when will the ozone layer be too thin to survive?

Answer 1

The ozone layer will never be too thin to survive. That's based on the faulty assumption (that's tought in public schools and propagated by environmentalist groups - I don't know why) that the ozone layer is just a tiny little thing that was put there that we're destroying.

That is COMPLETELY incorrect. This is how the ozone layer works:

1. In the upper layers of the atmosphere, you have two types of oxygen - elemental, which is just one atom of oxygen, and molecular, which has two atoms joined together. When these get struck by ultraviolet light, they join together and form ozone, which is just three oxygens combined.
2. When the ozone gets struck by ultraviolet light, it breaks apart again and the process repeats

So, if there is an ozone hole (and the amount of UV light stays the same), more ozone will just be made and it will repair itself.

The "ozone hole" occurs when the seasons change because there is not enough UV during the winter to create the ozone or when winds change because the ozone molecules can get blown out of the area.

We really cannot tell if humanity has created an ozone hole because we only started measuring the amount of ozone this decade so we have nothing to compare it to. Maybe there has been an "ozone hole" for centuries. We don't know. Just because there's not as much ozone in an area does not mean that it is something we did or that something's wrong with it. We're just comparing ozone layers to what we assume they should be (based on the assumption that ozone will be equally distributed everywhere), and, when it's not, it's a hole. Swiss cheese would be considered defective if you falsely thought that all cheese should be solid. Same deal

Answer 2

I don't think it will ever be too thin to survive. As i understand it, Ozone holes open and close routinely and it just mean that more
harmful UV rays from the sun get in. So just ladle on some more sun-block and you'll be fine...by the way, you're very out of date. The
"We're all gonna die because of the Ozone layer" panic was in the 80's and 90's (before that it was "We're all gonna die because of the coming Ice Age" and now it's "We're all gonna die because of Global
Warming"...Oh I forgot the "We're all gonna die because of world over population"...I think that was the 60s.

Answer 3

The ozone layer itself, if you laid it on the ground, is only about as thick as a piece of canvas.
That said, in the past couple of decades, since the reduction of CFCs used domestically and industrially, the ozone layer has actually been 'healing' itself.

That said... mankind would still survive without it, although there would be a lot of changes required. A lot more of life would need to be spent indoors, and since vegetation would suffer (unrelenting UV light would kill off a lot of plant life) we'd need to start growing plants and such indoors as well.

Answer 4

It would be hard but we would survive. The ozone layer helps to shield us from the sun harmful radiation, the earths magnetic Field does most of the work thought. You should be more worried about the earth molten center cooling, when that happens bye bye magnetic field, and bye bye us.
