-sourced[2] article describes "Herbicide and Insecticide Use on GMO Crops" as "Skyrocketing."
This[3] article describes how corn crops that are gm'd to be resistant to pests have actually become susceptible to pests because "nature will find a way." This has resulted in even more use and need of pesticides for these crops, a vicious cycle.
By the way the crops that are modified to "not need pesticides," still actually need and use pesticides. The pesticides are just incorporated at the gene level, instead of after they've already been planted. For example, the use of systemic insecticides, which coat GMO corn and soy seeds and are incorporated and expressed inside the entire plant, has skyrocketed in the last ten years. This includes use of neonicotinoids (neonics) which are extremely powerful neurotoxins that contaminate our food and water and destroy non-target pollinators and wildlife such as bees, butterflies and birds. In fact, two neonics in widespread use in the U.S. are currently banned in the EU because of their suspected link to Colony Collapse Disorder in bees.[1][4]
And the roundup ready type gm is one of the main things I've heard touted about gm over the years, I'm not sure where you're getting your information.
Over 99% of GMO acreage is engineered by chemical companies to tolerate heavy herbicide (glyphosate) use and/or produce insecticide (Bt) in every cell of every plant over the entire growing season. The result is massive selection pressure that has rapidly created pest resistance--the opposite of integrated pest management where judicious use of chemical controls is applied only as necessary. Predictably, just like overuse of antibiotics in confined factory farms has created resistant "supergerms" leading to animals being overdosed with ever more powerful antibiotics, we now have huge swaths of the country infested with "superweeds" and "superbugs" resistant to glyphosate and Bt, meaning more volume of more toxic pesticides are being applied.[1]
