I have an oak tree in my yard that has produced so many acorns that after I raked up a giant pile, I decided to put them into their own can to see how much the tree would produce this year. I have already filled a 45 gallon can and more fall everyday.

I recycle my cans and bottles because the stores charge me 5 cents for each one and I want my money back. Otherwise I wouldn't do it.
I drive a fuel efficient car because gas is expensive. If I ever win the lottery, I'll drive a hummer.

If you really want to change the world ban the use of Dihydrogen Monoxide. It's the number one green house gas in the atmosphere. Green's go first, stop using Dihydrogen Monoxide, be an example for the rest of us.
