Kurzgesagt Podcast: Science Revealed

What if humanity could one day transform Mars into a world capable of supporting life? Terraforming Mars is one of the most ambitious ideas in science—but it could take centuries, enormous resources, and technologies we don’t yet possess.At the same time, Earth already provides everything we need to survive. So should our priority be turning Mars into a second home, or solving the environmental challenges we face here first?In this episode, we explore the science and possibilities of terraforming Mars, the enormous challenges involved, and the ethical question at the heart of it all: should humanity focus on creating a new home—or take better care of the one we already have?
