Adapting to a Changed Ozone Layer

Ozone layer depletion decreases our atmosphere’s natural protection from the sun’s harmful ultraviolet (UVHelpUVUltraviolet radiation is a portion of the electromagnetic spectrum with wavelengths shorter than visible light. The sun produces UV, which is commonly split into three bands: UVA, UVB, and UVC. UVA is not absorbed by ozone. UVB is mostly absorbed by ozone, although some reaches the Earth. UVC is completely absorbed by ozone and normal oxygen. NASA provides more information on their web site (http://www.nas.nasa.gov/About/Education/Ozone/radiation.html).) radiation. Increased exposure to UV radiation can have detrimental effects on human health and the environment.

Understanding these risks and taking sensible precautions will help you enjoy the sun while reducing your chances of sun-related health problems.
