Jen Gale's Tip:
A super easy switch that you can do from the sofa is to switch your search engine to Ecosia (www.ecosia.org/) - the search engine that plants trees!
You can add it as a browser extension to your lap/desk-top or download the app for your phone (if you do this, just drag it to the place where your normal browser sits on your phone and then your thumb will go there automatically!)
Ecosia use their ad revenue to plant trees and according to their website, each search with them removes 1kg of CO2 from the atmosphere, meaning that if Ecosia was as big as Google, it could remove 15% of global CO2 emissions!
