Pesticides are, generally, safe to humans. Herbicides are, generally, not at all safe to humans. Roundup is probably the most safe outside of per-emergents like corn husks or whatever, but it's not a free ride either.
> Pesticides are substances that are used to control pests. They include herbicides, insecticides, nematicides, fungicides, and many others (see table). The most common of these are herbicides, which account for approximately 50% of all pesticide use globally.[0]

You're trying to be pedantic, but you're actually wrong. If you think about it, from the perspective of anyone trying to raise crops, weeds are pests. (They are pests to lots of non-farmers, too.)
Similarly...
> A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes.
> Plants may be considered pests, for example, if they are invasive species or weeds.
Like if I drank a 1/4 shot of Vodka every morning I wouldn't notice it at all, but I imagine it would have some impacts on my health over the long run.
Not to mention we might have 30+ chemicals/medications/additives/whatever all being consumed constantly at "safe levels" with no research into how they interact or accumulate.

It's a chasm-leap to say that pesticides are generally safe to humans.
Out of curiosity, why?
