We really need to change our farm practices, ceasing to hose down our food in glyphosate and atrazine seems like common sense. If we only sprayed the weeds, like we used to before GMOs, it wouldn't be a problem. There are sustainable farming models that work quite well. Possibly a bigger existential threat than climate change is soil depletion and erosion. And it's all connected to air quality, water quality, obesity, chronic disease, cancer, autoimmune disorders, etc.
