ELI5: How come the EPA says glyphosate is harmless yet at the same time a $10 billion lawsuit on glyphosate causing cancer has been reached?

As is the case with nearly every poison, it isn't the substance - it is the dose.

Nearly everything in the world is bad for you in the right amounts and there are a million and one things that will give you cancer if consumed in the right amounts.  The question is whether or not you are consuming amounts high enough to be problematic.

The EPA sets minimum levels for a host of chemicals because they argue that amounts lower than that are not harmful (they are wrong from time to time, but that is the logic).  Since it is neary impossible to get levels to zero, the goal is to keep them low enough as to not be harmful.
