2. INTRODUCTION
 The depletion of the ozone layer is a phenomena that
was observed during the later part of the 70s and has
since then showed a declining rate of 4% per decade
and there is a remarkable decrease over the polar
regions of the Earth.
 The main reason for the destruction of the ozone is by
man-made halocarbon refrigerants such as CFCs,
halons and freons that are released into the
atmosphere and are known as ‘ozone depleting
substances’ or ODS.
 Therefore many governments have banned products
that produce these ODS.

3.  The ozone layer is our warrior against the might Sun
that is bombarding earth with harmful UV radiation
and we are trying our best to protect it. Ozone is
basically a gas also referred to as O3 which is formed
and reformed constantly in our Earth’s atmosphere.
 It is also being said that the southern hemisphere of
the Earth could have an additional 20% depletion of
the ozone that could result in natural calamities like
tornadoes, avalanches, fires, tsunamis etc.

5. five ways to protecting the ozone
layer :
 Limit private vehicle driving
 Use eco-friendly household cleaning products
 Avoid using pesticides
 Developing stringent regulations for rocket
launches
 Banning the use of dangerous nitrous oxide

6. Limit private vehicle driving
 A very easy way to control ozone depletion would be to
limit or reduce the amount of driving as vehicular
emissions eventually result in smog which is a culprit
in the deterioration of the ozone layer
 Car pooling, taking public transport, walking, using a
bicycle would limit the usage of individual
transportation.
 It would be a great option to switch to cars/vehicles
that have a hybrid or electric zero-emission engine.

7. Use eco-friendly household
cleaning products
 Usage of eco-friendly and natural cleaning products
for household chores is a great way to prevent ozone
depletion. This is because many of these cleaning
agents contain toxic chemicals that interfere with the
ozone layer.
 A lot of supermarkets and health stores sell cleaning
products that are toxic-free and made out of natural
ingredients.

8. Avoid using pesticides
 Pesticides may be an easy solution for getting rid of
weed, but are harmful for the ozone layer.
 The best solution for this would be to try using natural
remedies, rather than heading out for pesticides.
 You can perhaps try to weed manually or mow your
garden consistently so as to avoid weed-growth.

9. Developing stringent regulations
for rocket launches
 The world is progressing in scientific discoveries by
leaps and bounds. A lot of rocket launches are
happening the world over without consideration of the
fact that it can damage the ozone layer if it is not
regulated soon
 A study shows that the harm caused by rocket
launches would outpace the harm caused due to CFCs.
 The global rocket launches do not contribute hugely to
ozone layer depletion, but over the course of time, due
to the advancement of the space industry, it will
become a major contributor to ozone depletion.

10.  All types of rocket engines result in combustion by
products that are ozone-destroying compounds that
are expelled directly in the middle and upper
stratosphere layer – near the ozone layer.

11. Banning the use of dangerous
nitrous oxide
 Due to the worldwide alarm caused by a study in the
late 70s about the alarming rate at which the ozone
was being depleted, nations around the globe got
together and formed the Montreal Protocol in the year
1989 with a strong aim to stop the usage of CFCs.
 . However, the protocol did not include nitrous oxide
which is the most fatal chemical that can destroy the
ozone layer and is still in use
 Governments across the world should take a strong
stand for banning the use of this harmful compound
to save the ozone layer.
