Glyphosate wasn't developed for agricultural use until 1970. We're told by glyphosate propagandists that "80% of food crops" require glyphosate to produce.
How, then, did people eat before 1970?
I have a huge collection of newspapers from the 1950s and 1960s. Amazingly, they are all filled with ads for groceries, and the groceries were dirt cheap, even accounting for dollar devaluation.
Thus even with glyphosate today, food is presently way more expensive than it was before the rise of glyphosate.
Glyphosate propagandists want you to believe there's no food without glyphosate in the same way that vaccine propagandists want you to believe there's no immune system without vaccines.
