We have a week to go before Earth Day arrives on April 22, but that doesn't mean you can't get your green on a little early. In fact, there's a concerted effort to claim the whole of April as Earth Month. And why not? What's one month to take stock of how we treat the planet we call home?

Marking the occasion, NASA released an inspiring video, "NASA Science Eyes," recently to shine a spotlight on sustainability. The video shows how its "fleet of science satellites and research aircraft are at work around the world 24/7 helping scientists discover just how our living planet really works." The video, shot from the International Space Station, is a glorious and impressive view that could move anyone, from eco-nerd to science geek and more. Sure, we may have see similar kinds of imagery in scifi shows and movies, but there's something amazing about taking all this in, knowing it didn't come from CGI masters in Hollywood.

I challenge you to look at this and not feel moved to protect this magnificent planet. Go ahead, I dare you.

  • Turn off the lights when you leave the room, and use daylight instead of lamps whenever you can.
  • Power off your computer at night and shut down the power strip.
  • Unplug unused chargers, appliances and devices.
  • Contact your electricity utility provider and see if there's a green power option.
  • If you still get some paper bills in the mail, see if you can get online billing for those instead.
  • Opt out of pre-screened credit card offers online here
  • Watch (or rewatch) the Web classic "The Story of Stuff," especially with any kids in your household.
  • Do an audit of your old backup batteries, devices, computer monitors, printer cartridges and other legacy tech items. Repurpose/gift them to anyone who can still use them, and arrange for appropriate disposal of the rest. (Many manufacturers and retailers, like Apple and Best Buy, will take your old gadgets and dispose of them properly.)
  • If your laptop has a removable battery, take it out when you're home and run it off AC current alone. Oddly enough, even if your battery's full, it still draws energy from the plug. (This can even help maintain long-term battery integrity.)
