"What I do really doesn't have an impact on the environment. It's just a drop in the bucket."
I hear that a lot. But guess what -- each drop in the bucket combines with the other drops in the bucket and before you know it, the bucket's full! That's how it works. You carry your own coffee mug and skip the styrofoam, drip. You take your reusable cloth bags into the grocery store and bypass the paper or plastic question, drip. You decide to carpool one or two days a week, drip. You switch to cold water wash cycles, drip.
