Elephants are great travellers

大象喜欢迁徙

and here, in this part of Kenya,

they regularly moved from the lowlands up the side to the mountains

他们定期从低地迁到山坡

to feed in the forests up there.

去森林里觅食

But then, the human population of Kenya grew

然而 随着肯尼亚的人口增加

and roads like this one were constructed,

人们建立了类似这样的公路

penning the elephants down in the lowland,

使大象被围困在低地里

where they created havoc amongst the farms.

他们在那里大肆破坏农场

Not only that, there were danger of collisions on the road.

此外 他们还面临着与车相撞的危险

And then someone suggested building an underpass.

于是有人提出建造一条地下通道

Within 24 hours of it being completed,

完工后的24小时内

one elephant had passed through.

一只大象穿过了通道

And now, all the elephants use that route

如今 所有大象都常在晚上

to go up the mountain, often at night, to feed.

通过这条路上山觅食

Simple ideas like this underpass

are a lifeline for these elephants,

却为大象构建了生命线

especially in times of drought.
