Here's the perfect example of how social networking via the internet can bring change. Tree-Nation is a project aiming to get 8 million trees planted in the shape of a heart in the Sahara - yes you heard that right. This sounds like a colossal process, but is inherently feasible… via the web of course. You can join and buy a tree for as little as 10 Euros. By planting your tree, you can help combat desertification and regenerate the productivity of the land. This in turn will have a major impact on the livelihoods of the poor in the region.

"When we plant trees, we plant the seeds of peace and the seeds of hope"
Prof Wangari Maathai.
