In the fall and spring, ozone covers the entire planet. When it is winter at one of the poles, an ozone hole forms since there is no UV-C from the Sun to make more ozone.
as we know there are 2 holes in the ozone layer, over Asia and another 1 over the north pole - it is all apart of god's plan. so don't go freaking out if there is a hole. god knows what he is doing. everything is for a reason...
As an indicator of ozone layer health, the "ozone hole" was at near record size last year. No real indicator that the ozone layer is healing. But if someone doesn't jump up and down on the panic button continuously, it is very easy for the anti-greens to make up snide remarks like the one shown above. Please see the link below for an ozone layer watch site.
The ozone hole was first thought to be an unnatural phenomenon, and we got all worried about that. Once we monitored the size of the ozone hole and how that seemed to increase each year, and once we monitored the UV-B radiation incident on the surface of the Earth, then we had a measure of ozone depletion. These measurements started in the early 1970s, with expectation of a positive result probably by the mid to late 1990s (with solar cycles contributing to fluctuations in ozone, and that is an 11 year cycle). So I'd guess 1995 or so. See the link below for more information.
Life. Its everywhere. The ozone layer protects surface life. If we could only get rid of that pesky ozone layer, then the Sun could kill us all, and the problems would all go away. You could say that the ozone layer "causes" the problem of politics, religion, the disagreements in the Middle East, everything associated with Man. How you ask the question changes the answer you get...
Excessive ozone in the ozone layer will decay rapidly to near current levels. It is unstable and breaks down with time. It would take a catastrophic event to make too much more than we currently do. If the ozone layer stayed where it was, and got twice as thick, then we'd have less UV-B striking Earth's surface, fewer cataracts, fewer melanomas, probably higher crop yields. We would also face extreme global warming as ozone is a greenhouse gas. The cooing of the Antarctic is being blamed on the thinning of the ozone layer, for example. If the atmosphere thinned, and the ozone layer was forced lower, then high levels of ozone (such as peak levels found in the ozone layer) would likely kill most life on Earth in a few decades. Mice that were forced to breathe such levels of ozone for even a day fared very poorly. Ozone is a very strong antiseptic. It is even good with humans for this purpose, so lo level ozone is not a good thing. The ozone layer is amazing resilient though. The "hole" in the ozone layer appears twice each year during each poles winter. This is due to the lack of sunlight. Once the sun returns, the hole disappears very quickly.
The ozone layer has a growing hole yes.

no he has a hole a big hairy hole lolmiley Cyrus is cooler than Dave gorrol)

If the ozone layer got thinned, UV will enter the earth. They are fatal rays of the earth.

A hole where it sat until somebody got up the hueves to dump it out.
he sailed aroun the hole world but right before he got killed
The 1987 Montreal Protocol got all countries to agree to phase out chlorofluorocarbons (CFCs) which were then used in aerosol sprays and refrigeration. Chlorine from CFCs destroyed ozone in the ozone layer which led to the weakening of the layer. Now in 2012 scientists believe that ozone seems to be no longer being destroyed, but it will take up to 2060 before the ozone layer has repaired itself.

The ozone depletion is mostly over poles. It is due to the low temperature at the poles.
