    Ozone damage:

    We know that the ozone layer filters the harmful ultraviolet radiations and stop it from reaching the earth.

    Ultraviolet radiations can cause skin cancer, cataract and these radiations also weakens the immune system.

    Damage to the ozone layer is a cause for concern because the harmful ultraviolet (UV) radiation from the sun will reach the earth.

    This radiation is highly damaging to organisms, for example,​ is known to cause skin cancer in human beings.

    The steps that can be taken are:

    Limit the use of chlorofluorocarbons (CFCs)

    Try not to emit substances that can cause the depletion of the ozone layer.

    Use ozone friendly sprayers in perfumes, insect-repellants, etc.

    Answer:

    The ozone layer is a gaseous blanket that surrounds the Earth. The ozone layer serves as a protective shield for the planet's living creatures. The ozone layer's primary job is to block the Sun's dangerous ultra-violet rays.

    The ozone layer's depletion is a reason for concern because it will be unable to filter out ultra-violet radiation effectively, resulting in a variety of skin issues such as skin discoloration and skin cancer.

    The ozone layer keeps the planet's temperature constant. Damage to the layer could lead to the death of a large number of phytoplanktons, resulting in increased global warming.

    CFCs (chlorofluorocarbons) are chemicals that deplete the ozone layer. The release of CFCs into the atmosphere must be curtailed to limit the harm to the ozone layer. CFCs should be replaced with environmentally friendly replacements in refrigerants and fire extinguishers. In addition, the release of CFCs from industrial processes should be regulated.

    SOLUTION 1

    The damage to the ozone layer a cause for concern because:

    → It causes skin darkening, skin cancer, ageing, and corneal cataracts in human beings.

    → It can result in the death of many phytoplanktons that leads to increased global warming.

    To limit the damage to the ozone layer, the release of CFCs into the atmosphere must be reduced. CFCs used as refrigerants and in fire extinguishers should be replaced with environmentally-safe alternatives. Also, the release of CFCs through industrial activities should be controlled.

    SOLUTION 2

    Ozone layer is a protective shield around the earth. It prevents harmful ultraviolet radiation of the sun from reaching the earth. Air pollutants, like chlorofluorocarbons (CFCs), are causing depletion of ozone layer. This is allowing greater amount of UV radiation to reach the earth. UV radiation can (www.tiwariacademy.net) Class - 10 www.tiwariacademy.com A Free web support in education 4 upset the ecosystem by affecting photosynthesis in plants, destroying planktons and decomposers. In human beings, UV radiation may cause skin cancer, cataract of eyes and damage to immune system.

    Several developed as well as developing nations of the world have agreed to sign and obey the directions of TINEP (United Nations Environment Programme) to freeze the production of CFCs or to 1imit their production to some extent.
