Over the course of time we have heard about all of the
detrimental effects that gases present to the depletion of the ozone layer. One
of the more common terms is known as chlorofluorocarbons, also known as CFC’s.
These gases have caused our ozone to deplete at rapid levels. Throughout the
years scientists have provided us with a substitute for CFC’s known as
hydrofluorocarbons, HFC’s. The substitute serves as cooling agents in our environments;
it does not contain chlorine nor does in deplete the stratospheric ozone layer.
Despite the advantages of this substitute it is still very detrimental to the perseverance
of our ozone layer due to its longevity within our atmosphere. One of the most
influential programs established to help us become more environmentally aware
is the Montreal Protocol. It has worked towards the reduction in emission of
gases and ozone killers and with its continuation scientists predict a drastic disappearance
in the dangerous gases.
Our society has been implementing programs towards a GREEN movement
in efforts to reduce the amounts of unfriendly gases depleting our ozone and
causing a rise in temperatures and destruction of habitats. We should all
challenge ourselves to become more environmentally aware in the continuance of
advocating for technology and scientific advances in helping to save our
environment.
