30 Aug TED Talks – Dave Brain: What Planet Needs To Sustain Life
Venus is too hot, Mars is too cold, and Earth is just right,” says planetary scientist Dave Brain. He explores the fascinating science behind what it takes for a planet to host life — and why humanity may just be in the right place at the right time when it comes to the timeline of life-sustaining planets. Life is a gift. That’s why they call it the present. We are so fortunate to be alive given the improbability of life on so many other planets. Life is so precarious and fragile but we should make the most of it and live it to our full potential.
