Help Pick the Next Double Impact Challenge!

So far TreeHugger readers have picked 3 new challenges for the Double Impact platform: using dishtowels or cloth napkins instead of paper towels, switching to biodegradable plates and cutlery instead of styrofoam or plastic and closing the curtains to reduce a/c usage. What will you pick this week?
If you haven't joined Double Impact yet, it is a new platform that allows users to get credit for their green actions which then are turned into real world benefits for the charities of the user's choice. And since the platform is connected to Facebook, you can challenge your friends to see who can take on the most green challenges. It's a fun way to live green and help charities!
