Q:

How can you protect the ozone layer?

A:

Some of the ways to help protect and stop the depletion of the ozone layer include not buying products in aerosol cans, maintaining air-conditioning filters and units, using mass public transit or riding a bike instead of driving, and purchasing energy saving light bulbs and appliances. The ozone layer protects the earth from the suns harmful ultraviolet rays.

Over time, the ozone layer has begun depleting due to man-made chemicals and emissions from vehicles and large appliances. Because of the damage to this extremely important atmospheric shield, Congress passed the Clean Air Act in 1990. The Clean Air Act required companies to stop producing products that damaged the ozone layer. One of these products is chlorofluorocarbons, or CFCs. These were used in a variety of products and caused significant damage to the ozone layer.

Even though the Clean Air Act regulates the use of chemicals that are harmful to the ozone layer, damage still occurs because of modern products. The ozone layer is expected to continue to deplete over the next few years. After the damage is controlled and the depletion stops, it is still likely to take around 60 years for the ozone layer to heal and build back up to its original state.

  • Q:

    How can people prevent ozone depletion?

    A:

    Individuals can prevent ozone depletion by not using products that contain chlorofluorocarbons, or CFCs, hydrofluorocarbons, or HCFCs, and other human-made substances that destroy ozone molecules. Additionally, governments can ban the use of such substances and enforce regulations concerning the safe disposal of equipment that contains them.

  • Q:

    What are the effects of pollution on the ozone layer?

    A:

    One of the greatest and most dangerous effects of pollution on the ozone layer is that it creates holes in the atmosphere, which allow powerful ultraviolet rays from the sun to reach the Earth’s surface. Many varieties of atmospheric pollutants — toxic chemicals, synthetic substances, such as DDT, and manmade chemicals — enter the atmosphere. They may remain intact and linger for decades, even up to a century, which gives them time to create considerable damage to the atmosphere.
