... I actually believe we are smart enough to survive (not all of us) and will leave to go find other planets to infect.
Reckon we are, but part of me also reckons the 'smart' are often the least likeable, and the kind that caused the problem in the first place. 'Smart money' is buying fresh-water resources in the third world as discreetly and as quickly as it can. 'Smart money' is buying real estate in wastelands like N Canada, because that will be the new temperate zone. 'Smart money' will have the best seats on the space ships... the nice guys are too busy helping their neighbour to look after number one!
(Historically, the dispossessed are the ones who 'boldly go', driven by necessity. So the story of America, for example. But then when someone builds a space ship, it's unlikely the tickets will be in the reach of the dispossessed? maybe some will crowdsource the funds to build a Martian spaceship ... anyone thought of that?)
It stemmed from a question is man part of nature... To which I thought...naturally... But it appears we made up that word nature and we made it to mean that which is not us.
I think that's a relatively recent idea. It's a consumer notion, really, the way I see it.
I eventually came to the conclusion we are not only not nature....we are its worst enemy.
Nah. We might well be our own worst enemy. Nature doesn't even notice ...
Fact is the planet will also survive...after we make it uninhabitable for us and the thousands of other species we extinct in the process...the earth will survive, evolution will continue, and we'll hope it does better next time...
Well evolution is part of the problem. Or the notion that it progresses in a straight line, and that line is progressive towards some goal ... it ain't. It's random. If there's a goal, there's an architect.
And as for 'the blue planet', it's all a fluke. We're in the 'goldilocks' position, and organic life is the product of so many 'fluke' events that it's a strong scientific argument to suggest there isn't life elsewhere ... the odds are stacked against it, but then in an infinite space, who knows?
The point is, an infinite number of monkeys at typewriters can come up with the complete works of Shakespeare, but not necessarily. They might never. Same with the Cosmos. Theoretically it can replicate a similar set of conditions, given its infinity, but that doesn't mean it must, or it will. Certainly not on a timescale that's relevant to us. I would say the odds of earth meeting another species like our own, within the timeframe of our own species, is tantamount to a proof of God!
The cosmos isn't working towards life as it's goal, life is just something that happens as the product of some random events. The odds of such events being replicated elsewhere are limited, but then space is limitless, so who knows?
But the idea that life 'must exist out there' does rather rest on the idea that something wants life to exist, or our notion that we think that life is the best thing since sliced bread ... that evolution necessarily means life ... Does it? I don't think so.
If evolution was heading the way the Enlightenment thought it was, then we're also heading towards the best virus, the best cancer, the best bacteria, etc.
Remember we're only here because of previous 'extinction events' that killed everything and remade the environment. Our oxygen rich atmosphere is the result of one such 'fluke' event. We've had meteor strikes, ice ages ...
Professor Laycock, a guru I much admire, the proponent of the Gaia Hypothesis (not the romantic goddess nonsense), reckons nature will shrug off the human species, with about 80% extinction.
I wonder if evolution is not like a monkey at a typewriter, just banging away, and every now and then something makes sense? Life just keeps having a go, and every now and then something happens to survive long enough to impact the environment and alter the ecology. No guarantee that there's an evolution event round the corner that will undo everything so far ...
