why is it they have not tried to relocate some polar bears to the Antartica?

The Arctic and Antarctic are very different, climatically, except that both are very cold.

I believe Antarctica is colder than the Arctic.

The Arctic is water surrounded by land, and polar bears spend part of the year on the (warmer) land. Antarctica is land surrounded by water.

The water around Antarctica is *insanely* turbulent, due to the lack of land to slow it down, and kind of a vortex effect. I believe Arctic waters are much calmer.

And, even if the polar bears could somehow survive down there, it would put a great deal of stress on the (already stressed) penguin populations, possibly leading to *their* extinction. At best, a zero-sum game.

cuz they don't get along with penguins :P plus have you ever tried to move a polar bear?? From the north pole to the south?? They are set in the Arctic and will not want to be moved. And though the weather conditions seem similar they are very different. There is not the same wild life so the polar bears will have to adapt to new diets. over all it would be possble but difficult and we are not sure whether the result would be positive.

1) Because polar bear populations have been increasing for decade

2) Because polar bears in the antarctic would be considered an invasive species

3) antarctica has a completely different ecosystem which would be cruel to force a bear population unadpted to it to live in.

4) and finally the risk of unintended consequences is too great. Bermese pythons are not native to Florida but the ecological damage they are causing with the native wildlife populations because the snakes were introduced into an ecosystem devoid of natural predators to keep their populations in check

We shouldn't interfere with where mother nature placed the polar bears.

The Antarctica does not have the large area of sea ice that the polar bears use for their hunting grounds. There might be plenty of food for them, as you say, but I think the food sources might mind if the polar bears were successful and decimated their population.

Introducing animal species to different countries almost always end up as a catastrophe, often wiping out indigenous species.

Polar bears have an unfortunate habit of eating people and there are to many expeditions there. Tragedy would follow

Good idea .....lots of penguins to eat so we will see a polar bear population explosion, That will be enough for the denier industry to claim climate change science is a fraud

Everyone's a winner...except the ******* penguins

They seem to be doing okay where they are.

Global warming is fake

Oh my god! You sound so stupid! I just hope your joking...
