Is it the blind and purposeless nature that should not care anything about survival of whatever, as to lead to stability of surviving species, in the time span they do survive in?
Almost.
The environment is what it is. As you say, it really doesn't care about anything.
Those species that survive, survive. Nothing related to care or purpose.
If the conditions change, the surviving critters may well become the losers.
That's how it works.
Anyone so limited that they can only spell a word one way is severely handicapped!
