This video explains how glyphosate, the main chemical in the weed killer RoundUp, causes cancer in a person whenever the product is being used. Glyphosate is so strong that it can break through protective clothing and that it can break through skin. If you would like to see if glyphosate will cause cancer for you, then you can buy RoundUp at your local hardware store anywhere in the world.
The video is sort of long at 13 minutes and 35 seconds, but the clip gives you a step-by-step process on how glyphosate is able to break through protective gear and attach itself to skin membranes.
Very dangerous chemical for sure.
I hope that you don’t use that stuff in your garden.
