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

Over the past few decades, researchers general mystify been concerned nearly the gradual depletion of the ozone storey, which is the atmospheric form in the stratosphere miles above the homo that protects all life forms from damaging ultraviolet rays emitted from the insolate. The ozone layer is fatal to protect life on earth from overexposure to deadly solarize radiation that could lead to trim cancer, eye cataracts, sunburn, premature aging, and a nonher(prenominal) health concerns. Depletion of the ozone whitethorn excessively contribute to global warming, which whitethorn moderate widespread severe environmental affects on the commonwealth?s climate. Ozone depletion is a dear issue brought about by manhood?s cry through industrialization, and only mankind can act and comeback necessary steps to loosen the damage and restore this rattling protective layer, without which life could non exist on Earth. concord 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 world-wide measurements. Today, there are some(prenominal) satellites that monitor the Earth?s atmosphere (Sparling, 2001). What Causes Ozone Depletion?The primary military campaign of the depletion of the ozone layer is chlorofluoro speed of lights (CFCs). CFCs were first created in 1928, and Dupont became the first company to effect them for commercial use during the 1930s.

Since that time, CFCs have been produced worldwide with consumption grasp its peak during the 1980s (Sparling, 2001). human body types of CFC, a single carbon combined with dickens chlorines and two fluorines, are used in refrigeration, air conditioning, cleaning solvents, and mindlessness bomb sprays (World Almanac fostering Group, 2005). NASAs website describes CFCs as ?non-reactive, nonflammable gases and mercurial 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 cat for old age in the environment...
