Answer:
Ozone is called the protective layer of the Earth because it block the ultraviolet rays from the sun.
In long
The ozone layer of the atmosphere protects life on earth by filtering out some of the harmful ultraviolet (UV) radiation from the sun. Thinning of this layer therefore poses a threat. In humans, it increases the risk of conditions such as skin cancer, suppression of the immune system and eye cataracts.
Thinning is a result of the release into the atmosphere of substances which destroy ozone. These include chlorinated compounds that are to be found for example in fridges, air conditioning systems and foam plastics.
Since 1987 there has been an international agreement called the Montreal Protocol, which requires signatory states to ban and restrict the use of ozone-depleting substances. The measures taken have been very successful. Thanks to the Montreal Protocol, emissions of these substances are now falling. So too, with certain exceptions, are levels of ozone-depleting gases in the atmosphere. Most current evidence suggests that the ozone layer is no longer thinning, and there are even signs that it is set to increase in thickness again.
