Action is the antidote to anxiety and despair. Climate change feels like an overwhelming inevitability, but if we can find any way to contribute to healing our planet, we can gain a small degree of comfort and feel engaged rather than passive. One ‘theory’ is that we can change our habits if we stick with it for three weeks. So here’s the challenge: starting with the easiest habits to change, food and waste food. Of course many of you will already be aware of these habits but there are many others who haven’t got around to thinking about climate change, especially whilst we also deal with covid, so this might be a nudge in the right direction.
