We have governmental agencies that are set up to hide this fact from the population or to mask it. We have all the data being skewed to hide the severity of what is happening from the population for as long as possible.
Further investigation found that the ozone layer was being destroyed because of the release of chlorofluorocarbons CFCsmostly in the northern hemisphere.
The CFCs once released from anthropogenic processes, spread throughout the world and diffused into Slogan on ozone upper atmosphere, where they are broke down to release chlorine. This chlorine was able to take part in complex catalytic chemical reactions which was destroying ozone leading to the creation of the ozone hole.
Once the science was clear, nations around the world began taking measures to phase out the use and release of CFCs. Ozone pollution in the troposphere and its destruction in the stratosphere and all other air pollution is mainly the result of human activities.
The small things you do every day can help reduce air pollution and hence improve the protection of the environment as well as human health.
Life on Earth depends in part on a thin shell of gaseous ozone that stretches from about 10 to 25 miles above our heads, encompassing the planet like an invisible, protective shield. At this altitude, it lies well above the height at which normal commercial aircraft fly, and far beneath the orbital paths of spacecraft.
The ozone layer is the main barrier between us and the hazardous ultraviolet radiation that streams toward the Earth, day in and day out, from the burning surface of the Sun.
Ozone—a form of oxygen—is selective in what it takes from sunlight: In the early s, these concerns were validated by the discovery that the ozone layer in the stratosphere over Antarctica was thinning.
Overexposure to UV radiation in humans can cause a range of health and environmental effects, including skin damage skin cancers and premature agingeye damage including cataractsand suppression of the immune system. Scientific studies also suggest a link between ultraviolet radiation and adverse effects on some animal and plant life and some plastic materials.
Because of the risks posed by ozone depletion, leaders from many countries decided to craft a workable solution. Sincenations — almost every country in the world — have ratified a landmark environmental treaty, the Montreal Protocol on Substances that Deplete the Ozone Layer.
By agreeing to the terms of the Montreal Protocol, signatory nations — including the United States — committed to take actions to protect the ozone layer, hoping in the long-term to reverse the damage that had been done by the use of ozone depleting substances.
Scientists believe that ozone will return to its pre-CFC level by about Ways to Protect the Ozone Layer: Subsidize production of safer alternatives where possible. Establish controls to assure that new compounds to be used in high volume, are surveyed for effect on ozone.
Ensure technicians repairing your refrigerator or air conditioner recover and recycle the old CFCs so they are not released into the atmosphere. Vehicle air conditioning units should regularly be checked for leaks.
Replace halon fire extinguishers with alternatives e. Suggest school activities to increase awareness of the problem and to initiate local action. It includes the ban on ozone depleting chemicals most of them being CFCs.
There are various steps to control ozone depletion. These compounds are responsible for the depletion of ozone layer.

Ozone / ˈ oʊ z oʊ n /, or trioxygen, is an inorganic molecule with the chemical formula O ashio-midori.com is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O 2, breaking down in the lower atmosphere to O 2 or ashio-midori.com is formed from dioxygen by the action of ultraviolet light (UV) and electrical discharges.
