Will the Ozone Layer Recover? Can We Make More Ozone? The answers are: yes, assuming full compliance with the Montreal Protocol, and no.
It makes sense to explore the questions in reverse order, but understanding either answer requires some basic facts about how ozone levels remain relatively constant and what ozone depletion means. In this discussion, we are mainly concerned with global ozone depletion, as opposed to what happens during the annual Antarctic ozone hole Ozone molecules are constantly being produced and destroyed by different types of ultraviolet light from the sun. Normally, the production and destruction balances, so the amount of ozone at any given time is pretty stable. Www.stateoftheair.org/2011/health-risks/health-risks-particle.html.
Ever look at dirty truck exhaust? The dirty, smoky part of that stream of exhaust is made of particle pollution. Overwhelming evidence shows that particle pollution—like that coming from that exhaust smoke—can kill. 150,000 mg in scientici notation.
