what are the recommendations by the scientists regarding the ozone problem?

A simple answer is avoid polluting the air, if go into details avoid releasing gases like CO, CO2, HFC contents (scuh as halon, freon) in to air, avoid cutting trees, the most important is to reduce pollution did u heard about Kyoto protocol in that almost all the countries signed a pact to reduce industrial emissions but lated USA quit from it saying that it affects their industry.

This is complex issue without consensus in the scientific world.  Getting away from the politically correct interpretations is the following:\n\nFor years, the ozone depletion-impact crowd was worrying about the effects surface ultraviolet radiation would have on the Antarctic ecosystem—though, as we’ve said before, the Antarctica ecosystem, except for a few penguins, consists entirely of scientists studying the ozone hole.\nThis year (and it has happened before), the National Aeronautics and Space Administration (NASA) reported the infamous hole (which is not really a hole at all but a reduction in total column ozone) has spread over a populated area: Punta Arenas, Chile. Chilean health officials warned people to remain indoors during the high sun periods as ozone levels there dropped to about 175 Dobson Units (a measure of the total amount of ozone in the atmospheric column above any location). Similarly low values were occurring over and surround Antarctica.\nQuickly, David Hofmann, director of the Climate Monitoring and Diagnostics Laboratory of the National Oceanic and Atmospheric Administration (NOAA), countered that though the hole is large, the severity of the ozone depletion within that hole was comparable to ozone levels measured over the past few years.\nThen, the World Meteorological Organization, which measures ozone depletion slightly differently, spun its own ozone yarn, declaring that the end of September’s depletion was the worst on record. But once again, as is unfortunately common with most environmental news, this is much ado about nada.\nFirst, the size, shape, and amount of ozone depletion are significantly affected by the weather. The Antarctic stratosphere was cold this past winter (global warming?), which resulted in more depletion than normal. That minor factoid was buried in the last paragraph of CNN’s coverage of this nonstory.\nAs NOAA’s Hoffman explained, “year-to-year fluctuations in the geographical size of the ozone hole and the timing of the ozone production are believed to be related to meteorological factors such as temperature and winds, rather than further increases in ozone-destroying chemicals in the atmosphere.”\nSecond, if these levels of ultraviolet radiation seen in Punta Arenas were truly harmful, most of the world’s population would be in grave danger. Most of us, on a regular basis, are exposed to solar radiation far more intense than that seen in southern Chile.\nAn index of global ultraviolet light levels, assuming cloud-free and unpolluted skies, was constructed for October 11, the same day as the 175 Dobson Units reading in Punta Arenas. The UV index there of around 9 is much lower than UV levels across more than half of the planet. Most places receive more intense solar rays than Punta Arenas does.\nThird, the expanded ozone hole is short-lived. By November, as Antarctica warms, the vortex of winds that effectively isolate Antarctica from the rest of the planet weakens, and high ozone levels over the rest of the hemisphere quickly fill the so-called hole. That process only serves to highlight the climatological uniqueness of the situation over Antarctica.

You could do a report on how Ozone O3 is created and how much energy it needs.  Also how it is broke down.

Ozone (O3) reflects/scatters ultraviolet radiation back into space.  However, if it is depeleted, this radiation makes it past the atmosphere and down to the surface.  The amount of shorter wavelength (higher energy) radiation passing through the atmosphere would increase, causing higher mortality rates from skin related ailments and can also destroy plant tissue.  Also, this radiation would heat the earth more since it carries more energy with it.  This is not usually a problem, since this thermal radiation currently passes back into space.  However, with pollution clouds/dust being more prominent, it would reflect the thermal radiation back down to earth's surface, driving the temperature up even more.

The previous answer is incorrect that there is no relation between the two problems. UNEP reports that global climate change may be slowing the healing process of the ozone layer. Warming of the atmosphere near the earth's surface actually causes cooling of the stratosphere and the cooler temperatures accelerate the chemical reactions that destroy ozone molecules.  Further, the US EPA reports that increased levels of ultraviolet-B radiation can be expected to worsen global warming by reduction of plant and phytoplankton populations. The two problems are tied in complex ways that involve feedback from both systems affecting the other. \nHere is the US EPA booklet:\nhttp://www.epa.gov/ORD/WebPubs/stratoz.pdf\n\nThe UN formed the UN Framework Convention on Climate Change that resulted in the controversial Kyoto Protocol in 1997.  The UN has an excellent website that gives details on the history, the text of the protocol, some of the science, and status. \nhttp://unfccc.int/2860.php\n\nThe UN is also involved in trying to solve ozone depletion. In 1987 the Montreal Protocol was signed by international parties. They agreed to phase out chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform usage which all cause ozone depletion in the atmosphere. These chemicals are used in dry cleaning, fire extinguishers, and in refrigeration. Many of these chemicals had begun phase out in the United States prior to the protocol due to EPA regulations. The UN's World Meteoroligal Organization and UNEP sponsor assessments of the ozone hole regularly. \n\n\n\nWhile the Montreal Protocol produced positive results during the late 1990's the problem has recently gotten worse- and then improved again!. Here is a NOAA graph showing that:\nhttp://www.cpc.ncep.noaa.gov/products/stratosphere/sbuv2to/gif_files/ozone_hole_plot.png\n\nThe US EPA has an impressive list of links to ozone depletion information. \nhttp://www.epa.gov/ozone/science/#specinfo

Knowledge is the way of improvemet We can find the way in which we can change our mother Earth very Drastically.\n\n Scientist learn from other planets/Star and Satelites that how they are come to end what are the reasons and all..\n  \n Last !!!  Due to Research in Space only we come to know HOLE in OZONE layer now we can take some action to prevent this.

Posts here are generally on the right path.\nThe ozone hole is actually a NATURAL phenomena.  It occurs every year over Antarctica because of the cold weather and circulation patterns there.\n\nHowever, the hole was shown to be getting larger the past few decades.  This is primarily due to the use of Chloroflorocarbons... propellants in spray cans.  As most of the world has found replacements and usage has dropped, the damage is beginning to decrease.  However, CFCS have a resident time in the atmosphere of about a century... so it is believed the effects will continue to linger for a while before relaxing.\n\nI just found this link:\nhttp://ozonewatch.gsfc.nasa.gov/\nwhich allows you to keep tabs on the current hole and see how it compares to previous years.  It appears the area of the hole has grown larger the past few decades... but the intensity of the minimum has decreased.  So it depends upon how you look at it!\n\nWish you well,\nGod bless,\nShane

actually, this is one problem that has actually been helped by government.\n\nan international agreement known as the montreal protocol signed in 1988 has restricted the use of ozone depleting chemicals like chlorofluorocarbons, methyl chloroform, methyl bromide and the like.  atmospheric monitoring has shown that the levels of these chemicals in the atmosphere has started to turn over and decline.\n\naccording to the NOAA report on ozone depletion published in 2002, "Chemistry-climate models predict that springtime Antarctic ozone levels will be increasing by 2010 because of projected decreases of halogens in the stratosphere.  A return to pre-1980 total column ozone amounts in the Antarctic is expected by the middle of this century."\n\nso, in other words, we only have to keep doing the right thing and not using the chemicals which we know deplete the ozone, and the earth will heal itself by 2050.  cool eh!

the ozone layer keeps the earth a stable temperature.

I am very concerned with the rash of natural disasters that are happening and can only really attribute them to global warming. Our planet has the ability to "rebuild" the ozone, but not quickly enough at the rate we are depleting it. I think as Americans and as a consumer nation, we need to get on the clue train about how much we are harming our world by car emmisions and we need to switch to a clean alternative. It's possible, but we fear change.

The Recipe For Ozone Loss\n\nTo summarise then, we have looked at the 'ingredients' or conditions necessary for the destruction of ozone that we see in Antarctica. The same applies more or less to the loss of ozone in the Arctic stratosphere during winter. Although in this case the loss is not nearly so severe.\n\nTo recap then, the requirements for ozone loss are:\n\nThe polar winter leads to the formation of the polar vortex which isolates the air within it.\n\nCold temperatures form inside the vortex; cold enough for the formation of Polar Stratospheric Clouds (PSCs). As the vortex air is isolated, the cold temperatures and the PSCs persist.\n\nOnce the PSCs form, heterogeneous reactions take place and convert the inactive chlorine and bromine reservoirs to more active forms of chlorine and bromine.\n\nNo ozone loss occurs until sunlight returns to the air inside the polar vortex and allows the production of active chlorine and initiates the catalytic ozone destruction cycles. Ozone loss is rapid. The ozone hole currently covers a geographic region a little bigger than Antarctica and extends nearly 10km in altitude in the lower stratosphere.

"Are we destroying the earth with technology or is the earth doing business as usual"\nI suggest you track the changes scientists have found in the entire history of the earth, warming, freezing, wet and even effects of smoke from Krakatoa. Then compare what is happening now with pollution and the depletion of the ozone layer and ask the readers to make their own conclusion.

the only way I can see this, is to disolve ozone (O3) into water. Ozone is already used to disenfect chirgical tools
