It was actually about the Montreal Protocol and stratospheric ozone depletion.

它实际上是关于《蒙特利尔议定书》和平流层臭氧消耗的。

By-products created by the precipitation of the highest-energy particles nibble away at stratospheric ozone, which shields Earth from ultraviolet solar radiation.

最高能粒子沉淀产生的副产品会蚕食保护地球免受太阳紫外线辐射的平流层臭氧。

Using stratospheric ozone, or good ozone, in finishing is like putting a garment in the sun for a month, except we can do it in 20 minutes, Silla explained, and with a fraction of the energy or water the old process required.

新罗解释说，使用平流层臭氧，或称“良好臭氧”，在整理过程中，“就像把一件衣服在太阳下晒一个月，只不过我们可以在20分钟内完成，”只需消耗旧工艺所需能量或水的一小部分。
