This is one of the reasons why it's called  这正是它被称为

the world's dirtiest oil.  世上最脏油类的原因之一

It's also one of the reasons why it is  这也是使它成为

the largest and fastest-growing single source  加拿大最大、增长最迅速的

The tailings ponds are the largest toxic impoundments on the planet.  那些残渣池是世上最大的毒性蓄水池

Oil sands -- or rather I should say tar sands --  油砂－或者我该称它为沥青砂－

"oil sands" is a P.R.-created term  “油砂”是公关部门创造的词汇

so that the oil companies wouldn't be trying to promote  使石油公司不至于像是推广

something that sounds like a sticky tar-like substance  某种彷佛沥青般黏稠的物质

that's the world's dirtiest oil.  或世上最脏的油

So they decided to call it oil sands.  因此他们决定称它为油砂

The tar sands consume more water than any other oil process,  沥青砂的生产过程比其他油类消耗更多水

three to five barrels of water are taken, polluted  生产一桶原油需使用三至五桶水，受污染的水

and then returned into tailings ponds,  进入残渣池

the largest toxic impoundments on the planet.  成为世上最大的毒性蓄水池

in just one of their tailings ponds,  在他们拥有的其中一个残渣池中

dumps 250,000 tons of this toxic gunk every single day.  每日倒入25万吨毒性黏稠物

That's creating the largest toxic impoundments  创造出有史以来最大的

in the history of the planet.  毒性蓄水池

So far, this is enough toxin  目前为止，其中的毒性物质

to cover the face of Lake Eerie a foot deep.  足以覆盖伊利湖面一呎深

And the tailings ponds range in size up to 9,000 acres.  残渣池的面积可达9000英亩

on stream to be approved soon.  很快就会获得批准

And of course, these tailings ponds --  当然，这些残渣池－

well, you can't see many ponds from outer space  确实，你无法从外太空看见许多残渣池

and you can see these, so maybe we should stop calling them ponds --  但你可以看见这些 因此或许我们不该称它为“池”－

these massive toxic wastelands are built  这些大型毒性废料池并未装设

unlined and on the banks of the Athabasca River.  防护措施，散布于阿萨帕斯卡尔河沿岸
