When is the ozone layer expected to recover?

Answer 1

Not until long after Man is gone. Depletion could kill both Man and his food sources on the Earth's surface, which would itself reverse any forcing on Man's part towards depletion of the ozone layer. The ozone layer is self healing. Ozone constantly decays, and more is made by the Sun's UV-C radiation. But the equilibrium level of ozone is what controls how much UV-B reaches Earth's surface. Any damage (usually thinning, which allows more UV-B to reach the Earth's surface) to the ozone layer will be repaired when the contaminants that accelerate ozone's decay are gone / reduced. To entirely destroy the ozone layer would take: * dumping large quantities of sulfur compounds or water into the atmosphere, * entirely removing any molecules that contain oxygen from the upper atmosphere, or * the Sun to stop making significant amounts of UV-C or more energetic light. The ozone layer will extinguish entirely a few hundred years after the last plant has been killed. Until there is no oxygen left in the atmosphere, some ozone will form. The Sun entirely destroys the ozone in the atmosphere and continually renews it. But the race between ozone destruction by sunlight (providing protection), and destruction by contaminants is shifting the balance to contaminants... allowing more UV-B to arrive at Earth's surface... damaging any DNA it strikes.

The ozone layers will disapear if we dont save it

Answer 2

Well, I have no idea but Like i think it is like damaged so it might be there for a longgggg time and the only way to fix it is to go eco and tryy to keep the atmosphere clear so we wont have to damage more of it

Answer 3

Scientists hope the ozone layer will have completely recovered by 2060. Thanks to worldwide agreement and compliance with the 1987 UN Montreal Protocol (which agreed to phase out ozone depleting chemicals) global ozone depletion is no longer increasing. The Montreal Protocol is the most (some would say only) successful international agreement.

Answer 4

See "When will the ozone layer be gone?" in the "Related questions" section below.

Answer 5

It will take long. It depends on how we use CFC's.

Answer 6

The Ozone Layer naturally heals itself, but we are depleting it more than it can heal. We probably have 100 - 500 years I guess. Can't say for sure.

Answer 7

Some countries have banned the use of CFC which deplete ozone. So there is no chance of disappearing in the near future.

Answer 8

This is not a fixed year. It depends upon how we destroy the ozone.

Answer 9

The ozone layer is not sure to be destroyed. It depends upon how CFC's react in the ozone.
