Record sized Antarctic ozone hole in 2007, near record in 2008, 2009 season yet-to-occur.
The ozone hole heals when it is not winter at either the north or south pole. But the ozone layer is where UV-B is or is not absorbed by the amount of ozone along a vertical path. Ozone is still allowing more UV-B to arrive at the Earth's surface, so it appears that the ozone layer has not healed itself.
The ozone layer is self-healing. Depletion means that it gets thinner at equilibrium, when contaminants destroy ozone before sunlight gets a chance to. A way to measure the average thickness of the ozone between the Sun and any point on Earth's surface is to measure the amount of UV-B that arrives at a sensor at the surface. The size of the ozone hole is another indicator.
There is no indication that the ozone layer will reach some catastrophic failure point. So far it has shown to be a slow decrease in available ozone to block UV-B, allowing more UV-B to reach Earth's surface.

What can you do to change the situation with the ozone layer?
Ozone layer is depleting. To protect it must curb the use of CFC's.
Why is the ozone layer named the ozone layer?
Ozone layer contains ozone in it. Therefore, it is named so.
What planet includes a layer of ozone?
Earth has a layer of ozone. It is present as the ozone layer.
A layer of the ozone in the protects from earths radation?
Ozone is a layer which protects us. Actually ozone is just a gas, ozone layer is the layer.
Which part of atmosphere screens out the harmful radiation from sun?
the ozone layer is the the part of the atmosphere that screens out harmful radiation from the sun.

Ozone layer is depleting. To protect it must curb the use of CFC's.
What is the current situation of our ozone layer?
Weakening - but still doing its job.
Why is the ozone layer named the ozone layer?
Ozone layer contains ozone in it. Therefore, it is named so.
What is the formed of ozone layer?
Ozone layer is formed of ozone. It is a gas.
What planet includes a layer of ozone?
Earth has a layer of ozone. It is present as the ozone layer.
What do you call damage to the ozone layer?
damage to ozone layer is called ozone depletion. It is thinning of ozone layer.
A layer of the ozone in the protects from earths radation?
Ozone is a layer which protects us. Actually ozone is just a gas, ozone layer is the layer.
What are the layer of gases that surround the ozone layer?
The layer of gases that surround the atmosphere is ozone. It is present as the ozone layer.
What is the ozone layer and how are humans altering it?
Ozone layer is the layer of ozone. Humans are altering it by CFC's.
What is the layer of the atmosphere that inclides the ozone layer?
The ozone layer is in the stratosphere. It is a pool of ozone molecules.
Which part of atmosphere screens out the harmful radiation from sun?
the ozone layer is the the part of the atmosphere that screens out harmful radiation from the sun.
What planet has a protective ozone layer?
Earth and Venus have a protective ozone layer. These planets have ozone molecules in ozone layer.
