Air Pollution

Air PollutionAir Pollution consists of gases, liquids, or solids present in the atmosphere
in high enough levels to harm humans, other organisms, or materials. Living at the
interface of Earth's surface and atmosphere, humans think of the atmosphere as
an unlimited resource, but we should reconsider because some of these
substances are harmful when they precipitate(form a solid) and settle on land and
surface waters.
One example of Air Pollution is Los Angeles which is the most polluted city
on the American Heart Associations Annual Air Pollution.

1. Analysis / Diagnosis: Outcome(s)• Air pollution harms health,
damages forest and lakes and lowers our quality of life.
• Air pollution caused by human activities can be carried hundreds of miles away making air pollution a global dilemma.
• Overall, human contribution of air pollution is the fact that much of the air pollution released by humans is concentrated in densely populated urban areas.
• Los Angeles, California, has air pollution in a form of a smog. It is the worst case of air pollution in the world due to its geography and heavily reliance on vehicles.
• More than 16 million people drive 9.5 million cars and trucks in Los Angeles and its suburbs.

2. Analysis / Diagnosis: Actions / CausesThe two main human sources of
primary air pollutants are:• Vehicle Exhaust• Tremendous Growth in
Industries
In L.A., air pollution is worsened due to its heavy vehicle traffic and weather conditions.
5
3. Analysis / Diagnosis: Beliefs
All these activities lead to the neglect of the environment:
• Industrial growth
• Economic Development
• Heavy reliance on Transportation
*Due to industrial growth and economical development they neglected to see that they depended more heavily on transportation.

4. Summary Issue
Summary
• The beliefs / values of most humans is that the atmosphere is
an unlimited resource.
• Smog conditions are worsened by heavy vehicle traffic, heat,
still winds.
• Unfortunate consequences are deadly diseases as asthma,
emphysema, lung and heart disease, and other respiratory
problems. Each year, millions of people die from these
diseases, which are directly related to poor air quality

5. Prescription / Proposal: Desired Beliefs
If Air Pollution persist, our health, family, and the environment will suffer tremendously as well as future inhabitants of the world from health problems.
"The bottom line is we've still got very dirty air and need very strong measures to achieve a future goal of clean air." (Feuer, G., N.Y. Times)

6. Prescription: Desired Actions / Behaviors• One way to control air
pollution is to find new sources of fuel that burn cleaner.
• Try to use public transportation and carpool!
• Reduce, reuse, recycle of products reduces all types of air pollution!
• Upgrade and maintain your vehicle.
• Another is to motivation through financial incentives and/or new regulations. Ex: Taxes
(What can I do to improve Air Quality?- article)
• Data
• Example
• Picture
Import, 3 or less examples, facts, pictures, graphs that emphasize / underscore the desired action.

7. Prescription: Desired / Planned Outcome
• More Clean Air Days
• Better health.
• Increased knowledge of Air Pollution.
• Better Environment for the future
• More Fuel efficient cars.

8. Summary Conclusions
In conclusion, Air pollution is a global dilemma. Each year, millions of
people die from these diseases, asthma, emphysema, lung and heart
disease, and other respiratory problems, which are directly related to
poor air quality. We can do little things every day to help reduce air
pollutants, and help better our air quality. Overall, we can provide a
better environment for future inhabitants of the world.
