新的研究警告火箭发射可能会将地球正在恢复的臭氧层缩小3%。 New study warns rocket launches could thin the Earth's recovering ozone layer by up to 3%.

坎特伯雷大学的新研究警告说,火箭发射的大幅增加可能使地球臭氧层稀释多达3%。 New research from the University of Canterbury warns that a significant rise in rocket launches could thin the Earth's ozone layer by up to 3%. 目前,臭氧层正在从过去由氯氟化碳等化学品所造成的损害中恢复。 Currently, the ozone layer is recovering from past damage caused by chemicals like chlorofluorocarbons. 然而,由于每年发射约2 000枚火箭,火箭排放可能成为重大威胁。 However, with around 2,000 launches annually, rocket emissions could become a significant threat. 该研究强调需要减少使用含氯燃料和黑碳排放,以保护臭氧层,同时仍然允许空间工业成长。 The study highlights the need to reduce the use of chlorine-containing fuels and black carbon emissions to protect the ozone layer while still allowing the space industry to grow. 全球臭氧水平仍然比损害开始之前低2%左右。 The global ozone level is still about 2% lower than before the damage began.
