Wouldn't want to read this thread hungover
To be fair life popping up then dying then being replaced is a process that started when the Earth was formed and life appeared.
This process will continue and repeat until the Sun expands across the orbit of the Earth, leaving it a smoking molten shell where no life is possible.
Life is chaos and action. Enjoy it while it lasts
Mankind gets a bad rap, but cosmic events and extinctions are just as much of the process. I have no doubts that a few hundred million years after we've been gone, then any new intelligent race would likely take the then resources of the planet when they too have the chance.
I've said for years now that the only hope mankind has of surviving is to move to more than one external site - wether that's at lagrange points on tamed asteroids, in craters on the moon, in the asteroid belt or on ther planets or in solar orbiting stations - until we do that we've had our chips.
The biggest advantage is that you can start moving heaving industry, power generation and pollution off world.
Can we do it before we're stuffed?
I'm an optomist, so I think we can. Humanity isn't all bad and in many scenarios, we can tut and frown now, but putting yourself in their ideas and situation years ago, many of the realisations that seem obvious today weren't even considered then. We're basically big fat intelligent fish living in a cloudy fishtank that we can't clean and the filter is fucked. An enclosed biosphere means that there is nowhere for the shit to go and when some of that shits effects last millions of years then you have an issues - especially if you keep creating said shit..
