Doing Our Bit for the Ozone Layer
We have all helped to thin the ozone layer, as we didnt know for a long time that the chemicals in some of our household products were destroying the ozone layer. Now that we have this knowledge, we can be part of the solution to protect the Earths fragile shield.
Most chemicals that destroy ozone have, or are being, phased out of use in most products. These include aerosols, refrigeration and air conditioning. However, household products bought before the international agreements were made may still be in use, such as fridges. These are expensive to replace and so should be cared for properly, to make sure that the CFCs they contain are never released into the air. Remember that a single CFC molecule can destroy 100,000 ozone molecules.
In addition, try to avoid buying any equipment that contains chemicals that damage the environment in other ways. Alternatives to CFCs include HCFCs, which are greenhouse gases, and contribute towards global warming.
