The answer is yes, if your environmental sustainability projects or daily actions increase health and wellbeing of all of nature including yourself. If that is not the case, then maybe its time to inject a bit more heart into what you are doing and how you are being.
Think about any interaction with nature that left a positive impression on you, it may have been simply hearing the birds this morning. What would you need to do to create more of that -more hearing, more birds. Is there a step that you can take today to make that happen?
