因为二氧化碳比空气要重，纯净的二氧化碳可以使人窒息。
Carbon dioxide in pure form can asphyxiate because it is heavier than air.
卡尔德拉说：“这些结果真正表明了植物对二氧化碳作出何种反应对产生准确气候预测是十分重要的。”
"These results really show that how plants respond to carbon dioxide is very important for making good climate predictions," says Caldeira.
二氧化碳泄漏会带来健康风险。 由于二氧化碳比空气重，因此可以在低洼地区和通风差的地区累积。
Spills would also be a health risk, since carbon dioxide is heavier than air, and so can build up in low-lying or poorly ventilated spots.
