“The rodents are given oral doses of glyphosate for up to 89% of their life spans...”
If you want to drink Roundup for 89% of your lifespan, that is your choice.
The issue that’s of concern to meis that Monsanto also has genetically engineered crops like corn and wheat to be resistant to it, so it can be sprayed over entire crop. So you won’t know if the food you eat has residue. Also humans live a lot longer than mice. 89% of a mouse’s life isn’t very long for a human.
I’m not saying I buy all what the alarmists are selling, but some caution is in order if it’s being used widely on our food.
