If every household in the United State replaced one regular lightbulb with one of those new compact fluorescent bulbs, the pollution reduction would be equivalent to removing one million cars from the road.

Don’t like the color of light? Use these bulbs for closets, laundry rooms and other places where it won’t irk you as much.

Start rolling those Rs: Reduce, reuse, and recycle-and in that order. Let’s face it, we’re mired deep in ecological debt because we’re consuming more resources than nature can replenish.

Separating recyclables from your regular trash, which barely takes any effort, is a no-brainer, of course; recycling aluminum, for instance, takes as little as 5 percent of the energy we’d need to manufacture virgin aluminum.

Choose furniture made from eco-friendly sources such as sustainably managed forests, bamboo, and reclaimed wood. Buying vintage wherever possible, rather than adding something new into the waste stream, is always in style. Also, look for furniture that is durable and likely long-lived-you’ll save money on replacements in the future and prevent more wasted materials from winding up in the landfill. And, if for some reason, that dresser or dining table no longer suits your needs, something in fine shape will always have takers via Craig’s List, eBay, or Freecycle.
