I just recently translated a Chinese study on the effect of glyphosate (Roundup is the trade name) on mice which found in males that it damaged their sperm, reduced the weight of their sexual organs and could potentially cause mutations in their reproductive cells. The obvious suggestion was that prolonged exposure could be dangerous to humans, though probably more so to people who are doing the spraying. Even so, the results of other studies have been inconsistent, so there's no definitive word on how toxic or damaging Roundup might actually be.
So what did people with allergies do before Roundup? Suffered, probably. Though they were also exposed to more bacteria than we are today in our obsession with being antiseptic, helping them to build up resistance and resulting in fewer allergies.
It's good to play in the dirt when you're growing up.
