ozone depletion









































ozone depletion consists of 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. the latter phenomenon is referred to as the ozone hole. there are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events.
