    Wanna say that I really like the content this channel produces. It helps me feel just that much better about all of these crazy "what-if?" scenarios that we thought about when clicking on the video. They're so very well put together (quite unlike myself) and they're so smoothly animated! It feels like I'm watching a school cartoon but without being talked down to in the narration. This is great!

    So there's no real chance of people deliberately preparing to ensure the species survives a GRB, but there is a pretty decent chance of people colonizing the bottom of the ocean, simply because there's ore and potential food-growing space down there(also because the idea of subaquatic cities tickles the imagination). Would a self-sufficient set of aquatic habitats survive a GRB event? how deep would they have to be?
