Why should we preserve ozone layer?

Why should we preserve ozone layer?

The ozone layer is a natural layer of gas in the upper atmosphere that protects humans and other living things from harmful ultraviolet (UV) radiation from the sun. The ozone layer filters out most of the sun’s harmful UV radiation and is therefore crucial to life on Earth.

How can we protect the ozone layer Class 9?

Avoid Using ODS Reduce the use of ozone depleting substances. E.g. avoid the use of CFCs in refrigerators and air conditioners, replacing the halon based fire extinguishers, etc.

How is ozone harmful to us?

How is Ozone Harmful? When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.

How can we reduce CFCs?

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.

How ozone layer is formed?

Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The “ozone layer,” approximately 6 through 30 miles above the Earth’s surface, reduces the amount of harmful UV radiation reaching the Earth’s surface.

Can ozone kill you?

Whether in its pure form or mixed with other chemicals, ozone can be harmful to health. When inhaled, ozone can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and, throat irritation.

What is the main source of ozone?

How can we prevent ozone?

What You Can Do

  1. Stay indoors. Avoid spending too much time outdoors on high-level ozone days.
  2. Timing is everything. Gas up your vehicle in the early morning or late evening hours and mow your lawn later in the evening.
  3. Limit driving. Use public transit or carpool whenever possible.
  4. Conserve energy.

How can reduce ozone depletion?

To halt the depletion of the ozone layer, countries around the world agreed to stop using ozone-depleting substances. The main substances include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, carbon tetrachloride, methyl chloroform and methyl bromide.

Where is ozone found?

stratosphere
Most atmospheric ozone is concentrated in a layer in the stratosphere, about 9 to 18 miles (15 to 30 km) above the Earth’s surface (see the figure below). Ozone is a molecule that contains three oxygen atoms. At any given time, ozone molecules are constantly formed and destroyed in the stratosphere.
