Search the web, save the environment!
I have recently added Ecosia as a plugin to google chrome. It is a search engine where every time you search via the site, you contribute to a tree being planted. Ecosia, like most search engines uses adverts to develop an income, however Ecosia donates 80% of that income to a tree planting project in Brazil.
Ecosia graphics are fun and upbeat and the best bit is it keeps track of how many trees you have helped to plant. I have apparently planted 18 trees since i started using Ecosia only a month ago.
Im not sure of the actual contribution using Ecosia has, or whether 18 trees have actually been planted thanks to yours truly. Nevertheless, I always like to support positive initiatives especially when its helping to replenish trees which are so vital to human survival and the biosphere.
Below is a link to a video explaining what Ecosia does and how.
