If Life is Meaningless Anyway, then What's Wrong with Religion?

Emphasis mine. If they went extinct other consumers would fill the void. Try again, Huggy.

Uh no, that's not what it's saying.

It's flexible because it has a wide variety of prey it can consume...

Blah.

Designating an organism or species as "necessary" is very tricky.

Are humans necessary? Well, without us, a lot of livestock animals and crops that have been cultivated by humans for centuries would no longer be able to survive and propagate. Thus, we are necessary for their survival. Except we were the ones who domesticated them in the first place.

Let's look at a simpler example: wolves. Are wolves necessary? Well, in many areas, wolves help keep deer populations at bay. What would happen if there were no more wolves? Well, deer populations would increase exponentially and eat through swathes of foliage in their region, limiting or wiping out multiple plant species in that area.
Then what would happen? Well, with their food sources depleted, the deer would be forced to migrate to a different region with adequate sources of food. Given enough time, their original area would regrow with the same or different plants. The deer might even come back one day. In fact, back when most of the world had not been colonized by humans, many grazing animals did this-- they would graze in one region until it was depleted, move to a different region, and then come back again when the first region had regrown.

So were the wolves really necessary? They served a purpose, yes, but things would have ended up fine with or without them.
