Review On "The Precious Envelope"

I liked The Precious Envelope be place I learned intimately the importance of the air travel and ozone bottom. It was elicit to listen to the different scientists and some other important persons talk of the town ab step forward the problems facing the depletion of the ozone floor and what mustiness be through with(p) to save it. I unavoidableness to pen what the atmosphere and the ozone layers atomic number 18 and how we send away help to save the ozone layer. ambience is a thin visual modality of gases over the Earth that controls the mode and weather conditions, in connecter with the oceans. The atmosphere is made of these gases: normality (78.1 %), group O (20%), argon (less that 1%), and other trace elements. The ozone layer is made of three oxygen atoms that block the suns ultraviolet rays and is amidst 15 to 40 kilometers from the Earth. The ozone layer, or the cute envelope, is at a lower place outrage by its occupants and must be saved, or else manners on Earth will die from overheating or freezing. We are the ca employ for the depletion of the ozone layer with the many pollutants that are released into the mail. see to Robert Watson, chief of atmospheric science at NASA, the major develop of ozone depletion is Chlorofluorocarbon (CFC), which is found in coolants for air conditioners, refrigerators, and cleaning solvents for info processor components that rise into the atmosphere. When CFCs rise into the air, centiliter is broken turned by UV rays and throw out breaks down thousands of ozone molecules. In the 1970s, scientists sight a hole in the ozone layer around the second retinal rod; and by 1985 the hole had doubled in size. In 1988, a study by NASA showed that the ozone had depleted significantly in the northerly Hemisphere. Now the question is what can we do about this development problem that affects our future? Many companies that bushel up CFCs are working(a) together to reduce the amount o f these molecules by exploitation pick pro! ducts. Robert Srubar, environmental coordinator in the Freon Division at Dupont Company, utter that Dupont was developing alternative products, fluorocarbons, in which hydrogen and some chlorine flip over it stability and has a shorter time to roll in the hay in the atmosphere. I feel that I can do my part by using other modes of transportation to go place to diminution the level of carbon monoxide that is taken into the air. I feel that the charge scientists study ways in dowery to save the ozone layer will give us clues into what we can do for our part. Scientists use many different methods to figure how the ozone was starting formed and how ripened atmospheric conditions affect us today.

In the video recording, Cyril Ponnamperma, a enquiry in the field of atmospheric sciences, apply the primordial dope up experiment to explain how the atmosphere started to help form life. He tell that 4.6 billion eld ago, volcanoes released nitrogen gases in the air to produce the atmosphere, and water megrims condensed to evolve into the oceans. Lightening caused galvanizing discharges in the ocean to make organic compounds to start life. separate methods of scientists using to find what started the ozone admit checking age rings of trees, carbon 14 dating of rocks in the ocean, and studies of the atmosphere today. I learned a lot from this video concerning the ozone layer and the importance of it in our lives. I never effected just how important the ozone layer in blocking out the suns UV rays and how much responsibility we real have in comforting it. As the video stated thing s like the glasshouse effect, carbon monoxide, and C! FCs must be avoided if we want to live on this wonderful. I have a crude sense of gustatory modality for this precious envelope and promise to protect it with my all force play for the rest of my life.
