Ecosia.org - the search engine that plants trees
Ecosia uses the ad revenue from your searches to plant trees where they are needed the most. By searching with Ecosia, you’re not only reforesting our planet, but you’re also empowering the communities around our planting projects to build a better future for themselves.
Not the best search engine for porn, but I use it for some time now and for "normal" searches it fits my needs pretty well. Maybe someone give it a try.
