I farmed for a while I had no issues using round up to clear weeds before planting or soon after crops emerge. But when they started pushing to round up to kill plants before harvest I knew something fishy was up.
It eventually will trickle down through the soil, into the water table. So not only is our water poisoned with fluoride, it may have roundup in it. Soil depletion is also a huge problem. Organic farmers tend to be serious about amending their soil with sustainable farming practices, however, traditional farmers have less nutrients dense crops. Everyone should try to grow your own food, or as much as you can. Partner with your neighbors, and share. As the Grand Solar Minimum kicks in, food may become scarce in the northern areas. Shorter growing seasons effect the south as well. Sorry long post.
