That is perfect. Look at them.
太好了你看他们
NARRATOR:Judging by their large size, this colony is all male.
从他们的个头来看这个应该是公的
TOONI:Look, the one that's just stuck his head up has got very short tusks,
你看刚刚抬头的那个牙齿就很短
which means it's quite young. He's younger, yeah.
也就是说他还很年轻他还很年轻
The one towards the back, you can see, is much bigger.
后面那个你可以看到的那个大多了
He's got much, much longer canines,
他有很长的犬齿
which means that he's a much older male.
也就是说他是很大年纪的公海象
PAUL:They grow to 40 years old, so he might be 30, 40 years old, that guy.
他们可以活到40岁那个家伙应该差不多三四十岁了
That big male there, he's got lots of cuts all over his chest.
那个公的他身上到处都是伤疤
Because they do use their tusks for fighting for establishing dominance.
因为为了生存他们总是会用他们的牙齿来打架
Let's do a count, roughly.
我们数数看
NARRATOR:The size of the colony will give an insight
那个牙齿的大小可以说明问题的
into the recovery of the species.
为了恢复这个种群…
TOONI:Okay, I can see
好我看到了
one, two, three, four...
1 2 3 4…
NARRATOR:They count 22 male walruses on the beach.
他们在沙滩上看到了22头公海象
The rule of thumb is that about a quarter of the colony will be on land.
凭经验估计应该有四分之一的海象已经上岸
The rest will be in the water, feeding.
其余的还在水中觅食
So this colony is 88.
所以应该是88头
That's about right.
应该是对的
They say between 1 0 and 1 00 in...
他们说在10到100之间…
Okay.
好
NARRATOR:Sixty years ago, this colony would have represented
60年前他们还是…
almost the entire walrus population of Svalbard.
斯瓦尔巴特群岛[挪威]的所有海象
They were made a protected species here in 1 952,
1952年后他们就成为了保护动物
and their numbers are slowly recovering.
他们的数量就在慢慢恢复
It's estimated there are now around 2,000.
现在都差不多2000多头了
I love how they're, you know, on this great expanse of beach,
我希望看到他们在沙滩上的样子你知道的
they're all collected in one group,
他们总是群体出动
and they're just lying all over each other and...
他们总是相互挤压着…
They're very social, aren't they?
他们是群居生活的不是吗？
They're very communal creatures. Yeah.
他们是群居动物 - 是
NARRATOR:As the Arctic transforms, the Atlantic walrus could,
随着北极环境的变化北极海象可能…
in the short term, be a climate change winner.
在短期内随着冬天气候的变化
As their feeding grounds are usually near land,
因为他们的繁殖是需要陆地的
they're not dependent on ice floes to help them reach their food.
他们是不依赖冰川来寻找食物的
And the retreating ice could expose more feeding grounds
冰川的融化会带来更多的食物
and stimulate the growhh of clams, their staple diet.
海澡会繁衍那是他们的主食
Which means that there's plenty of opportunity
那就是说会有跟多的机会
for their population to keep on and on increasing.
他们的种群数量会不断增多
NARRATOR:At least initially,
至少会慢慢增多
global warming could improve the Atlantic walrus' ability to survive.
全球变暖会增加大西洋的海象数量
It's a real interesting balance,
这是一种有意思的平衡
because we talk a lot about the negativity of climate change,
因为我们谈到了很多气候变化的坏处
but it is always nice to have that little bit of a counterbalance
但是有了这个平衡还是要好很多
to be able to say, ''You know what?
你还会说你知道什么？
''There are some creatures that might benefit in some way
那有一些种族都要灭绝了
''with the changing Arctic climate.''
随着北极气候的变化
NARRATOR:The changes in the Arctic Ocean are complex,
北冰洋的气候变化是很复杂的
and not always predictable.
都是无法预料的
But what we do know is that they will affect us all.
但是我们知道他们是一定会影响到我们的
A transformation in this remote, bitter ocean
这个偏远地方的变化…
will have a profound effect on life and climate around the globe.
会影响到全球的气候
As the team has journeyed across the world's oceans,
当探险队看完了全球的大海之后
change has been the dominant theme, often triggered by human activity.
变化是主旋律都是因为人类的活动
Habitats are being destroyed.
栖息地被毁坏了
Something so perfectly adapted to one particular ecosystem,
有的恰好适合另外一个生态系统
it's got nowhere else to go.
没有别的去处
NARRATOR:Species are being threatened.
很多种群面临威胁
We are totally decimating their numbers.
是我们让他们的数量在减少
NARRATOR:And the fragile balance of life is being disrupted.
生态平衡被打破了
PHILIPPE:They'll eat their way down the food chain
他们会吃食物链的下一种生物
till there's nothing left down there.
直到没有东西可以吃为止
NARRATOR:But there are also signs of hope.
但是也还有希望
Some species are managing to adapt and are thriving.
有很多种群已经适应新的环境而且还很旺盛
And with human ingenuity, we are attempting to restore the balance.
利用人类的智慧我们正在恢复这些平衡
TOONI:What we're looking at here is almost
你在这儿看到的…
the Indian Ocean equivalent of a garden centre.
就跟印度洋上的花♥园♥差不多
NARRATOR:The oceans are one of our planet's greatest assets.
海洋是地球上最为重要的资产
And their future is in our hands.
