The Hole in the Ozone Layer

Since existing of humanity they tried to make their life much easier, happier, so they invented cars, air-conditioners, fire extinguishers and many others. As a result the ozone layer destroy . Ozone itself is a useful protective layer high above our heads. Scientific evidence indicates that the damage of the ozone in the stratosphere high above the planet’s surface deplete as the result of the widespread use of chemicals. The stratospheric ozone consider by manufactured chemicals, containing chlorine and/or bromine. These chemicals use «ozone-depleting substances» (ODS) which under normal conditions are chemically harmless. Stratosphere is about 15-50 kilometers above the Earth surface. What’s more, ODS have a long lifetime in our atmosphere - up to several centuries. This means most of the O D S emit over the last 80 years and they are still making their way to the stratosphere, where they will add to the ozone destruction. For example, large amounts of gas called C FC s produce in the twentieth century for use in everyday appliances like fridges, aerosol spray cans, and fire extinguishers. One type of ODS is Halons. They release in specialized fire extinguishers. Halons can destroy up to 10 times as much ozone as CFCs can. For this reason, halons call to be the most serious ozone-depleting group of chemicals. Ozone layer holds harmful ultraviolet radiation which bring by the Sun ultraviolet radiation. It can damage cells of living, affect the growth of plants. The worst is the generation of “greenhouse”, or “global warming”.
