But close to the equator, where there is constant warmth and water, there are grasslands close to paradise.
而在赤道附近，阳光和水资源得到了保障，这里有着天堂般的广袤草原。
This is the most bio-diverse grassland in the world... the Cerrado in Brazil.
这是世界上生物多样性最丰富的草原，巴西的塞拉多草原。
Here there are thousands of species of both animals and plants found nowhere else.
这里孕育着成千上万种独特的动植物。
A rich and complex community that is kept in balance by this ghostly creature. A maned wolf.
这个丰富多样的群落想要保持生态平衡，便不能缺少这种幽灵般的生物。鬃狼。
Quiet and shy, it's little known and seldom seen.
鬃狼安静而腼腆，它们鲜为人知，较为罕见。
Unlike any other wolf in the world, their diet is mostly vegetarian.

And they particularly like lobeira fruit.

This plant increases the fertility of the land, and helps to sustain the entire Cerrado.
这种植物可以增加土壤肥力，并有助于塞拉多草原的稳定。
The maned wolves, odd though it may seem, are, in effect, the gardeners of these unique plains.
尽管鬃狼看起来不像，但实际上它们是狼果这种独特植物的园丁。
The dense grass in turn provides this female with a comfortable home and somewhere to hide her three puppies, just one month old.
茂密的草丛反过来为这只雌性鬃狼提供了一个舒适的家，以及一个可以隐藏三只刚出生幼崽的地方，它们只有一个月大。
She is so rare that she's been fitted with a radio-collar so that scientists can study her continuously.
鬃狼过于罕见，因此这只雌性鬃狼被戴上了无线电项圈，方便科学家进行持续的研究。
And our remotely controlled "den camera" reveals a mother only comes here for a few hours a day to suckle her pups.
根据我们的遥控"巢穴摄像机"显示，一天中，雌性鬃狼在巢穴中哺乳幼崽的时间只有数小时。
She spends much of her time foraging to provide for her growing family.
它将大部分时间都花在觅食上，以供养日益壮大的家庭。
Now, alone in the den, her puppies are suddenly in danger.
此时，单独留在巢穴中的幼崽突然陷入了危险之中。
Not from other predators... but from fire.
危险并非来自于捕食者，而是来自于火灾。
Their home is being burnt all around them. These fires can race through a mile of grassland in a matter of minutes.
它们的家园燃起了熊熊大火。火情可以在数分钟内蔓延至近两公里以外。
The Cerrado devastated. Why?
塞拉多草原被摧毁了。火灾原因是什么呢？
In order to clear land to grow crops.
是人类为了开垦土地种植庄稼。
This particular fire didn't reach their den. But it's empty.
这场大火没有波及到它们的巢穴。但巢穴里空空如也。
This time, the family were lucky.
这一次，这一家子鬃狼很幸运。
But her species faces an alarmingly uncertain future.
但整个物种正面临着令人担忧的不确定未来。
At the current rate of habitat destruction, these may be some of the last maned wolves to survive in the wild.
按照目前的栖息地破坏速度，这些可能将是最后一批生存于野外的鬃狼。
