A multimedia Semi-timed presentation specially made for awareness for causes and effects of ozone depletion. Download recommended.

3. A gas composed of three atom of oxygen
Colourless gas that harmful to breathe
Nearly 90% Earth’s ozone is in the stratosphere
and is referred to as the ozone layer
This layer prevent the Ultraviolet radiation to the
earth by absorbing them
This layer has been facing a destruction in the
Antarctic region since the last 3 decade globally
termed as ‘OZONE HOLE’
'

4. REASONS FOR DEPLITION
CFC
9%
6%
5%
80%

5. CFC : The Dream Chemical
Very stable
Non-toxic
Inert in natural condition
Can used as refrigerants in refrigerators
and sprayers
Useful chemical reactant, so called
‘The Dream Chemical’

6. HOW CFC WORKS ON OZONE

7. Why in Antarctica?

8.  To humans and animals
 To plants
 To Eco-system
i. Blindness due to UV ray explosion
ii. Undesirable mutation (UV is a physical mutagen)
iii. Cataracts and other eye related disease
iv. Burning skin extreme bleeding
v. If any human remaining in the surface they would suffocate by
cancer like deadly diseases
i. UV-B generally reduce size, productivity and quality of plants
ii. Disturbance in photosynthesis
iii. Destruction of plant cell
i. Carbon concentration will shoot and a great decrease in
Oxygen concentration
ii. The ice in Antarctica will start to melt
iii. Total collapse in balance of ecosystem

1928 Thomas Midgley synthesizes
1930
Sydney Chapman describes theory that
explains existence of an ozone "layer"
1978
Total Ozone Mapping Spectrometer (TOMS) is
launched aboard NIMBUS-7 spacecraft giving
global coverage of ozone layer thickness

Deplete the Ozone Layer
1992-2002Maximum Ozone depletion observed
globally
2010 CFC production ends world-wide
TodayOzone healing
2030 Alternate of HCFC phased out
2040Production of all ODS ends
2055 Springtime Antarctic ozone hole
disappears
OZONE
“I HAVE A STORY FOR U”

10. MONTREAL PROTOCOL
Agreement established to protect the ozone layer
by reducing the production and consumption of
harmful substances in 1987. It entered into force
1989 and if all countries commit to its goal, the
ozone layer will be completely regenerate by 2055

11. What we have to do?
1. Limit private vehicle driving
2. Use eco-friendly household cleaning products
3. Avoid using pesticides
4. Developing stringent regulations for rocket launches
5. Banning of ODS substances worldwide

12. KEEP COOL..
Actually we don’t have to afraid in this problem now. Because our
MONTREAL PROTOCOL and other such OZONE PRESERVATION
works are healing the wounds of ozone .
That’s why UNITED NATIONS ENVIRONMENT
PROGRAMME (UNEP) made 2018 th theme as
“KEEP COOLAND CARRY ON”
