How is ozone protected?
How can we protect the ozone layer? Avoid the consumption of gases dangerous to the ozone layer, due to their content or manufacturing process. Some of the most dangerous gases are CFCs (chlorofluorocarbons), halogenated hydrocarbon, methyl bromide and nitrous oxide. Minimize the use of cars.
Where can you protect the ozone layer?
Buy air-conditioning and refrigeration equipment that do not use HCFCs as refrigerant. Buy aerosol products that do not use HCFCs or CFCs as propellants. Conduct regular inspection and maintenance of air-conditioning and refrigeration appliances to prevent and minimize refrigerant leakage.
Why is ozone layer important?
The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet's surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects.
What is the role of ozone layer?
The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth's surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.
Where is the ozone hole?
The hole in the ozone layer — the portion of the stratosphere that protects our planet from the sun's ultraviolet rays — is continuing to decrease. The hole over Antarctica had an average area of 8.91 million square miles (23.2 million square kilometers).

Is the ozone layer healing 2022?
In early 2022, NOAA scientists found that concentrations of harmful chemicals had declined by just over 50 per cent in the mid-level of the stratosphere compared to the 1980s. Scientists at the NOAA say it is a “significant milestone” on the path to recovery.
Why should ozone layer be protected?
The ozone layer is a thin shield of gas in the Earth's atmosphere that protects the planet, absorbing the sun's ultraviolet (UV) rays and helping to preserve all life on the planet.
