Yeah I wouldnt say "whales making comeback - well done" when we pushed them to the brink.
Yes some new species maybe happening, but it would be at a tiny rate. Especially in larger mammals - which we are managing to wipe out.
And is it a big deal if domesticated animals are on the rise? More chicken, cattle, pigs, dogs, cats than ever in the history of the planet. Thats volume, not diversity.
Ditto with plants.
And wow - we might double the number of species in the next million years. And lets be honest - in a million years we would have the technology to just gene-make new species. Or have been replaced by AI and maybe no organics.
We also might greatly reduce it. Again especially at the "large end of town". A hundred new insects probably doesnt really make up for losing primates.
Ahh in the end he does say that counting/estimating new species needs to be studied.
But I think its a long way from "she'll be right"
