What is yoga doing here as an ‘action’ for mitigating climate change?  Well, one of the societal things that contributes to our excessive use of energy, and hence fossil fuels, is that we have become dependent upon all the ‘going’ and ‘doing’ for exercise, entertainment and enjoyment.  Yoga (and things like it) can serve all three functions for you.  They can provide the exercise you need to keep healthy, the entertainment when you listen to music while practicing, and the enjoyment through how much better you feel when doing it and afterwards.  Plus, yoga has the side-effect of producing wisdom and calm in those who learn and practice it.
