But a new study, surveying a part of the ozone layer that hadn't been examined before, shows that the overall problem hasn't improved in 20 years. If you add the tropospheric increases in, the total ozone density has only remained relatively constant. One is very short-lived substances (VSLS) that could be destroying portions of the ozone layer; research into that is ongoing. Restoration of the ozone layer is essential to reduce the harmful effects of solar UV radiation that impact human and ecosystem health. If we are to restore the ozone layer and reduce the harmful effects of ultraviolet radiation of life on planet Earth (including to humans), we have to figure out what's causing this odd behavior.
