I STILL see people do that! Especially in Las Vegas. :P Yuck. I still see people throwing their (still burning) cigarette butts out, and while it makes me cringe, I admit I used to do the same thing in my early 20s. (blush) One time, I even had some guy pull up next to me, roll down his window, and scream some obscenities to me for doing it. Back then, I was outraged he yelled at me, but now, I SO get it. :)
How about using styrofoam containers for everything?
Wow - once every two weeks is great! I can definitely see the draw to disposables. After all, they were designed to make life easier. The harm just outweighs the benefits.
I wonder, did we not see the potential downside long ago when we were coming up with ideas like disposable plates and cups?
