The Top Three Reasons for Humans in Space
An anonymous reader writes "Why humans in space? The Space Review has the top three reasons: 3. To work. 2. To live. 1. To survive. 'To work' means doing stuff in space: research, explore, visit, etc. 'To live' means to have humans/life beyond Earth in colonies/settlements. 'To survive' means that putting humans/life beyond Earth is a very Good Thing in case a very Bad Thing happens to humans/life on Earth."
#1 To Survive would only be a "Very Good Thing" if humans weren't the most incredibly sucky species on the planet. If exploring space will ensure human survival then that's a strong argument for not doing it.
You never really know how close to the edge you can go until you fall off.
