Data available for urban air pollution: a case study of kanpur city in india

Answer 1

When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozonemolecules. ... ODS that release chlorine include chlorofluorocarbons. Since they are not destroyed in the lower atmosphere, CFCs drift into the upper atmosphere where, given suitable conditions, they break down ozone.

Answer 2

Answer:

Ozone Layer Protection. The stratospheric ozone layer is Earth's “sunscreen” – protecting living things from too much ultraviolet radiation from the sun. ... But through domestic and international action, the ozone layer is healing and should fully recover by about 2065.This natural sunscreen, known as Earth's ozone layer, absorbs and blocks the majority of the sun's UV radiation. Without this barrier in place, all of the radiation would reach Earth, damaging the DNA of plants and animals, like us humans. ... Within days of the ozone layer's disappearance, many plants would die.
