The serious thinning of the stratospheric ozone layer is caused by anthropogenic emissions of ozone depleting substances, such(prenominal) as chlorofluorocarbons (CFC) and halons. The atmospheric concentrations of these compounds have increased during the stand firm several(prenominal) decades as a consequence of human activity (Ozone). The Ozone is demolish in the spring of the Antarctic by chlorine target during the sunless winter, due to the tilt of the earth. The chlorine is relieve oneselfed by a reaction between stable molecules that are determined on small clouds in the stratosphere, which can only appoint in the intense cold of winter. The stable molecules then get under ones skin the chlorine from CFCs that were broken up by the sunlight during... If you destiny to get a full essay, coiffure it on! our website: BestEssayCheap.com
