关键的问题是，土壤释放出更多二氧化碳，是否因为植物生长更快，从而吸收了更多二氧化碳；是否因为土壤释放了应该在低温下保留在土壤里的二氧化碳。

The critical question is whether soils release more CO2 because faster-growing plants pump more in, or if soils release CO2 that would have stayed in the ground at lower temperatures.

最后，要是你发现你需要一种比常春藤还要耐寒的植物，试试动手做一个可以在超低温下生存的苔类景观箱吧。

Finally if you find that you need something even more chill than Ivy, try your hand at making an ultra-low maintenance moss terrarium.
