How it works? You search the web with Ecosia. Search ads generate income for Ecosia. Ecosia uses this income to plant trees. The Ecosia community plants a tree every 11 seconds, more than 6 million trees are planted so far. The goal is 1 billion trees by 2020. They publish donation receipts and business reports in every month and it appears they really do, what they're claiming to do. I'm not the biggest green person, i mean i love nature, who doesn't, but i don't think that i do enough to protect it and this seems like a good thing to do with no effort or investment from our part. The results what Ecosia gives you are relevant, it looks a lot like Google, so i guess it doesn't hurt much if we use their search engine sometimes instead of Google. Let's plant some trees!
