The ozone layer is a layer of the Earth's atmosphere that absorbs most of the suns ultraviolet radiation (UV rays) and prevents these harmful rays from hitting the Earth's surface. These UV rays penetrate the Earth's surface, so without the ozone layer to block out most of the radiation, Earth would be a very dangerous planet to live on and...

The sun emits electromagnetic radiation at different wavelengths which is extremely dangerous. The ozone layer acts as a multilayer shield to protect against these harsh rays. The stratospheric layer of the ozone is the major protectant against the suns rays.

Chlorofluorocarbon (CFC) gases are commonly found in refrigerants, solvents, propellants, etc. In the 1980s the Montreal Protocol, an international commitment to cut down on the usage of CFC gases in hopes to reduce the damage to the ozone layer, was universally accepted by all countries that are a part of the United Nations (UN). Reducing the...
