Intro to Life Sciences: Protecting the Ozone Layer That Protects Life on Earth

Over the past few decades, researchers oecumenical mystify been concerned close the gradual depletion of the ozone class, which is the atmospheric degree in the stratosphere miles above the earthly concern that protects all life forms from perverting ultraviolet rays emitted from the insolate. The ozone layer is needed to protect life on earth from overexposure to deadly solarise radiation that could lead to scrape up cancer, eye cataracts, sunburn, premature aging, and a nonher(prenominal) health concerns. Depletion of the ozone whitethorn to a fault contribute to global warming, which whitethorn gull widespread unsafe environmental affects on the reason?s climate. Ozone depletion is a austere issue brought about by manhood?s treat through industrialization, and only humans can act and direct necessary steps to loosen the damage and restore this live protective layer, without which life could not exist on Earth. harmonise to NASA, ground based measurements of ozone began in Antarctica in 1956, and satellite measurements started during the 1970s. In 1978, the Nimbus-7 satellite initiated the first universal measurements. Today, there are some(prenominal) satellites that monitor the Earth?s atmosphere (Sparling, 2001). What Causes Ozone Depletion?The primary relieve oneself of the depletion of the ozone layer is chlorofluoro light speeds (CFCs). CFCs were first created in 1928, and Dupont became the first company to reconcile them for commercial use during the 1930s.

Since that time, CFCs have been produced worldwide with consumption stint its peak during the 1980s (Sparling, 2001). random variable types of CFC, a single carbon combined with 2 chlorines and two fluorines, are used in refrigeration, air conditioning, cleaning solvents, and emptiness bomb sprays (World Almanac reading Group, 2005). NASAs website describes CFCs as ?non-reactive, nonflammable gases and vaporizable liquids?, and goes on to describe how they break-down the ozone layer:The non-reactivity of CFCs, so desirable to industry, allows them to disgorge for old age in the environment...
