A giant asteroid could hit the earth! Something else
could happen! The global temperature could rise!
Science is a body of knowledge containing various
streams such as physics, chemistry, biology etc. Its
sub-behavioral concept is Technology, which has made
tremendous changes in the modernized world. Climate is
a field of the science. Climate is a natural
consequence in which all the human beings
exist.(Technology and Environment page 25). The
first thing people see, in the morning, when they walk
outside is the sky or the colored sun. Is this world
giving us the privilege of seeing the natural colors
of the sun through all the layers of pollution within
the air?
A blanket of air, which we call the atmosphere,
surrounds the Earth. It reaches over 560 kilometers
(348 miles) from the surface of the Earth, so we are
only able to see what occurs fairly close to the
ground. Early attempts at studying the nature of the
atmosphere used clues from the weather, the beautiful
multi-colored sunsets and sunrises, and the twinkling
of stars. With the use of sensitive instruments from
space, we are able to get a better view of the
functioning of our atmosphere. The atmosphere, solar
energy, and our planets magnetic fields support life
on Earth. The atmosphere absorbs the energy from the
Sun, recycles water and other chemicals, and works
with the electrical and magnetic forces to provide a
moderate climate. The atmosphere also protects us from
high-energy radiation and the frigid vacuum of space.

The envelope of gas surrounding the Earth changes from
the ground up. Four distinct layers have been
identified using thermal characteristics (temperature
changes), chemical composition, movement, and density.

That comprises of Troposphere, Stratosphere,
Mesosphere and atmosphere. The atmosphere is
primarily composed of Nitrogen (N2, 78%), Oxygen (O2,
21%), and Argon (AR, 1%). Argon includes all the other
gases present in the atmosphere.A myriad of other very
influential components are also present which include
the water (H2O, 0 – 7%), “greenhouse” gases or Ozone

Ozone Layer Depletion

.. re available to man, than being mostly confined to polar water regions, another principal food resource could be added to man’s long list of them. Another important feature involved in a decline in phytoplankton numbers and productivity is the fact that phytoplankton helps produce and recycle the world’s oxygen supply ( Bowermaster et al, 1990, p.40 ). An increase in ultraviolet light can thus endanger an entire ecosystem without necessarily killing off the masses. By altering the respiratory balance in an ecosystem a variety of species would be affected.

Furthermore, the same oxygen recycled by phytoplankton is breathed by all animals and man himself thus adding to the importance of the threatened oceanic food chain. A weakened ozone umbrella could also have a tremendous impact on wildlife. Moreover, in support of devastating impact on the crops and animals, a diminished ozone layer has been associated with environmental damage and concern. The potential effect on the earth’s climate systems and weather is another negative aspect joined at the hip with a weakened ozone shield. The ozone layer is located in the stratosphere 15 – 50 km above the earth’s surface and plays a key role in the development of weather patterns ( Boisseau, 1987, p.7 ). When stratospheric ozone intercepts UV light, heat is generated. This heat helps create stratospheric winds, the driving force behind weather patterns ( Lemonick, 1992, p.42 ).

By changing the amount of ozone in the atmosphere, through man – made chemical interference, the regular wind patterns are affected. Ultimately, a diminished ozone layer will help heat up the atmosphere, adding to the threat of global warming ( Bowermaster, 1990, p.33 ). Convincingly, climatologists have noted that, Weather patterns have already begun to change over Antarctica ( Lemonick, 1992, p.42 ). Virtually all the CFCs and halons that have ever been released are still in the atmosphere ( Jones, 1992, p.39 ). This means that all the potent ozone destroyers which indirectly cause an increase in harmful ultraviolet light are still in the atmosphere accomplishing their chemically destructive tasks. Moreover, this destructive process will continue in the sky for the CFC’s and halon’s atmospheric lifetime of between 70 and 150 years ( Brune et al, 1992, p.38 ). The changing weather patterns and global warming will continue to exist as long as this ozone depletion is still occurring.

Ozone replenishes itself naturally but it will take the entire 21st century to return to pre – CFC levels ( Rowland, 1992, p.67 ). Ozone destruction has left an indelible mark on the atmosphere and will continue to do so for at least another century. The depletion of the ozone layer has a potential catastrophic effect towards the environment. Furthermore, a diminished ozone layer provides man with another of his already many viable health concerns. Man continually strives to better his health and tries desperately to stave off his self – acknowledged mortality. One of the many health concerns brought to light in wake of the ozone depletion story is cataracts. Cataracts is a medical condition in which the lens of the eye deteriorates causing blurriness and even blindness.

Statistics show that if the ozone layer is depleted by 1%, 100, 000 people worldwide would be blinded ( Brune et al, 1992, p.39 ). In addition to higher rates of cataracts, rates of skin cancer have also been linked to increased ultraviolet light in recent years. On a population wide – basis the connection between ultraviolet exposure and an increased risk of skin cancer have been established beyond question ( Cox, 1994, p.546 ). Admittedly, some of the recent increases in skin cancer rates can be attributed to the growth in popularity and fascination with tanning and sun bathing but another, and more convincing statistic states, In the 1930s, Canadians had one chance in 3500 of getting melanoma. In the 1990’s, the chance is one in 100.

( Brune et al, 1992, p.38 ) Most forms of skin cancer are not serious, but melanoma is fatal but in only 20 percent of the cases. ( Rowland, 1992, p.66 ) One doctor simplifies the matter by noting, Increased UV radiation has a negative effect on all biology. ( Boisseau, 1988, p.8 ) All biology having been pertained to all life without consequence to size, type, or location. Another negative effect of increased ultraviolet radiation is its link to immunological drawbacks. According to the World Resources Institute, A diminished ozone layer may also make people more vulnerable to a variety of infectious diseases like malaria ( Bowermaster et al, 1990, p.31 ).

Scientists agree that they already know that ultraviolet light can impair immunity to infectious diseases in animals ( Lemonick, 1992, p.41 ). Since it has been determined that immuno – effects have occurred in animals it cannot be preposterous to assume a similar effect can be set upon humanity which is genetically and historically, according to Darwinists, related to the animal kingdom. Immunological processes are carried out at the cellular level just as any other life processes supporting the notion that ultraviolet light carries enough energy to damage DNA and thus disrupt the working of the cells ( Lemonick, 1989, p.41 ). Furthermore, a U.N. research team stated increases in ultraviolet light speed up the onset of the AIDS virus ( Brune et al, 1992, p.32 ). Ultraviolet light reduces immune efficiency by suppressing the production of antibodies, helping cancers to be established and grow and increasing the susceptibility to herpes and leishmaniasis ( Lean et al, 1990, p.97 ). A suppressed immune system is just one more of many health concerns linked conclusively to a depleted ozone layer and the resultant UV increases.

The medical ramifications of increased UV light is another effect linked to the ecological ‘lit fuse’ we call ozone depletion. Ozone layer depletion possesses a potentially catastrophic cargo of harmful ultraviolet light concerning mankind and the planet Earth. Agriculture, wildlife, the environment and human health are all aspects of the planet Earth which are affected by a dramatic loss in atmospheric ozone stability. In the name of progress and societal advancement, mankind has released millions of tonnes of potent ozone destroyers in the last sixty years. The immediate scientific result of a depleted ozone layer is an increase in the amount of harmful ultraviolet light which reaches the Earth’s surface. Historically, mankind has endured atrocity, calamity, and ferocity.

In terms of the environment, it too has endured. Environmental endurance is tested regularly at the benefits of society. What makes man man is his ability to survive and repair the damage he has done. Al Gore defined man’s relationship with the sky in posing the frightening question, What will it do to our children’s outlook on life if we have to teach them to be afraid to look up? ( Lemonick, 1992, p.40 ). If the ozone layer can be freed from the clutches of chemical villainy, only then can it be truly said once again let there be light and not worry about the consequences Environmental Issues.
