Question

effects of air pollution :ozone depletion

Answer 1

effect of air pollution ozone depletion Ozone depletion describes two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions.[1] The latter phenomenon is referred to as the ozone hole. There are also springtime polartropospheric ozone depletion events in addition to these stratospheric events.
