[-1:39.00]When this became known,
[-1:40.00]many manufacturers stopped using CFCs in their aerosol cans.
[-1:41.00]They switched to other less harmful chemicals,
[-1:42.00]and labelled their cans 'ozone-friendly'or 'no CFCs'.
[-1:43.00]So when you next buy any type of spray can
[-1:44.00](such as a deodorant or insect spray),look for these labels.
[-1:45.00]The problem of refrigerators was more difficult to solve.
[-1:46.00]These machines could not be adapted as quickly as aerosol cans.
[-1:47.00]However,a German manufacturer,working with Greenpeace,
[-1:48.00]has now produced an ozone safe fridge.
[-1:49.00]It has been named the'Qreenfreeze' fridge and will soon be available.
[-1:50.00]Other manufacturers are rushing to produce similar models.
[-1:51.00]So the next time you or your parents go out to buy a fridge,
[-1:52.00]choose one of the ozone friendly models.
[-1:53.00]Then you will be doing something to help the environment.
