The planet itself is a global ecosystem and we're destroying by damaging ecosystems. Is it natural selection for us to cut down trees that convert CO2 into O2? Human intelligence and adaptation is a design flaw, a good one but one that is ultimately damning. We have the ability to evolve past the basic needs of survival and we've gone into what no other species has done before and that it we are fulfilling wants.
We're destroying the global ecosystem to fulfil those wants this isn't natural selection. Humans are essentially a pest like a plague of locusts we have nothing to keep our numbers in check. We need to stop being a strain on the environment or we're going to destroy the planet or nature is going to evolve a super species that can fire lasers out of every orifice to kill us.
If we destroy our environment, we will be faced with the same fate as every other species that destroys it's environment.
We will run out of resources and die out.
It is precisely natural selection. Ability of an organism to gain resources essential to live and breed is required for it's survival.
If it destroys it's environment beyond the point of recovery, that organism (and if it happens on the large scale, entire species) will just be removed from gene pool.
A lot of people think, that for some reason principles of evolution doesn't apply to humans (because we have intelligence, technology or whatever). They're wrong.
All replicators are subjects to natural selection. Truth is, in our current evolution, sexual selection is becoming a more important factor than natural selection (because we are not so much competing for resources anymore, which we have in excess when it comes to food and water; and more for an attractive partner), but that doesn't matter all that much.
As to damaging ecosystems, many organisms damage their ecosystems, sometimes beyond repair. The most common are bacteria, viruses (not really an organism, but a replicator nonetheless), some fungi and larger parasites, who can often kill it's host - and die with it. But other organisms do it as well.
Similarly, if we are not careful. we might destroy our ecosystem and die - but that would most likely require a catastrophy (like a worldwide nuclear war) because of how widespread we are as a species, and how quickly we can adapt.
I would say it is more likely that we will be wiped out by microorganisms, because our defenses against them are horribly inadequate, compared to our defenses and adaptations against larger organisms.
Still no. And you might still want to actually read up the definition. After all it's useless trying to discuss a point when one side evidently has little understanding of what the point actually is
Natural selection is a process, in which organisms that are better adapted to the environment tend to survive and produce more offspring.
That's it.
Apparently lions are not so well adapted to compete with humans. If it was the other way round, they wouldn't be on a brink of being endangered.
