So, what if we were faced with the same situation now? How much time would we need? Where would we go? How would we get there? How many people would we realistically be able to get off the planet? Lots of questions, very few answers. But when in doubt, ask someone who knows something about science.  Well this week Peter and Richard are joined by a real "science guy"...Bill Nye "the Science Guy" in fact. One of the true trail blazers in science communication joins "What If Discussed" to help us find an answer to "What If we had to evacuate Earth?".
