Day: Right on top of this, the stuff you scraped off to get the oil sands, the first layer of oil sands, there was a very delicate balance of spongy, boggy, scrubby trees and things, which you can't replace or which will take centuries or aeons to replace, won't it?

德：另外还有一点，你们为了采到这些油砂，会把地表的第一层油砂挖去，而这一层松软多孔易吸水，包括了沼泽、灌木丛、树木和其他物质，它们形成了一个微妙的平衡，但你根本无法替代这种平衡，或者需要几个世纪甚至永远才能恢复这种平衡，是这样吗？
