Like Trixie, I was so pleased that I could help the world be a better place but as a previous DuckDuckGo user the benefits of it, far outweigh the trees I planted.
Due to concerns about page filtering, malware, and country specific information when searching means I am going back to DDG. I will just give a bit more to tree charities now.

Actually, I kinda like the fact that with my using of the search engine I contribute for a better world. However, it seems to be aimed for people who use google. As a main Duckduckgo user, used to instant correct search result with an easy access to country specific research, I really can't recommend it.
