OZONE LAYER DEPLETION
“A giant asteroid could hit the earth! Something else
could happen! The global temperature could rise!
Wakeup!”(edf.org)
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
The envelope of gas surrounding the Earth changes from
the ground up.”(Climate of Hope, p.p.25~63)
Now, the interesting fact is the information of a
layer of atmosphere, which surrounds our atmosphere.
“Orbiting above the Earth, an astronaut can look down
on our home and see the thin blue ribbon that rims our
planet. That transparent blanket in our atmosphere
makes life possible.” Yes, It is the Ozone Layer. It
provides the air we breathe and regulates our global
temperature. And it contains a special ingredient
called ozone that filters the solar radiation. Life as
we know it is possible in part because of the
protection afforded by the ozone layer.. The term
itself comes from the Greek word meaning “smell,” a
reference to ozones distinctively pungent odor. “Each
molecule contains three oxygen atoms bonded together
in the shape of a wide triangle. In the stratosphere,
new ozone molecules are constantly created in chemical
reactions fueled by power from the sun. The recipe for
making ozone starts off with oxygen molecules. When
struck by the suns rays, the molecule split apart
into single oxygen atoms, which are exceedingly
reactive. Within a fraction of a second, the atoms
bond with nearby oxygen molecules to form triatomic
molecules of ozone”(Climate Change).
“Ozone is an allotrope of Oxygen. Allotropes are two
or more forms of an element with different chemical
and physical properties. Molecules of diatomic oxygen,
the form of oxygen with which most the people are
familiar, contain two atoms each, as shown the formula
O2. In contrast, molecules of ozone contain three
atoms each and are represented by the formula
O3.”(Kelvin, page 46). Both oxygen produces ozone and
anthropogenic (human caused) sources. In the
troposphere the layer of atmosphere
