Except, thanks to us, that’s not what would happen. We’d happily wipe out whatever began to fill that niche. If, that is, we haven’t already wiped out anything that might be able to fill the gap.
No, an insensate planet doesn’t care. But when somebody talks about destroying the earth, they’re usually talking about the life forms on it, not the planet, itself.
Not a big fan of the blue-green algae argument. Or of the “All I personally care about is humans” argument. Those are nothing less than arguments in favor of mutually assured destruction. It’s the sort of thing you’d expect to hear from those nutjob Christians who want to bring about the end of the world and from greedy politicians and business owners who want to exploit even more and poison even more so that they can make a little more money.
Can’t let a little catastrophic climate change get in the way of the bottom line, after all.
Probably not. History is replete with excamples of humans eliminating one animal and one por more animals just takes that niche over. Or plants. Or who knows. The ecosystem marches along.
That just doesn’t logically follow at all. It’s a total break in anything approaching reason or common sense. Being concerned about humans means NOT wanting them destroyed, which means, inevitably, finding ways to NOT alter the environment in ways that end up killing people.
