I recently gave a TEDx talk 'From Egoism to Egoism: Psychedelics and Nature Connection' at a TEDxOxford 2019 event on the capacity of psychedelics to increase human-nature connection, and the implications this has for human wellbeing, as well as the wellbeing of the biosphere at large (human-nature connection is strongly correlated with wellbeing, and also is a strong predictor of pro-environmental attitudes and behaviour). This isn't one of my best talks...the day of the TEDx was definitely one of the most stressful of my life thus far, the cortisol was really flowing! Hopefully I succeeded in getting the message I was trying to across. I thought it may be of interest to some Nexians.
