OZONE LAYER DEPLETION António Gonçalves Henriques 1 António Gonçalves Henriques 1 OZONE LAYER PROTECTION António Gonçalves Henriques 2 • The ozone layer or ozone shield refers to a region of Earth’s stratosphere that absorbs most of the Sun’s ultraviolet (UV) radiation. It contains high concentrations of ozone (O 3) relative to other parts of the atmosphere, although still very small
(2) Why it concerns you? The ozone molecules form a protective layer which extends from about 16 km to 50 km up above the earth at low latitudes, and from about 8 km to 50 km at high latitudes.
The stratospheric ozone layer absorbs most of the harmful ultraviolet B (UVB) radiation (shortwave UV rays measuring 280-315 nanometers, or nm) emitted by the sun. In small amounts, UVB radiation is helpful to life (e.g., for the production of vitamin D ).
We care about ozone depletion because a thinner ozone layer allows more UV radiation to reach the Earth’s surface. Overexposure to UV radiation can
Prevention for Global Warming. Global warming refers to the Earth’s air and oceans gradually heating up to a point that disrupts balance, a problem that is continually getting worse.

The United Nations General Assembly has designated September 16 as the International Day of Prevention of Ozone Layer. Sources of Ozone Layer Ozone in the Earth’s stratosphere is created when UV Light strikes ordinary Oxygen Molecules (O 2 ) contains two atoms of Oxygen.
The unit also covers assessing the impact of ozone layer depletion and global warming on fire protection industry work practices and proposing changes to work practices in the fire protection industry to tackle the threat of ozone layer depletion and global warming.
Recent data suggest that further ozone depletion is occurring from plumes of water vapour entering the atmosphere as a result of summer storms induced by climate change.6 Last year, ozone depletion was even detected in the northern hemisphere. Because of the long atmospheric lifetime of CFCs, the ozone layer will not recover until at least 2060. Since the impact of increased UVB exposure on
