This year, the Church of England has encouraged Christians to undergo a “carbon fast” for Lent, the 40 days prior to Easter. What is a “carbon fast”? It’s when you give up things that increase your CO2 footprint (or release more CO2 into the environment). The rapid increase of this greenhouse gas in the atmosphere is one of the causes of global warming. You can find out more about the carbon fast by visiting Tearfund. Participants are encouraged to do things like take a shower instead of a bath, turn the thermostat down by one degree (or up, if it’s summer where you are!), or, my personal favorite, remove one light bulb from your house as a visual reminder that you are trying to live with less during this Lenten season.
