Ecosia is a search engine that saves about 2 square metres of rainforest for every search you make!
They earn money from clicks on the sponsored links, which are displayed next to the generic search results. Each click on one of these sponsored links generates a few cents of revenue. About two percent of the search requests end up with a click on a sponsored link.
Ecosia donates at least 80% of this money to a rainforest protection project run by the WWF in Juruena National Park in Brazil.
So far, according to their website, they have over 48,000 active users who have helped to protect 21,006,450m² of rainforest.
You can help save the rainforest for free by using Ecosia for all your internet searches - and by spreading the word about Ecosia. The more people using it the more money they can make.
