Ozone Layer

UV Rays
CFCs
Ozone Basics and Primary Topics for Consumers
The ozone layer is a concentration of ozone molecules in the stratosphere. About 90% of the planet's ozone is in the ozone layer. The layer of the Earth's atmosphere that surrounds us is called the troposphere. The stratosphere, the next higher layer, extends about 10-50 kilometers above the Earth's surface.
Stratospheric ozone is a naturally-occurring gas that filters the sun's ultraviolet (UV) radiation. A diminished ozone layer allows more radiation to reach the Earth's surface.
Overexposure to UV Rays
For people, overexposure to UV rays can lead to skin cancer, cataracts, and weakened immune systems. Increased UV can also lead to reduced crop yield and disruptions in the marine food chain. UV also has other harmful effects.
Whenever outdoors for lengthy periods, always apply sunscreen with proper Sun Protection Factor (SPF) rating, and be sure sunglasses you purchase provide 100% UVA and UVB protection.
