What is it?Antarctic ozone hole is ozone thinning or depletion The stratosphere over Antarctica every spring. This damage occurs due to the presence of chlorine and bromine in ozone-depleting substances in the stratosphere and specific meteorological conditions over Antarctica.

Is there a hole in the ozone layer in 2021?
