Dennis McKenna | What the Plants Are Telling Us

Dennis McKenna is a world-renowned ethnobotanist and public speaker and founder of the new organization the McKenna Academy for Natural Philosophy. In his talk at AYA2019, McKenna explored the notion of plant intelligence, describing how plants communicate through chemical messenger molecules, and how hyperconnected networks between organisms support life on earth.

McKenna's key message is clear: Mother Earth, through her plant messengers, is sending global humanity a wake up call. To wake up to our relationship with Nature. To wake up to our responsibility to care for the plant. And to take action.

Following McKenna’s presentation, moderator Sir Gillhean Prance shares his perspective on what the plants are telling us, providing examples from his work as an ethnobotanist. He says, “All over the world I go, the plants are telling us that there’s something wrong with the climate.”

A global shift in consciousness

He is the brother of well-known psychedelics proponent Terence McKenna and is a founding board member and the director of ethnopharmacology at the Heffter Research Institute, a non-profit organisation concerned with the investigation of the potential therapeutic uses of psychedelic medicines.

Dennis & Terence McKenna

Dennis McKenna and his late brother Terence are known as pioneers of the psychedelic movement. The American ethnopharmacologist, author and psychedelic expert, Dennis has been a leader in psychedelic discovery and the use of plant medicines, including psilocybin, DMT, and ayahuasca for over four decades.

The McKenna Academy of Natural Philosophy

Earlier this year Dennis founded The McKenna Academy of Natural Philosophy, dedicated to advancing a symbiotic and co-evolutionary partnership, with the entire planetary community of sentient species.

I was super excited to have Dennis back on the show for a second time. We talked about everything from climate change to the Reconnect movie we made together where Dennis and I travelled down to Soltara in Costa Rica to partake in three ayahuasca ceremonies.
