Thanks to reader Andy for sending along this tip on a really great project he's working on. It's not about a business that's doing something interesting with renewable energy, but it is definitely is innovative and fits today's theme.
Tree-Nation is an organization that aims to plant 8 million trees in Niger, Africa in the shape of a huge heart to combat deforestation and global warming. Visitors to Tree-Nation's site can buy trees for themselves or gift them to others for milestones such as weddings and new babies, or even to advertise a business.
Purchasers of a tree plant it on a virtual map and then a real tree will be planted in the same spot at the park in Niger. There are four different types of trees to choose from, including different forms of acacia, a palm tree, or the towering baobab.
The trees even have their own blogs and profiles so you can interact with the folks who bought the trees or the recipient of tree gift.
Since the project launched late last year, 325 trees have been planted - so they have a ways to go. But even if you don't want to buy a tree, the site is worth checking out just for the cool mapping technology.Tree-Nation is affiliated with the United Nations Environment Programme's Billion Tree campaign, whose mission is to plant a billion trees worldwide by the end of 2007 to fight deforestation and raise awareness of global warming.
