People often ask what I kept from the No Impact year, and there's a lot I still try to do. I bike most places, I buy only second-hand, we don't have air conditioners.
But there are certain things that are lines in the sand for me and bottled water is one. I just can't bring myself to use or buy it. Pretty much ever (info on bottled water here, by the way).
What about you? Do you have any eco-living lines in the sand?
And I'm curious, too: I know why having such lines in the sand is important to me. Why is it important to you?
