This talk examines the top causes of premature extinction on Earth – climate change, biodiversity loss, ecosystems collapse, chemical pollution and more, and explains how a vegan lifestyle in conjunction with ecosystems restoration mitigates all of these causes. It advances the hypothesis that an ecosystems role for human beings as compassionate "Climate Healers" or as the "Thermostat Species" is in harmony with scientific facts as well as with the foundational myths of major religions. With strong scientific evidence, it shows why we need to transition to a largely Vegan World by 2026 to fulfill this ecosystems role, seven short years from now, or risk our own extinction.
