Occasionally you read in the news that parasite x, plant y or animal z has been found in country abc which shouldn’t be the case and causes problems.
This is often a result of the ongoing climate change, increasing travel and global trade that allows many species to enter into new regions.
Because of the lack of natural predators or competitors, these new species can become locally dominant and replace established species.
My questions: what is the end game?
Will global biodiversity decline significantly to a few “core” species that are flexible in multiple climate zones or environment?
Or will the native species adapt or evolve further?
There’s no design, so there’s no intent. We can predict what might happen, which ecological areas will collapse, which species will thrive, and as humans we can intervene to try to prevent disasters we se coming. The “endgame” is the heat death of the universe, at which point all life will be long dead.
With humans spreading animals and plants (sometimes very intentionally) there is design and intent, and most often it’s dumb design and intent that didn’t work out.
See e.g. rabbits in Australia.
