This video explains Ozone depletion in the Stratosphere, caused by the pollution of man-made compounds in addition to the lack of stratospheric ozone in Antarctica.
The phenomenon of ozone depletion and its links to possible hazard to life forms has captured international attention. India is a signatory to the Montreal Protocol, which sets the agenda for controlling ozone depletion by phasing out production and use of Chlorofluorocarbons.

http://mocomi.com/ presents: What is Ozone layer?
Life on earth is protected from the UV rays by a layer in the upper atmosphere (known as the stratosphere), which surrounds earth. This layer is called the Ozone layer.
Ozone is a gas made up of three oxygen atoms (O3) much like the layer of butter that settles on top if a glass of buttermilk is left unattended for a while.
This layer is just about 3-5mm thick. This thinly spread-out gas has been protecting life near the earth’s surface from the sun’s harmful UV rays for billions of years.
Ozone is spread thinly throughout the stratosphere in low quantities.
Watch this animated video to understand Why is the ozone layer in danger? and What is the ozone hole?

About the subject: Environment covers every living and non-living thing occurring naturally on Earth. Ecology is the scientific study of interactions between organisms and their environment. There are several practical applications of ecology in natural resource management, community health, economics, conservation biology and wetland management, among others. Biodiversity deals with different types of life found on earth. On Earth, biodiversity is not distributed evenly, rather it is the richest in the tropics. Studying Environment, Ecology and Bio-diversity is important for UPSC / IAS / IPS / IFS exam.

Think of the ozone layer as Earth's sunglasses, protecting life on the surface from the harmful glare of the sun's strongest ultraviolet rays, which can cause skin cancer and other maladies.
Ozone stinks. People who breathe it gag as their lungs burn. The EPA classifies ground-level ozone as air pollution.
Yet without it, life on Earth would be impossible.
A fragile layer of ozone 25 km above Earth's surface is all that stands between us and some of the harshest UV rays from the sun. The ozone molecule O3 blocks radiation which would otherwise burn skin and cause cancer. On Mars, which has no ozone layer to protect it, solar UV rays strafe the surface with deadly effect, leaving the apparently lifeless planet without the simplest of organic molecules in the upper millimeters of exposed Martian soil.
To keep track of our planet's ozone layer, NASA is about to launch the most sophisticated space-based ozone sensor ever: SAGE III, slated for installation on the International Space Station in 2014.
People were understandably alarmed, then, in the 1980s when scientists noticed that manmade chemicals in the atmosphere were destroying this layer. Governments quickly enacted an international treaty, called the Montreal Protocol, to ban ozone-destroying gases such as CFCs then found in aerosol cans and air conditioners.

No sunbathing without sunscreen - that was a mantra for sun worshippers back in the 1980s. The reason: The sun's dangerous UV-radiation passes through massive holes in the Earth's ozone layer and strikes the Earth surface - and our skins - nearly unhindered. Today, we are still busy drenching ourselves in suncream, but it's got quiet about ozone holes. Just what happened to them?

Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth's stratosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone over Earth's polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena, there are also springtime polar tropospheric ozone depletion events.
The details of polar ozone hole formation differ from that of mid-latitude thinning, but the most important process in both is catalytic destruction of ozone by atomic halogens. The main source of these halogen atoms in the stratosphere is photodissociation of man-made halocarbon refrigerants (CFCs, freons, halons). These compounds are transported into the stratosphere after being emitted at the surface. Both types of ozone depletion were observed to increase as emissions of halo-carbons increased.
CFCs and other contributory substances are referred to as ozone-depleting substances (ODS). Since the ozone layer prevents most harmful UVB wavelengths (280–315 nm) of ultraviolet light (UV light) from passing through the Earth's atmosphere, observed and projected decreases in ozone have generated worldwide concern leading to adoption of the Montreal Protocol that bans the production of CFCs, halons, and other ozone-depleting chemicals such as carbon tetrachloride and trichloroethane. It is suspected that a variety of biological consequences such as increases in skin cancer, cataracts, damage to plants, and reduction of plankton populations in the ocean's photic zone may result from the increased UV exposure due to ozone depletion.

NASA | Why is the Ozone Hole Getting Smaller?
For more information: http://www.nasa.gov/content/goddard/2014-antarctic-ozone-hole-holds-steady/#.VFvnQMdi-RI The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). The size of this year’s hole was 24.1 million square kilometers (9.3 million square miles) — an area roughly the size of North America. With the increased atmospheric chlorine levels present since the 1980s, the Antarctic ozone hole forms and expands during the Southern Hemisphere spring (August and September). The ozone layer helps shield life on Earth from potentially harmful ultraviolet radiation that can cause skin cancer and damage plants. The Montreal Protocol agreement beginning in 1987 regulated ozone deple... -
Ozone Layer & Hole - Video for Kids

Along-with beneficial rays from sun, there many harmful rays also which come from the sun.These harmful rays are known as ultraviolet rays ( uv rays) .If human skin is exposed too long to UV rays, it can cause cancer. But good news is that most of the harmful UV radiation is absorbed by a layer of ozone gas 20 -- 50 km above the Earth. But few human made chemicals are releasing few gases which are depleting the ozone layer.This video explains the whole ozone layer composition & depletion in an interesting way. -

Reducing ozone depletion
The Montreal Protocol is an international treaty designed to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. The phase out is planned via a timetable. For example, the substance hydro chlorofluorocarbon has a first deadline of 2015 and a final phase-out by 2030. In its daily work, UNIDO focuses on cost-effective ways to reduce ozone-depleting substances such as freons, halons and chlorofluorocarbons, in the areas of refrigeration, plastic foams, halons, solvents, fumigants and aerosol. Once the government of a developing country identifies a company that requires assistance in eliminating an ozone depleting substance that originates during the production cycle, it approaches UNIDO with a request to find a so... -

http://mocomi.com/ presents: What is Ozone layer?
Life on earth is protected from the UV rays by a layer in the upper atmosphere (known as the stratosphere), which surrounds earth. This layer is called the Ozone layer.
Ozone is a gas made up of three oxygen atoms (O3) much like the layer of butter that settles on top if a glass of buttermilk is left unattended for a while.
This layer is just about 3-5mm thick. This thinly spread-out gas has been protecting life near the earth’s surface from the sun’s harmful UV rays for billions of years.
Ozone is spread thinly throughout the stratosphere in low quantities.

Think of the ozone layer as Earth's sunglasses, protecting life on the surface from the harmful glare of the sun's strongest ultraviolet rays, which can cause skin cancer and other maladies.
Ozone stinks. People who breathe it gag as their lungs burn. The EPA classifies ground-level ozone as air pollution.
Yet without it, life on Earth would be impossible.
A fragile layer of ozone 25 km above Earth's surface is all that stands between us and some of the harshest UV rays from the sun. The ozone molecule O3 blocks radiation which would otherwise burn skin and cause cancer. On Mars, which has no ozone layer to protect it, solar UV rays strafe the surface with deadly effect, leaving the apparently lifeless planet without the simplest of organic molecules in the upper millimeters of exposed Martian soil.
To keep track of our planet's ozone layer, NASA is about to launch the most sophisticated space-based ozone sensor ever: SAGE III, slated for installation on the International Space Station in 2014.
People were understandably alarmed, then, in the 1980s when scientists noticed that manmade chemicals in the atmosphere were destroying this layer. Governments quickly enacted an international treaty, called the Montreal Protocol, to ban ozone-destroying gases such as CFCs then found in aerosol cans and air conditioners.

For more information:
http://www.nasa.gov/content/goddard/2014-antarctic-ozone-hole-holds-steady/#.VFvnQMdi-RI
The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). The size of this year’s hole was 24.1 million square kilometers (9.3 million square miles) — an area roughly the size of North America.
With the increased atmospheric chlorine levels present since the 1980s, the Antarctic ozone hole forms and expands during the Southern Hemisphere spring (August and September). The ozone layer helps shield life on Earth from potentially harmful ultraviolet radiation that can cause skin cancer and damage plants.
The Montreal Protocol agreement beginning in 1987 regulated ozone depleting substances, such as chlorine-containing chlorofluorocarbons and bromine-containing halons. The 2014 level of these substances over Antarctica has declined about 9 percent below the record maximum in 2000.
“Year-to-year weather variability significantly impacts Antarctica ozone because warmer stratospheric temperatures can reduce ozone depletion,” said Paul A. Newman, chief scientist for atmospheres at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
Scientists are working to determine if the ozone hole trend over the last decade is a result of temperature increases or chorine declines. An increase of stratospheric temperature over Antarctica would decrease the ozone hole’s area.

The Montreal Protocol is an international treaty designed to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. The phase out is planned via a timetable. For example, the substance hydro chlorofluorocarbon has a first deadline of 2015 and a final phase-out by 2030.
In its daily work, UNIDO focuses on cost-effective ways to reduce ozone-depleting substances such as freons, halons and chlorofluorocarbons, in the areas of refrigeration, plastic foams, halons, solvents, fumigants and aerosol.
Once the government of a developing country identifies a company that requires assistance in eliminating an ozone depleting substance that originates during the production cycle, it approaches UNIDO with a request to find a solution and introduce a more advance technological process in line with international standards.

Destruction of the Ozone Layer
The Ozone layer is a layer of the Earth's atmosphere which contains high concentration of ozone. Our planet will not be able to sustain life without it. Ozone Layer plays an important role in absorbing biologically harmful ultraviolet radiation emitted by the Sun. The majority of the atmosphere's ozone resides in the stratosphere, with the biggest concentration 20 to 25 km above Earth. The layer is being destroyed by man-made substances.
The substances are Chlorofluorocarbons, chemicals found mainly in refrigerants, solvents and propellants. CFC gases had damaged the ozone layer, creating a huge hole through which ultraviolet rays could penetrate.
During the 1970s, scientists discovered the chemicals known as CFCs, which can reach the stratosphere and destroy ozone. Frank Rowland and Mario found that CFC gases destroy ozone and showed the process.
The CFC gases rise up into the ozone layer, where ultraviolet light breaks the compounds apart and releases chlorine. A chlorine atom steals an oxygen atom from an ozone molecule (O3), creating oxygen gas and chlorine monoxide which effectively destroys the ozone molecule. A single chlorine atom can break from its oxygen atom and destroy 10,000 more ozone molecules. CFC's are very stable: they can last for decades in the atmosphere.
Effects:
•Higher chance of getting skin cancers and sunburns from UV rays
•Weakening of our immune system
•Loss of biodiversity in oceans, lakes and rivers
•Global Warming
