The ozone layer is a thin protective layer located in the stratosphere approximately 25-35 km from the Earth’s surface. Unlike the ‘bad’ ground-level ozone which produces smog, stratospheric ozone protects the environment and human health by filtering out damaging UV-B radiation which causes skin cancer, eye cataracts, weakening of the immune system, crop damage and inhibited plant and plankton growth. The substances that deplete the ozone layer are chlorofluorocarbons (CFCs), hydro chlorofluorocarbons (HCFCs), hydro bromofluorocarbons (HBFCs) and halons which are mainly used in the refrigeration, air-conditioning and fire extinguishing sectors. There are many and simple ways in which we can save our ozone layer. With these simple rules we can create a chain of consciousness that will make manufactures stop creating non-environmentally friendly products. Avoid buying and using aerosols and sprays composed of chlorofluorocarbon (CFC). •
Avoid using fire extinguishers with halogenated hydrocarbon since it is a very aggressive substance for the ozone layer. •
Avoid buying insulating material made up of CFC.
Maintain air-conditioning clean because if they do not function properly, they emit CFC to the atmosphere. •
Check the freezer and car air-conditioning. If they do not function properly, have them repair because they may have leaks. •
Opt to buy a refrigerator or an air-conditioning without CFC. •
Other Actions reduce Air Pollutions
Reduce the use of your car and of other gadgets like compressors, lawn mowers, etc. •
Use alternative means of transport: buses, bicycles, or simply walk. •
Reduce the use of heating and air-conditioning.
Buy energy saving gadgets and bulbs.
All of us can contribute to the protection of the environment. Before demanding politicians to implement policies to protect the ozone layer, let’s begin ourselves doing something for the environment
