The mountains of Appalachia have lost 90 percent of their red spruce forests to logging and coal mining.

由于伐木和采煤，阿巴拉契亚山脉失去了百分之九十的红云杉林。

That’s good because red spruce forests like this one excel at taking planet warming carbon dioxide out of the atmosphere and locking it away in the soil.

这很好，因为像这样的红色云杉林能够把使地球变暖的二氧化碳带出大气层，并将其固定在土壤里。
