Global Effects of Ozone Depletion Essay
Global Effects of Ozone Depletion
Ozone depletion in the earth's atmosphere is under constant scrutiny by the American press and people. Perhaps the concern is warranted; the ozone
layer protects life on earth by absorbing 97–99% of the damaging ultraviolet radiation from the sun (U.S. Environmental Protection Agency, 2006).
Over the past twenty years, the stratospheric ozone has decreased approximately 3% per decade. Possible concerns have been raised about loss of
polar caps, DNA damage, increased human health risks, and environmental process disturbance. Emerging research has helped clarify effects of global
ozone depletion. Three areas that have received recent scientific attention include UV effects upon macroalgae,...show more content...
al., 2004). However, approximately 90% of chloroform comes from natural sources. Therefore, if increased UV radiation has a similar effect on other
natural chloroform–emitting sources, the increase in organohalogens could be much more significant. If such an increase were significant, it would
create a vicious circle – increased UV radiation causes stress to living organisms; increased stress causes a higher production of organohalogens;
organohalogens breakdown stratospheric ozone; lower levels of ozone increase earth's surface radiation.
Increased surface radiation has also been linked indirectly to increased decomposition time. Barley that has been exposed to increased levels of UV–B
radiation has been shown to have increased levels of lignin (a binding agent) and cellulose (Pancotto, et. al., 2005). Microbes are unable to
breakdown lignin and cellulose as quickly as soluble carbohydrates. As a result, decomposition takes longer. Scientists speculated that barley litter
exposed to higher levels of UV radiation would decompose quicker than barley exposed to ambient levels of radiation (regardless of exposure to UV
radiation during growth). However, a group of American and Argentine scientists found the slight decrease in decomposition time to be insignificant
compared to the overall increase due to higher levels of cellulose and lignin. It is important to note, however, that the

Ozone Layer Depletion And Its Effects
Ian Grimmond
Ozone Layer Depletion When you walk outside, there is a pale blue molecule up in the Stratosphere that is protecting you every second of every
day of your life, this molecule is called ozone. Ozone is made of oxygen and has a chemical equation of OO2. It is layered all over our Stratosphere
and protects us from harmful UV rays from the sun. Without this in our atmosphere, we would mostly likely not live as long on this Earth. Sadly
however, this ozone layer is depleting, and has been for the past 45–50 years. Ozone depletion occurs when chemicals in aerosol cans called
chlorofluorocarbons (or CFCs) are released in the atmosphere. These chemicals break down ozone and make the layer of ozone we have become
thinner and thinner. Chemicals known as halogens: which includes, Iodine, Chlorine, Bromine, Astatine, and fluorine. The two halogens that are most
dangerous to the ozone layer are Bromine and Chlorine. This is because they are extremely potent and can destroy many molecules of ozone with a
single molecule. Singlehandedly one chlorine molecule can be responsible for the breaking down of over 100,000 ozone molecules. You may think
"This doesn't affect me, I can't be hurt by this slow progression." However, ozone is depleting is happening at an alarming rate. There are enormous
ozone layer holes in the atmosphere, mainly above the North and South Poles. Although it does not seem to pose a serious threat to people in the
mainland continents at

The Ozone Depletion
The earth atmosphere has many layers; the first two layers are the troposphere, the stratosphere, and the ozone layer which sits in the lower area of
the stratosphere. The troposphere layer is where a lot of human activity occurs, such as planes and mountain climbing. The next layer is the
stratosphere and this is where the ozone layer is located as well. The ozone layer helps protect people from ultraviolet radiation that mainly come
from the sun. The ozone layer can be different depending on the season and the location. Over the past few years, the ozone layer has been depleting
because of human activity. The main issue of the depletion of the ozone layer is the man–made products that have been created and has cause bad
effect on the ozone layer itself. The ozone is a gas in the atmosphere that protects all living things on Earth from damaging ultraviolet rays that come
from the sun. With the ozone layer depleting, it would be difficult for anything to survive much longer or not at all. The ozone acts as a shield to
protect living things from absorbing the ultraviolet ray and keeps them from being damaged. Many man–made materials are causing the ozone layer to
deplete at a faster rate. The author states, "Emissions of chlorine and bromine from CFCs and halons are to blame for excessive stratospheric ozone
depletion" (Ivanovich and Calm). This type of emission is going into the atmosphere and is breaking down the ozone layer. Consequently, this is
resulting in the

The Effects Of Ozone Depletion
The ozone depletion has been well documented to negatively affect planet Earth for years. The ozone is a thin layer of the EarthВґs atmosphere which
is responsible for absorbing the sun's harmful ultraviolet light ( What is Ozone Layer?,2017). The loss of ozone on earth will take a toll on human
health, plants and marine ecosystems, ultimately resulting in a planet that does not support living things. Today, this manifests in climate change. It is
easy for many to confuse these two issues, although they are connected in various ways. Loss of the ozone layer is caused by greenhouse gases such
as chlorofluorocarbons or CFCs (compounds with chlorine and/or fluorine attached to carbon), as well as , halons (similar compounds with bromine or
iodine) (Jain 2015). These chemicals can stay in the atmosphere for up to 100 years causing damage(What is Ozone Layer?,2017). Greenhouse gases,
like carbon dioxide, contribute to global warming, which then contributes to climate change by warming the surface and waters. These factors are
resulting in a domino effect on our environment. Climate change is classified as an abrupt increase in the Earth's temperatures typically caused by
human activity (National Aeronautics Space Administration 2016). Human activities that release pollutants in our atmosphere are changing it and
contributing to global warming and ozone depletion. With all the knowledge, resources and tools invented for the benefit of humans, one would think
that these

ISSUES AND CONCERNS ABOUT THE OZONE LAYER DEPLETION
INTRODUCTION
The ozone layer protects the Earth from the ultraviolet rays sent down by the sun. If the ozone layer is depleted by human action, the effects on the
planet could be catastrophic. In recent years, the ozone layer has been the subject of much discussion. And rightly so, because the ozone layer protects
both plant and animal life on the planet. The atmosphere is divided into five layers: the troposphere, the stratosphere, the mesosphere, the thermosphere,
and the exosphere. The troposphere is the layer closest to earth and is where all weather happenings occur. The stratosphere is located directly above
the troposphere, about 10–50 kilometers above the planet, and houses...show more content...
Although natural phenomena can cause temporary ozone loss, chlorine and bromine released from man–made compounds such as CFCs are now
accepted as the main cause of this depletion. The production and emission of CFCs, is by far the leading cause.
Human activity is by far the most prevalent and destructive source of ozone depletion, while threatening volcanic eruptions are less common. Human
activity, such as the release of various compounds containing chlorine or bromine, accounts for approximately 75 to 85 percent of ozone damage.
Perhaps the most evident and destructive molecule of this description is chloroflourocarbon (CFC). CFCs were first used to clean electronic circuit
boards, and as time progressed, were used in aerosols and coolants, such as refrigerators and air conditioners. When CFCs from these products are
released into the atmosphere, the destruction begins. As CFCs are emitted, the molecules float toward the ozone rich stratosphere. Then, when UV
radiation contacts the CFC molecule, this causes one chlorine atom to liberate. This free chlorine then reacts with an ozone (O3) molecule to form
chlorine monoxide (ClO) and a single oxygen molecule (O2). This threatening chlorine atom then continues the cycle and results in further destruction
of the ozone layer. Measures have been taken to reduce the amount of CFC emission, but since CFCs have a life span of 20–100

Most importantly it affects "microscopic photoplankton" which rest at the bottom of the food chain, placing us in extreme danger (Goldfarb
288). Henry Lee, leading researcher on ozone depletion for the
Environmental Protection Agency (EPA), says that UV rays will only have a slight effect on oceans, though. He says the problem lies on the fact that
70 percent of the Earth's surface is covered with water, making it a widespread problem.
In addition to that, humans exposed to excess UV rays over a period of time are likely to develop some form of cancer (Singer and Crandall npg).
The EPA released a report that stated if CFC's weren't controlled, in the future there will be approximately "40 million additional cases of
non–melanoma skin cancer found and 800,000 additional skin cancer deaths" (Singer and Crandall npg).
Now that scientists know what these and other "culprits" do, they're trying to find solutions to this world–wide problem. When they found
these chemicals to be harmful, environmentalists didn't hesitate in taking action.
They placed a boycott on the use of aerosol spray cans. The U.S. and Canada responded by banning "CFC powered spray cans," and that,
along with Europe agreeing to cut back by 35 percent, caused the rate of damage to fall drastically (Singer and Crandall npg). Therefore, manufacturers
have to stop using these. The only other

Ozone is a natural trace component of the atmosphere. It is created continuously through
the action of sunlight and oxygen in the upper atmosphere. At the same time this destroyed by
various reactions with other components in the air. The next result of these natural processes is the
so–called ozone layer in the stratosphere at altitudes between 15 and 50 kilometers in which the
concentration of the ozone is raised. Ozone is a colorless gas, a form of oxygen. However, an
ordinary molecule of oxygen contains two atoms. Because of ozone's composition, it is reactive. It

At first, the gas was little protection
from the sun's UV radiation. But according to some evolutionary theories, life forms on earth may
have been able to develop in water that filtered out most of the UV rays but allowed enough visible
lights for chemical reactions to take place.
However, ozone concentration are not static, winds transport, ozone throughout the

stratosphere. Although the photochemical process constantly produces ozone, it is also destroyed by
chemical reactions involving such gases as nitrogen, hydrogen, and chlorine. In addition, the
amounts of ozone change with seasons. The end results, is that over centuries
ozone in the stratosphere has maintained a dynamic equilibrium: the production and loss processes
have balanced. Keeping a layer of ozone around the planet that protects all life from too much UV
radiation. However, that delicate balance now may be threatened. Why did scientist become
concerned about the ozone layer? A number of events prompted scientific
research into the possibility that the ozone layer might be in danger. The research on the
stratospheric effects of shuttle launches altered others in the scientific community and in
government agencies to view chlorine compounds as possible threats to the ozone layer. Damage to
the ozone layer is largely caused by the release of certain volatile chemicals in the halogenated
hydrocarbons

Why is the ozone layer of much concern to scientists and environmentalists? The ozone layer is quite beneficial to human life and existence. The
destruction of this layer has been linked to the now common health conditions such as cancers, skin conditions and cataracts among others. It is
apparent that, without the ozone layer, all humanity would be lost to disease. Scientists all over the world have been widely researching to find out
ways in which the ozone layer is being destroyed through human actions. The ozone layer is gradually being destroyed by ozone depleting
chemicals. These chemicals include chlorofluorocarbons (CFCs), hydroflourocarbons (HFCs), methyl bromide, halons, methyl chloroform and
carbon tetrachloride among others (Ryding 173). These chemicals are used locally in coolants, fire extinguishers, solvents, pesticides, aerosol
propellants and foaming agents. These chemicals, once released, take quite a long time to degrade. It takes them years to move through the
atmosphere to the location of the ozone layer. These chemicals are broken down by the ultra violet rays from the sun ultimately breaking down into
chlorine and bromide molecules which are responsible for the destruction of the ozone layer. Ozone layer is found in two layers i.e. the "good" and
"bad" ozone layer (Filder 131). The bromide and chloride atoms destroy the "good" ozone. One molecule of chlorine is estimated to be capable of

The ozone layer is a very important component in the atmosphere. Ozone is not the same as the oxygen humans breathe. There is very little of this
gas in the atmosphere. First off, let's begin with a definition of the ozone layer. Ozone is a hot, slightly bluish gas. It is a molecule made up of three
oxygen atoms, which are very similar to the molecule we are familiar with (O2), the molecule needed for human respiration. Despite the major smog
problem, about 90 percent of Earth's ozone are actually in the stratosphere, a layer of the atmosphere far above the Earth's surface. It lies above the

If ozone did not act to filter a great deal of the ultra–violet radiation and if the rays were allowed to reach the surface of the Earth, then our planet
would be uninhabitable for life (Lutgens3). Ozone depletion and over–exposure to enhanced UV–B radiation can lead to deadly melanoma skin cancer,
increased eye cataracts, and damages to the near surface oceanic phytoplankton, which is the basis of the food chain. The natural depletion of the
stratospheric ozone chemistry cycle has been severely interrupted by ozone depletion associated with the decay of chlorofluorocarbons ("Links"4).
These are contained in a wide range of products, including aerosol sprays and refrigerants and insulating foam packaging.
Ozone concentrations are measured by a Dobson spectrophotometer and satellite–based instruments and results from these measurements show a
decrease in stratospheric ozone levels of about 1 percent per year since 1979. Studies show that every 1 percent decrease in ozone should produce a 2
percent increase in UV–B radiation, and a 4 percent increase in skin cancer (Thompson5).
Recently in the Arctic, the presence of significant CIO in the stratosphere has been established (Thompson 6). This shows the process of ozone
destruction in the Arctic. In this case, the ozone level in the Arctic also decreases. The frequency of this is not known. There may be a relationship
between large volcanic eruptions and even greater loss

as it protects us from the exposure of ultraviolet rays which leads to several harmful effects. Without the ozone layer, human will be more prone to
skin cancer and eye cataracts. Ultraviolet rays can also cause harm to marine life by reducing the amount of planktons and consequently depreciates the
amount of fishes in the ocean. Besides that, the depletion of the ozone layer disrupts the production of crops and forest growth, another two things

Air conditioners which use refrigerants such as R–410A and R–134A should be used instead as a replacement for those which use HCFCs to protect
the ozone layer from complete depletion (People's Daily Online, 2009). Besides that, Hong Kong has executed the Ozone Layer Protection
Ordinance in 1989 to ban the import of certain products and also to control the manufacturing of ozone depleting substances in the country. This
ordinance has also applied licensing restrictions to the imports and exports coming in and out of the country based on GovHK (2011). In
conclusion, the depletion of ozone layer can cause much harm and danger to the country and therefore, actions must be taken to stop this disaster
from happening. A comfortable life would most definitely be a preference but there are always alternatives to enjoy a better life without the usage of
ozone depletion chemicals. If the citizens of Hong Kong play by the rules, it would be a great start to a whole new generation where the usage of
hydro chlorofluorocarbons will be eliminated and the existence of the ozone layer can be prolonged.

Atmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful
ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists.
The ozone layer is a region of the stratosphere containing ozone, or O3 gas. The ozone layer is essential to both plant and animal life on earth because
it protects the surface from dangerous ultraviolet light.
However, industrial and domestic chemicals that are currently in use have been found to destroy ozone, and the problem has escalated to an ozone

The compounds most responsible for ozone layer destruction are CFC–11 (trichlorofluoromethane), CFCl3; CFC–12 (dichlorodifluoromethane),
CF2Cl2; and CFC–113 (1,1,2 trichlorotrifluoroethane), CF2ClCFCl2. All of these compounds are excellent refrigerants, and CFC–12 is marketed by
DuPont as Freonв„ў.3
The word "CFC" has become a generic term referring to any substance that is deleterious to the ozone layer. However, many destructive compounds are
not CFC's by definition. All ozone–destroying compounds contain at least one of two common elements: chlorine, or the more catalytic bromine.
Compared atom–to–atom, bromine can destroy 10–100 times the number of ozone molecules as chlorine. Fortunately, its atmospheric concentration is
much smaller.3
One of the other O3–destructive groups is called the hydrochlorofluorocarbons, or HCFC's. HCFC's are organic compounds in which not all of the
hydrogen atoms have been replaced by chlorine or fluorine. One such compound is R–22 (HCFC–22), CHClF2.3
Some other non–CFC compounds that destroy the ozone layer include carbon tetrachloride (tetrachloromethane), CCl4; methyl chloroform (1,1,1
trichloroethane), CH3CCl3; and methyl chloride (chloromethane), CH3Cl.3
The result of ozone layer depletion is a increase in ultraviolet rays at the surface. Humans, animals, marine life, and plants are all susceptible to UV

However, man–made CFCs are not water soluble. CFCs are free to rise all the way to the top of the stratosphere, where they break down, releasing
their chlorine radicals. The reaction is complex, involving many different chemicals, but the result of these reactions is that the CFC is recreated,
allowing it to continue wreaking havoc. Other processes are at work to remove CFCs from the ozone layer, so these reactions really can't continue
indefinitely, but scientists expect the CFC's already present to remain there for the next century. In fact, recent measurements show that the level of
CFCs is already declining, thanks to international treaties banning their production. (2) The banning of CFCs is a triumph of both science and
international diplomacy. In the early 80s, scientists working in the Antarctic noticed that there was a hole in the ozone layer over the South Pole.
Preliminary research pointed to CFCs as the culprit. In October 1987, the world's nations signed the Montreal Protocol, pledging to cut CFC production
in half over the next ten years. Subsequent scientific evidence suggested the threat was worse than realized, and the Protocol was strengthened twice –
once in London in 1990, and again in Copenhagen in 1992. The Copenhagen agreement moved up the complete ban of CFCs to January 1996. Today,
they are completely outlawed, although

The Effects of Ozone Depletion Essay
The ozone layer is a deep layer in the Earth's stratosphere that has an altitude of about 6.2 miles and contains a high concentration of ozone molecules.
The ozone layer shields the entire Earth from some of the harmful ultraviolet rays that come from the sun. The Earth's atmosphere is composed of
several layers, but the layer that we live in – the "troposphere" – is where most weather occurs. Above the troposphere is the stratosphere which is
where most of the effects caused by ozone holes and global warming originate. The ozone layer absorbs 97% to about 99% of the Sun's
medium–frequency ultraviolet light which could otherwise potentially harm and damage exposed life forms on the surface of the Earth. There are three

When chloroflurocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) reach the stratosphere, the Suns' ultraviolet radiation causes these
compounds to break apart and release chlorine atoms which then begin to react with the ozone. Just one chlorine atom in the ozone can break more
than 100,000 ozone molecules. Other chemicals that are harmful to the ozone include methyl bromide (which is used as pesticide), halons (which are
used in fire extinguishers), and methyl chloroform (used as a solvent in industrial processes). When methyl bromide and halons rise to the atmosphere
and break apart, they release bromine atoms. These bromine atoms are approximately 60 times more destructive to the ozone layer than chlorine atoms
are.
Dramatic loss of the ozone in the lower stratosphere was discovered over Antarctica in the 1970s. The severe depletion of stratospheric ozone in the
Antarctic has increased ultraviolet radiation at the surface and affected climate at southern high latitudes and northern low latitudes. Due to these
several ozone hole discoveries, an international treaty was signed in 1973 called the Montreal Protocol. The treaty was enacted to help reduce the

of ozone, and it acts like a sunshade for humans as it shields most of the harmful ultraviolet radiation that comes from the sun. The ultraviolet radiation
also takes part in forming the ozone initially as the reaction of radiation separating the oxygen molecule made up of two atoms results in the separated
oxygen molecules recombining with other oxygen molecules to form ozone. There are three types of Ultraviolet radiation and the three types differ in
wavelength. UV–A radiation, emitted at 315–400 nm is unaffected by ozone reduction and is not as harmful as UV–B radiation. UV–B radiation is
affected by the decrease in atmospheric ozone and it causes the most damage to living organisms on Earth and is emitted at 280–315 nm. The damage
from UV–B depends on the amount of atmospheric ozone present and cloud cover shielding the surface from some radiation, as well as the angle of
the sun in the sky. As stratospheric ozone diminishes, proportionately more of the shorter UV–B will reach the surface of Earth affecting many living
organisms. UV–C is lethal as it is emitted at 200–280 nm; however, it is completely absorbed by atmospheric ozone and oxygen. Therefore, even with
severe ozone depletion, UV–C radiation will not harm the surface of the Earth.
Ozone layer depletion is simply the reduction of the amount of ozone in the stratosphere. It has been determined that global stratospheric ozone levels
have declined to mean that the ozone layer is changing. The ozone has a large

Cause And Effects Of Ozone Depletion
Some scientists have proclaimed that the human race is slowly depleting the layer of ozone which protects us from ultra violet light. In reality,
humans have very little control of the world in which we live. Scientific evidence has shown that there is very little depletion in the ozone layer and
the contributions the human race makes towards this depletion is and always will be insignificant compared to nature. The theories of the depletion
and what it would cause are flawed and contradictory. Where and when did this global killing threat begin? It all began in the mid 1960's when the
United States government began pursuing super sonic transports. These would be planes which would travel in the stratosphere, very close to the
ozone layer. The first environmentalist complaints were actually of the noise factor. These large planes would be traveling in excess of the speed of
sound. Subsequently there would be sonic booms heard on the surface (Singer). The arguments fell on deaf ears in Washington. The next objection
came in the form of ozone depletion. A fleet of over 500 of these planes would ultimately destroy the ozone. This would allow more ultra violet
radiation to fall to the earth and in turn skin cancer rates would sky rocket. That was more than enough for the federal government to get involved, they
immediately canceled the project. At that time there was no study done to investigate these claims, but there has been since. The initial estimation was

CFCs are not easily broken down, once released; instead they are transported into the stratosphere where they are eventually broken down by UV
rays, releasing free the chlorine molecule. The chlorine becomes actively involved in the process of destruction of the ozone. "The net result is that
two molecules of ozone are replaced by three of oxygen, leaving the chlorine free to repeat the process thousands of times." Up to 80% of the current
damage already done to the atmosphere is due to the emission of CFC's from humans. Scientist's are also worried that continued global warming will
speed up ozone destruction and "increase stratospheric ozone depletion". Ozone depletion will intensify when the stratosphere becomes colder. Since
global warming traps heat in the troposphere, less heat will be able to reach the stratosphere which will make it colder. Greenhouse gases act like a
blanket for the troposphere and make the stratosphere colder. Global warming can make ozone depletion get much worse right when it is supposed
to begin its recovery during the next century. These problems will continue to get worse as more and more CFC's are released into the atmosphere.

Impact Of Pollution On Ozone Depletion
Jamie Kanzler Extended Essay: What is the impact of pollution on ozone depletion? Section 1: Introduction Air is classified as a mixture because it is
made up of many different elements. These elements include 78% nitrogen, 21% oxygen, 1% Argon, .4% water vapor, and .04% carbon dioxide.
Human activity has a very large effect on the air in our environment. Over time, humans have caused the once clean air to become polluted with
chemicals. These chemicals are called pollutants. A pollutant is defined as a substance created from human activity, that is present at a concentration
greater than its natural levels, and has a harmful effect on the environment. Many different pollutants exist in our air today and the concentration of
these chemicals causes their toxicity to vary. Generally, pollutants are classified into two groups: primary and secondary pollutants. A primary pollutant
