Greta is the woman (and she's only like...16, I think?).
The worst part of the whole thing was the smug asshole Garret Graves asking, "If you were sailing across the ocean and you were picking up trash along the way, and for every piece of trash you picked up there's a boat right next to you dumping out five pieces, how would that make you feel?"
It's such a dumb, and unneeded question. How would you feel? I don't care how someone would "feel". Basically he was saying, "If everyone else is doing it, why bother trying to fix it".
