What are the main problems related to the ozone?
Ozone, a molecule made up of three oxygen atoms, is related to two very different problems: the depletion of the ozone layer (stratospheric ozone) and the formation of ozone in the earth´s surface (ground-level ozone). • Depletion of the stratospheric ozone layer: 90% of ozone land is in the ozone layer. The ozone layer in the stratosphere is about 15-40 km on the earth’s surface. This layer has the duty to protect all forms of life from ultraviolet radiation coming from the sun (UV). In recent years part of this layer has been destroyed by the action of chemicals (CFCs and HCFCs), used for refrigeration and in some industrial uses, thus allowing a higher percentage of UV radiation to reach the earth’s surface. This type of radiation causes skin cancer, cataracts and other harmful effects on plants and animals, can also cause reductions in crop fields, disruptions in marine food chains, etc. Nowadays and thanks to efforts to prevent the use of CFCs, the ozone layer is beginning to reco
