Can the ozone layer repair itself?

Question

so yeah, once humans go extinct (I don't believe we will be living at this rate xD our fate is kind of eniditable) can the ozone repair itself once the pollution levels go down (you know when we all die xD )?

Answer 1

Yes, the Ozone layer will repair itself, but not very quickly with man around.

Answer 2

Yes, the ozone layer can repair itself surprisingly quickly. When scientists began to understand the effect CFCs were having on our atmosphere, there was some estimations made in the 1980s that the ozone hole above the Antarctic would close itself up by 2050. Unfortunately it's probably going to take longer than that because the scientists didn't realise how many sources of CFCs there are. Plus although CFCs have been mostly phased-out of the developed world, they are still being emitted from developing countries (and a new ozone hole may be opening above Europe).

This may seem like a bizarre tangent, but at the end of a geological peeriod called the Ordovician, 85% of species became extinct in a severe mass-extinction. One of the possible causes of this was a giant star exploding near the Earth, bathing us in radiation which stripped the ozone layer. Anyway, to try and understand this better, a few models have been constructed on supercomputers, and these have found that if human emissions didn't exist, about 50% of the ozone layer could regenerate in as little as 10 years.

Although I think that humans will be around (whether civilised or not!) for a long time yet... yes, the ozone layer is perfectly capable of repairing itself. Good news!

Answer 3

i don't think so. i'm pretty sure its like us. once we disappear, we'll never come back.

it won't matter as much anyways, except to the next life form living on earth. and they may adapt to the radiation and whatnot.
