Smog, Sustainable future

1. Smog

2. Smog originally named for the mixture of smoke and fog in the air..
 Classic smog results from large amounts of coal burning in an area and is caused
by a mixture of smoke and sulfur dioxide.
 Smog is a problem in a number of cities and continues to harm human health.
 Ground-level ozone, sulfur dioxide, nitrogen dioxide carbon monoxide are
especially harmful for senior citizens, children, and people with heart and lung
conditions such as emphysema, bronchitis, and asthma.
 Effects: It can inflame breathing passages, decreasing the lungs' working capacity,
and causing shortness of breath, pain when inhaling deeply, wheezing, and
coughing. It can cause eye and nose irritation and it dries out the protective
membranes of the nose and throat and interferes with the body's ability to fight
infection, increasing susceptibility to illness.
 Hospital admissions and respiratory deaths often increase during periods when
ozone levels are high.

3. Photochemical Smog
 In the 1950s a new type of smog, known as Photochemical Smog, was first
described
 haze in the atmosphere accompanied by high levels of ozone and nitrogen
oxides, caused by the action of sunlight on pollutants.

5. Thermal Inversion

6. When the air layer pattern is reversed, then the
phenomenon called temperature inversion occurs.
Temperature inversions last only a few hours, but there have
been cases where they remain for several days.

7. Sustainable Future
Evaluating the possibility

8. Montreal Protocol
 The Montreal Protocol on Substances that Deplete the
Ozone Layer was designed to reduce the production and
consumption of ozone depleting substances in order to
reduce their abundance in the atmosphere, and thereby
protect the earth’s fragile ozone Layer. The original
Montreal Protocol was agreed on 16 September 1987
and entered into force on 1 January 1989.
 On a cold day in September 1987 in Montreal, 24
countries signed the Montreal Protocol on Substances
that Deplete the Ozone Layer. The document itself was
rather short – only about eight pages – but the impact
that it had on the world community was significant. The
Protocol that was signed on that day, 20 years ago, had a
number of key elements, all of which have contributed to
the success that has been achieved by the Protocol to
date.

9. Success
 In addition, in 2003, recognition of the Protocol from the political
side came in the statement of United Nations Secretary General Kofi
Annan, that “perhaps the single most successful international
environmental agreement to date has been the Montreal Protocol, in
which States accepted the need to phase out the use of ozone-
depleting substances.” Finally, the Montreal Protocol is recognized
in the United Nations 2006 report on the Millennium Development
Goals, under Goal 7, as a global success story for its work in
catalysing global action to help us reduce the amount of chemicals
damaging the ozone layer.

10. Sustainable future!
Is possible….
 International cooperation to cut
Carbon emissions.
 Monitoring and Enforcement of
plan- Role of government and
authorities
 Industries behavior and
cooperation.
 Individual’s responsibility!

11. Individual’s role
List down what
you can do?

13. Your task: Inquire further on these view and write
note in favor or against climate change.
