Yes! This is often forgotten,
No, it is never forgotten, it is well known by scientists.

Your choice of emotionally loaded verb is noted. And dismissed.
There is legitimate concern about the _rate_ of extinction. ComparedNope.
to the rates over the last four billion years, the modern rate is
many times larger.

The _rate_ of extinction is far greater now than at any time
in history (barring certain catestrophic events such as asteroid
impacts).

It depends. Could be that the return on investment by letting some small
insignificant species Z, in rainforest Y, go extinct is totally worth it.
No, it's not. How do you even compute the RoI for extinction events?
That's not what I said. Read again. Your naive question has been raised>>

We've never had as much food and as little famine on the planet than we
have today. So looking at the trends, we're actually doing better and
better.
That is not universally true. Where true, it is entirely attributed
to the use of fossil fuels to make fertilizers. Which will, inevitably,
run out. Then what?
