One of the big things I (and many others, I'm sure) have neglected in "going green" is recycling. It is extremely easy and a huge step toward reducing waste. While the big goal is to reduce consumption in general, what you can't reduce you should recycle!
So I'm on a recycling adventure. In my town you can recycle metal (aluminum and tin cans), newspaper, and cardboard. There is no pickup, so I'll have to haul it myself. I saved a trash can from the landfill (i.e. found it in the dumpster) the other day to be a recycling bin for my tin cans, and for now I'll use two cloth bags to hold newspaper and cardboard (until the dumpster yields more trash cans). I don't want my tins to stink until I have enough to carry, so I'm washing them with my dishes.
I'm pretty excited about all this. I knew you could recycle aluminum here, but I hadn't thought about tin cans. So I'm taking one more step.
