And I think particularly now,
我認為尤其是目前，
as we see ourselves in a time of environmental crisis,
我們明白人類身處環境危機時代，
we can learn so much from these people who have lived so sustainably in this ecosystem for over 10,000 years.
我們可從這些族群身上學到許多東西他們在這片生態系統中生活了1萬多年。
In the heart of this ecosystem is the very antithesis of all of these values that we've been talking about,
這片生態系統蘊含的核心價值與我們目前追求的目標大相徑庭，
and I think these are some of the core values that make us proud to be Canadians.
我認為其中某些核心價值令身為加拿大人的我們引以為傲。
This is the Alberta tar sands,
這是阿爾伯塔省油砂礦，
the largest oil reserves on the planet outside of Saudi Arabia.
它是世上石油蘊藏量最豐富的地區，除了沙特阿拉伯之外。
Trapped underneath the boreal forest and wetlands of northern Alberta are these vast reserves of this sticky, tar-like bitumen.
在北方森林及北阿爾伯塔省濕地下方蘊藏著大量粘稠、似焦油的瀝青。
And the mining and the exploitation of that is creating devastation on a scale that the planet has never seen before.
挖掘及開采這些礦脈的舉動對地球造成史無前例的破壞。
I want to try to convey some sort of a sense of the size of this.
我試著說明這些破壞的規模。
If you look at that truck there,
以圖中的卡車為例，
it is the largest truck of its kind of the planet.
它是同類卡車中最大的一種。
It is a 400-ton-capacity dump truck and its dimensions are 45 feet long by 35 feet wide and 25 feet high.
承載量達400噸的砂石車規格為45英呎長，35英呎寬、25英呎高。
If I stand beside that truck,
如果站在卡車旁，
my head comes to around the bottom of the yellow part of that hubcap.
我的頭部大約只到黃色輪框蓋底部。
Within the dimensions of that truck,
在這輛卡車體積范圍內，
you could build a 3,000-square-foot two-story home quite easily. I did the math.
你可輕易建造一棟 面積3000平方英呎、兩層樓高的房子，我曾經計算過。
So instead of thinking of that as a truck,
因此，與其將它視為一輛卡車，
think of that as a 3,000-square-foot home.
不如將它視為一棟 面積3000平方英呎的房子。
That's not a bad size home.
一棟不小的房子。
And line those trucks/homes back and forth across there from the bottom all the way to the top.
這些卡車在這片區域中來回奔馳從底部直到頂端。
And then think of how large that very small section of one mine is.
想象一下這片區域的大小，這僅是礦場的一小部分。
Now, you can apply that same kind of thinking here as well.
現在，你可將同樣想法運用到這片區域。
