I came across a new (to me) search engine today and if what they saying is true, the searches we make go towards planting trees - which has to be a good thing.
Plant trees while you search the web
We use the profit we make from your searches to plant trees where they are needed most. Get the free browser extension and plant trees with every search.
Have a look and if you like the idea why not switch from Google to Escosia.

There is also a little tree counter at the top, my guess is that it counts up the trees you have contributed to by your searches. I searched TREES as my first search.
