> if labeling it a threshold in media intended for non-scientist audiences captures attention and calls readers to action, great!

There's not a lot of things that I could personally do, and that really bums me out. While my life choices already contributed to at least one person not polluting the planet a lot (as an example, I don't drive a car and I don't use gas for heating), I don't see much more I can do about it.

I know I get my electricity from a coal plant, and I can't really save on electricity more than I am now. Recycling is something I'm doing as thoroughly as I can, but it's a bitch in a city where there are only two locations where I can dispose a recyclable waste.

I can't really do much more, and I'm not even reducing the waste at all. I'm just living my life avoiding to pollute the earth even more.
