Environment : Ozone
layer depletion
By Faiznur Aslam Bin Azizzon (2PIC)

2.  The ozone layer is a layer in Earth's
atmosphere containing relatively high
concentrations of ozone
What is Ozone Layer?

3.  Although the concentration of the ozone in
the ozone layer is very small, it is vitally
important to life because it absorbs
biologically harmful ultraviolet (UV)
radiation coming from the sun.
Why it is important for Earth?

4.  When CFCs and HCFCs reach the
stratosphere, the ultraviolet radiation
from the sun causes them to break apart
and release chlorine atoms which react
with ozone, starting chemical cycles
of ozone destruction that deplete
the ozone layer. One chlorine atom can
break apart more than
100,000 ozone molecules.
Cause thinning of the ozone layer

5.  Stratospheric ozone filters out most of
the sun's potentially harmfulshortwave
ultraviolet (UV) radiation. If
this ozone becomes depleted, then more
UV rays will reach the earth. Exposure to
higher amounts of UV radiation could
have serious impacts on human beings,
animals and plants
Effects of ozone depletion

6.  1. Limit private vehicle driving
 2. Use eco-friendly household
cleaning products
 3. Avoid using pesticides
 4. Banning the use of dangerous
nitrous oxide
Measures to control ozone
depletion

7.  In conclusion, environmental problems
such as ozone depletion has already
stolen the various parties to seek a
solution. In fact, media outlets are not left
behind to cover and try to write articles to
create awareness against humanity in
order to maintain and preserve the
natural beauty.
