hmmm... ...let's see...
Internal combustion engine propelled vehicle - which I drive a lot - lawn mower & "weed-whacker" - those are all reputedly equivalent to death machines...
I eat my share of meat, and as we all know, livestock is worse for the world than a full-scale nuclear war...
I refuse to recycle anything, because it's too inconvenient... (plus it's part of my wee contribution to my own little "Extinction Agenda"...



)
I refuse to dispose of anything that's supposed to require a "special procedure" (eg, fluorescent bulbs, rechargeable batteries, &tc.) in any other way than just throwing them in the trash...
Speaking of vehicles, I have a habit of throwing empty beverage containers out the window of mine wherever I happen to be when I'm driving. (not to mention any other disposable thing which happens to be cluttering up the car for whatever reason)...
I'm sure there's more which are merely aspects of "modern life" that I'm neglecting to recall. And of course these are piddling little drops in the bucket in the scheme of things. Multiply this by umpty-bazillion bozos like me, though, and there you have it !
