> ozone layer acts like an umbrella for the earth.
it is the upper atmosphere.
it protects humans n other organisms against ultraviolet radiation frm the earth.
certain man-made chemical like perfume deplete the ozone layer., leading to an increased level of UV radiation reaching the earth.
overexposure to UV radiations  can lead to many health problems.
 It causes not only sunburn but also greater incidences of skin cancer and eye cataracts.
