This article seems to suggest GMO crops reduce pesticide use. Maybe we need to collect the data for both GMO crops and non GMO crops on pesticide use. But who should we trust to collect that data? https://allianceforscience.cornell.edu/blog/2020/07/new-study-gmo-crops-reduce-pesticide-use-greenhouse-gas-emissions/ https://allianceforscience.cornell.edu/blog/2020/07/new-stud...

Your article is about pesticide use. But I am talking about the increase in herbicide use. Monsanto’s “roundup ready” line of GMO products is intended to be blanketed with glyphosate (aka RoundUp), a powerful herbicide. According to the following study, glyphosate use increased 15 fold since the introduction of “Roundup Ready” products. https://enveurope.springeropen.com/articles/10.1186/s12302-016-0070-0 https://enveurope.springeropen.com/articles/10.1186/s12302-0...

  Funny thing is, once people started blanketing with roundup, it didn't take long for roundup-resistant weeds to develop. > Growing reliance on the broad-spectrum herbicide glyphosate has triggered the spread of tolerant and resistant weeds in the U.S. and globally [5–10]. To combat weeds less sensitive to glyphosate, farmers typically increase glyphosate application rates and spray more often [11–13]. In addition, next-generation herbicide-tolerant crops are, or will soon be on the market genetically engineered to withstand the application of additional herbicides (up to over a dozen), including herbicides posing greater ecological, crop damage, and human health risks (e.g., 2,4-D and dicamba) [6].

  Roundup is used at tiny quantities. Yes 15 times as much is used, but that is still much less than a liter per hectare. And roundup strongly binds to dirt where nothing can get it until it degrades in about half a year. It degrades into common elements in the soil so it isn't making any difference.

    According to this link, our original belief that it’s use is largely benign needs further study: https://pubmed.ncbi.nlm.nih.gov/29117584/ https://pubmed.ncbi.nlm.nih.gov/29117584/

      Anyone can publish anything. Such as calling out the WHO even though they ignored most of the evidence. Then speculation about antibiotic resistance even though bacteria don't use the pathways glyphosphate targets.
