Earth Day 2011: Top 10 Green Properties Worldwide
In honor of Earth Day, we took a look at the top properties in the Green category worldwide. The annual Earth Hour (March 26) encouraged people to 'go beyond the hour', sending a record 60.4 million people to visit a Green site in March (up 5 percent versus year ago).
Planet Green Sites ranked #1 overall with nearly 4.5 million visitors, followed by Care2.com with 3.0 million and Nature.com with 2.1 million.
