eBay and Hearst, the magazine publisher, have teamed up to create a the 30 Days of Green Challenge to coincide with Earth Day 2010.

The Challenge asks participants to consider a variety of ways to act in ways that are friendlier to the environment. The associated web site offers tips and advice as well an opportunity to win $10,000 and a host of other prizes throughout the campaign.

Disclosure: I am a presenter for the eBay: On Location series and witnessed first hand some of eBay’s commitment to environmentally friendly practices first hand.
