The Disappearance of the Ozone Layer.: Possible Solutions to Ozone Layer Depletion

Laboratory studies have also shown that fluorine and iodine atoms participate in analogous catalytic cycles. Awareness has to increase if we can ever have the idea that we are going to control the depletion. This in turn also damages the ozone layer causing it to deteriorate. Scientists in 2014 observed a small increase in ozone—the first, they thought, in more than 20 years—which they attributed to worldwide with regarding the phaseout of ozone-depleting chemicals and to upper stratospheric cooling because of increased. Scientific consensus was established after regulation. Ozone at middle latitudes has declined, but by a much smaller extent a decrease of about 4—5 percent. Extra ultraviolet B radiation reaching Earth also inhibits the reproductive cycle of phytoplankton, single-celled organisms such as algae that make up the bottom rung of the food chain.

If it were not for the ozone layer, our Earth would be barren with slight traces of life. The ozone layer encircles the earth and occurs naturally. The , ratified in 1987, was the first of several international agreements enacted to halt the production and use of ozone-depleting chemicals. For more information on practices that can protect the ozone layer, read on! Archived from the original on April 3, 2009. It plays an important role in converting atmospheric carbon dioxide into oxygen.

These compounds are transported into the stratosphere by the winds after being emitted from the surface. Fahey, an atmospheric scientist at the , found that the drop in ozone would be from 1—2 percent if a fleet of 500 supersonic passenger aircraft were operated. Below is the detailed account of the chemicals responsible for the ozone layer depletion. The free chlorine molecule again reacts with ozone to form chlorine monoxide. The ultraviolet rays also damages to plants and plankton as well as cataracts.

Solution to Ozone depletion

Various studies have been undertaken to find out possible solutions. Some of the effects are mentioned below. Summing up By saving the ozone layer, we save this planet, and we save ourselves. This would require that the quantities of ozone to fall below 200 Dobson units, from the 250 recorded over central Siberia. This affects the ozone layer so severely that it contributes to 80% of the total ozone layer depletion. Another factor that may prolong ozone depletion is the drawdown of nitrogen oxides from above the stratosphere due to changing wind patterns.

The most common type of cancer is skin cancer. It can also directly affect the plant growth by altering the physiological and developmental processes of the plants. By limiting the burning of fossil fuels, we remove the gases that can interfere with ozone production, thereby encouraging the shield to replenish itself. The ozone layer is there to absorb the powerful radiations. More recently, policy experts have advocated for efforts to link ozone protection efforts to climate protection efforts. Most of the ozone that is destroyed is in the lower stratosphere, in contrast to the much smaller ozone depletion through homogeneous gas phase reactions, which occurs primarily in the upper stratosphere. The process of absorption of harmful radiation occurs when ozone molecules split up into a molecule of oxygen, and an oxygen atom.

Since about 1975, scientists have detected a severe drop in ozone concentration in the layer over the Antarctica each spring. More environment lessons What is Ozone Depletion? Ozone is a bluish-colored atmospheric gas which is formed when 3 oxygen atoms combine together through a chemical reaction. Ozone layer recovery The recognition of the dangers presented by and to the spawned an international effort to restrict the production and the use of and other. At the same meeting, MeBr , a fumigant used primarily in agricultural production, was added to the list of controlled substances. Presence of ozone in the lower atmosphere is considered as a pollutant and a greenhouse gas.

The exospherecomprises the second portion of the thermosphere that eventually merges into space. Buying and using recycled products, saving of energy, using of public transport can do a lot in combating ozone layer depletion. What is more, this is the number one reason why some amphibian species are on the verge of extinction. The Chlorine atoms react with the Ozone, setting out a chemical cycle that destroys the good ozone. It is found from 550 km to over 10,000 km above the surface of the Earth. The layer of ozone gas located in the stratosphere of our upper atmosphere protects the planet from severe ultraviolet radiations coming from the sun. Both types of ozone depletion were observed to increase as emissions of halocarbons increased.

The amount lost is more variable year-to-year in the than in the Antarctic. Such substances are found in vehicular emissions, by-products of industrial processes, aerosols and refrigerants. During the spring, however, the sun comes out, providing energy to drive photochemical reactions and melt the polar stratospheric clouds, releasing considerable ClO, which drives the hole mechanism. Aqueous cleaning, or even no-clean technology, are also alternative processes that can be used by the electronics industry. Continuing to update agreements such as the Montreal Protocol and the Vienna Convention can help the world continue to be on a path toward recovery. Ways to bring down ozone layer depletion Ozone layer depletion is not something that affects any specific country or region.
