where we re-imagine ecological restoration, promising a brighter future for human livelihoods and health as well as a just transition in a warming world.

Mar 9, 2020

Natural light from the sun is so vital to the health of every living thing. My guest on this episode is Dr. Travis Longcore. He is going to “illuminate” this topic of the ecology of light, especially focusing on impacts of artificial light at night. Light pollution doesn’t just affect our ecosystems. The loss of darkness is linked to increased energy consumption and a disrupted connection with the night sky. There are important consequences for human health too.
