I don't say this as a personal attack at all. I know that people who care about the environment really think there is sustainability problem. And I know they think that those who don't are evil. But I guarantee you, there is no sustainability problem. It is all lies. I can surely convince you if I have enough time, but I don't. So let's not fight about this please. No bad feelings. I care about the environment, but I am not worried.
Are you sure this is not wishful thinking?
Because you know/fear/block that if in our future we hit scarcity in resources we are going be regulated like never before.
I fear that we will even lose liberties that never knew we had, like liberty to breath, mate, move, sleep, not die a random death.
Think about the way of life of astronaut, it is the future, and it wont matter if you are on the planet or not.
