As global warming continues and space technology improves, there is more and more talk about the growing possibility of a sci-fi future in which humans become a multiplanetary species. Specifically, that we could live on Mars. Biologist

Zach Weinersmith have spent the last four years researching what this would look like if we did this anytime soon. In their new book
A City On Mars, they get into all sorts of questions: How would we have babies in space? How would we have enough food? They join host
Regina G. Barber and explain why it might be best to stay on Earth.
