Which of the following can be associated with ozone hole?
Ozone hole is aggravated due to modernisation and use of technology without environmental sustainability.
If ozone hole appears in tropical and temperate regions, it could cause a series of health problems.
Ozone hole is caused by increasing concentrations of ozone-depleting chemicals in the stratosphere that come from spray cans, refrigerants, air-conditioners (modern technology). These long-lived chlorofluorocarbons or CFCs (chemical compounds with chlorine and/or fluorine attached to carbon) remain in the atmosphere for decades to over a century depending on the CFC.
In the absence of ozone layer, there is a direct exposure to ultraviolet rays of the sun which can cause a variety of health-related issues such as cancer, mutations, etc.
