Glyphosate has a half life of 3-4 days in the soil. It attacks a certain plant gene - unless you have that plant gene, you are not effected by glyphosate, in fact, you take in more harmful substances as a matter of course from other products such as food dye, cosmetics, frozen foods made/packaged in China, etc.

I don’t eat soil.
