Changing Antarctica 南极海洋生物与环境变化




Changing Antarctica 南极海洋生物与环境变化



有关 “survival(生存)” 的词汇


What is the temperature of the ocean around Antarctica?


Antarctica is the most extreme continent on Earth. Few animals can survive the bitter cold. But one Antarctic environment is surprisingly stable - the ocean. But it is cold - minus two degrees centigrade.


Like everywhere else in the world, the Antarctic environment is changing. In some places the water is already warming - a huge challenge for animals that have never experienced any change.


Justin Rowlatt, BBC correspondent
So some of the incredible Antarctic animals are in this tank. Now Anne Todgham is a marine biologist; you've been studying these animals for years…

So they have anti-freeze proteins inside of them that keep them from freezing. They have different red blood cells that are in fact not red. They have compensated for the cold, so they can go about their daily lives and actually thrive in an environment that most animals will find very stressful.

The big question for Anne is how well these extraordinary creatures will be able to adapt. The results so far are not promising.


Dr Anne Todgham, Associate Professor, University of California Davis
I am actually pretty worried, I wish the data was wrong, I wish I didn't have to be worried. But you know there are a lot of things that are going to change in the ocean, and these animals are being stressed to their max.

You may wonder why we should worry about the fate of a few unusual species, but the scientists here say we should think of what's happening as a warning. If these animals can't survive in our changing world, what does that say about our future?
