If Arctic melting will result in harm to the species by 2100, is there any good reason why they should not be introduced to the Antarctic? There's a lot of seals and penguins down there.

The Antarctic is melting too.

They are very different places. The Arctic ice is just yards thick and all afloat, the Antarctic ice is miles thick and all on a continental landmass except the fringes. I've never seen an estimated date for the end of the Antarctic ice but it must be thousands of years off. The Arctic will be ice-free at mid-summer in mere decades. The problem the bears have is the time it will take to start the annual re-freeze after they've been forced onto land each summer.

Rabbits in Australia?

The survival of polar bears is an essential, and the rabbits were never endangered.

This is heartbreaking to me.

Let's find someone to blame.

Henry Ford.

Any improvement on Henry Ford, or are we settled.

Before you ask, every name I come up with will be an American capitalist. No country on earth has ever put more man-made constituents into the atmosphere. I would happily see a Crimes Against Life tribunal sit in judgement on the perpetrators and their successors.

Watch me not argue with that!

You ask for reasons why we should not introduce polar bears into an ecosystem to which they are not native and I gave you an example of the damage that could do. I was not suggesting that rabbits were as endangered or as important as polar bears.

Ah.

I was suggesting that any practically believable damage is more than offset by the potential benefit to the bears. We could make a scale of desired outcomes. Penguins and seals will continue to live elsewhere. I would find it hard to imagine that the bears would leave none. I'm sure it could be modelled first.
