Can the atmosphere be repaired

Theoretically, yes. We know the chemical composition of the atmosphere, and we can synthesize it in the lab, so with enough money and government support, the technology shouldn't be a problem.

But while we know the composition of the atmosphere, we don't know the complex patterns of change, and the atmosphere is so big that it's questionable whether this small effort will work. Moreover, it has only been experimented with in the laboratory, and it is questionable whether it can be applied on a truly large scale.

No matter what the situation, nature is always very strong, and what we need to do is not to think about how to repair after the damage is done, but to protect nature from now on
