On 19 December 1994 the General Assembly of the United Nations declared September 16 as International Day of Ozone Layer, commemorating the signing in 1987 of the Montreal Protocol on Substances that Deplete the ozone layer.
The 19 and 23 kilometers above the earth's surface in the stratosphere, a thin shield of gas, the ozone layer, surrounds and protects Earth from harmful sun rays. Whether we hear about the famous ozone layer, but we know little about it. The reality is that it works as a solar filter, letting the rays good, and not those that are harmful.
For years, all organisms that inhabit the planet have been accustomed to a certain level of ultraviolet radiation. The increase of this radiation creates problems of adaptation to this new environment. That is, not all organisms can live under these new conditions. Even the human being is affected, have increased cases of skin cancer, altered immune system eye problems.
is important to know the role of the ozone layer for life on Earth. We must be aware that this thin coat makes life possible on Earth.
emissions of chlorofluorocarbons, present in aerosols, solvents, coolants and industrial cleaning products are the main players, contributing 80% of ozone loss. Deforestation, the use of some fertilizers and the burning of fossil gasoline also produce substances that play a minor role in the destruction of the ozone layer.
Everyone can help preserve the ozone in our atmosphere. Information is the most important tool to take a responsible attitude towards the environment.
Change our habits and replace some of the daily application in our homes: to replace the use of plastic foam, sanitizers, solvents, and keep the good cars are some of the actions are a reflection of an education based environmental values \u200b\u200band principles.
