In regards to humans and animals - even with our ozone layer, we can't stare at the Sun for more than 60 seconds without risking blindness - with a 100% decrease of ozone, blindness could also set in immediately.

对于人类和动物来说——在有臭氧层的情况下，我们盯着太阳超过60也会有失明的危险——因此一旦臭氧含量100%下降，我们也会立即失明。

Right. So in this headline, it's saying that if nothing changes, if everything carries on the way that it is now, then the Earth's ozone layer — this protective shield — will have recovered by 2066.

错。因此，在这个标题中，它说的是，如果什么都不改变，如果一切都照现在这样进行下去，那么地球的臭氧层——这个保护层——将在 2066 年恢复。
