Happy Earth Day!
Here's one practical everyday way you can move toward the zen of zero: rethink the way you buy food. Skip the bagged salads and canned foods and buy fresh whenever possible. And in bulk. Many stores offer items package-free. Take your own reusable containers — cloth or net bags for produce, beans or flour, and glass jars for olive oil or honey — and, suddenly, you're using a lot less plastic.
