CFC’s should be banned around the world because it destroys our ozone layer and is dangerous to humans. This happens because the gasses that makes up CFC’s reacts with the gasses that makes up the ozone layer violently, causing explosions in the ozone layer, which destroys the ozone layer.

Impact as greenhouse gases CFCs were phased out via the Montreal Protocol due to their part in ozone depletion. However, the atmospheric impacts of CFCs are not limited to their role as ozone-depleting chemicals. According to NASA in 2018, the hole in the ozone layer has begun to recover as a result of CFC bans.

The reason for that policy is that CFCs escape into the stratosphere and destroy the ozone layer. Without that ozone as a shield, damaging ultraviolet light will reach the earth. There it will kill oceanic life, sicken green plants, and cause human skin cancer and blindness.

Answer. The use of Chlorofluorocarbons (CFCs) being discouraged because CFCs molecules were not settle in atmosphere and uv rays break these molecules which cause ozone depletion.

Inhaling CFCs The result is intoxication similar to that produced by alcohol, including lightheadedness, headaches, tremors and convulsions. Inhalation of CFCs can also disturb the heart rhythm, which can lead to death.

refrigerants

Chlorofluorocarbons (CFCs), including Freon, were used extensively as aerosol propellants. CFCs react with chlorine and break down, thereby destroying the ozone layer and allowing more radiation from the sun than is normal to reach the earth. Aerosol products have many uses, from hair care to cleaning and disinfecting.

Firstly, the ozone layer in the mid-latitude (e.g. over Australia) is thinned, leading to more UV radiation reaching the earth. Secondly, the ozone layer over the Antarctic, and to a lesser extent the Arctic, is dramatically thinned in spring, leading to an ‘ozone hole’.

In the Southern Hemisphere, the South Pole is part of avery large land mass (Antarctica) that is completely surrounded by ocean. This chlorine and bromine activation then leads to rapid ozone loss when sunlight returns to Antarctica in September and October of each year, which then results in the Antarctic ozone hole.

Antarctic

Scientists are optimistic that the hole may be starting to close; a 2018 assessment by the World Meteorological Organization found that the southern ozone hole has been shrinking by about 1% to 3% per decade since 2000—however, it likely won’t heal completely until at least 2050.

The ozone hole was first discovered in Halley Bay, Antarctica in 1981-1983 periods British Antarctic survey. Carbon monoxide has a greater affinity toward oxygen than carbon dioxide. Our atmosphere has 4 layers: troposphere, stratosphere, mesosphere and thermosphere.

The ozone layer over southern Canada has thinned by an average of about 7% since the 1980s. In the late 1990s, average ozone depletion in the summer over Canada was between 3% and 7%. Ozone depletion in Canada is usually greatest in the late winter and early spring. Large Antarctic ozone holes continue to occur.

Banerjee added that the ozone layer is expected to fully recover to 1980s levels by the 2030s in the Northern Hemisphere and by the 2050s in the Southern Hemisphere. The particular Antarctic hole in question is expected to recover by the 2060s.

Scientists are seeing signs that the 2020 ozone hole now seems to have reached its maximum extent. The Montreal Protocol bans emissions of ozone depleting chemicals. Since the ban on halocarbons, the ozone layer has slowly been recovering; the data clearly show a trend in decreasing area of the ozone hole.

Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV) radiation that reaches Earth’s surface, which increases the rate of skin cancer, eye cataracts, and genetic and immune system damage.

One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created. methyl bromideA compound consisting of carbon, hydrogen, and bromine.

Human activities cause ozone depletion and global warming Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below).
