Ecosia is a new search engine that donates at least 80% of it's profits to the World Wildlife Fund for Nature (WWF). The engine is partnered with Yahoo and Bing to provide search engine results as well as sponsored links.
On average users can save about two square meters of rainforests with every search they conduct. All the Ecosia servers are also run on green electricity, which have no CO2 emissions.
So far they have saved 35,617,462 yd˛.
I've always been a fan of Google but I think I will use Ecosia for now on.
