I didn’t discuss insect repellents. I discussed roundup, the herbicide. GMO crops are engineered so they can be sprayed with roundup and not die. It’s an easy (but as it turns out not so cheap) way to keep weeds down in your field.
Unfortunately the crop you’re growing ends up saturated with glyphosphate. aka Roundup.
So what we are dealing with is a food product saturated with a poison chemical. Is this the issue?
