Maybe...

Maybe homelessness is useful in combating global warming. I was walking home today and watched a few homeless people picking cans out of the trash. They always come down the street on garbage day to collect the cans and bottles that they can refund as well. (I'm way to lazy to take those cans back to the store to get the deposit back. I'll just throw them in the recycle bin.) I bet most people are like me and are too lazy to take them back to the store, or they don't have enough room to store empty cans.

So maybe homeless people are useful in terms of reducing our carbon footprint because they are highly motivated to do something about it.

How do we get everyone to be highly motivated to reduce the causes of global warming?
