Almost 2 years ago, I began a compulsory sustainability course as part of my degree. In modern times, this isn’t such a strange thing to do; it’s important that we tackle the climate problem head-on and you can’t do that if you don’t understand it. It’s easy to think “what’s there to learn about?”, after all, we all know that CO2 and Methane emissions are causing the earth to warm and the climate to change.
