  >all life known in the universe will be wiped out. Is that a problem for you? And why would it not come to existence again somewhere eventually? Its interesting to think about such stuff but it really should not have an impact on decisions we make today because it just not possible to affect a so distant future (thousands of years) in a meaning full way. Just imagine humans 2000 years ago what could they have possibly done that would have had a positive environmental effect today. And that's just 2000 years ago. If you apply this to mining the see floor. Do you seriously think that if we today decide that human should not do this that it wont be done in 2000 years? I think is far more likely it just pushed a little back in time an insignificant little, maybe one human life maybe even two who knows but in 4021 no one cares if it started in the year 2021 or 2121 that's for sure. Also if you want our species to become multi planetary then the only logical thing to do is to use all resources available achieve this as soon as possible. If we used up the resources or have way more humans and no spear resources no one is going to achieve it anymore.
