We are not anywhere close to having any of that at required scale.

And when we do, it will be nowhere near existing biodiversity for a long-long-long while (if ever).

And we are also nowhere near doing that at scale from scratch. We need existing living breathing species to do anything.

And even then it's a problem when "new kind of fish" ends up destroying a different kind of fish [1] etc.

I won't even go into how bees are needed for so much more than just crops.
