[QUOTE="Mustrum_Ridcully, post: 7555343, member: 710"] The revealing question to ask might be: If we had time to prepare, which would be harder: Building a colony on another world (Mars probably), or creating habitats to survive in on Earth? What if we had to prepare for all of these possible catastrophes at once? (Without preparation, one could claim the Mars colony is better - except building that colony itself requires preperation - and time we could spend on building a safe habitat on Earth.) Interestingly, the "Gamma Ray Burst" is a scenario where we wouldn't be safe on Mars or probably any planet we can reach in the forseeable future. But AFAIK, there are no known stars near enough that seem capable of creating such a burst and be a danger to us. (How boring...) Another thing is: Make no mistake, any of these events would be brutal to humans. Climate Change for example we can probably survive, but how many people would die due to crop failures, and how many more would die because of the resulting wars over resources? None of this is nice, it would still be better to avoid any we can avoid. [/QUOTE]
