The document discusses air pollution and its effects. It begins by defining air pollution as gases, dust, fumes or odors in amounts that can harm humans, animals or damage plants. It then explains how increasing urbanization and industrialization have led to humans releasing more waste into the air than nature can handle. As a result, more pollution from industrial, commercial and domestic sources has been added to the air, especially in major cities. The document notes the adverse health effects of air pollution.

Air pollution occurs when the air contains
gases, dust, fumes or odour in harmful amounts. That
is, amounts which could be harmful to the health or
comfort of humans and animals or which could cause
damage to plants and materials.
•In the days before the proliferation of large cities
and industry, nature's own systems kept the air fairly
clean. Wind mixed and dispersed the gases, rain washed
the dust and other easily dissolved substances to the
ground and plants absorbed carbon dioxide and
replaced it with oxygen.
With increasing urbanisation and
industrialisation, humans started to release more
wastes into the atmosphere than nature could cope
with.
Since then, more pollution has been added to the air by
industrial, commercial and domestic sources. As these
sources are usually found in major cities, the gases
that are produced are usually concentrated in the
air around them. The adverse effects of air pollution
were graphically illustrated in London in 1952 when, in

7. SpeakingAir Pollution and Cardiovascular Disease
Air pollution is a heterogeneous, complex mixture of
gases, liquids, and particulate matter. Epidemiological
studies have demonstrated a consistent increased risk
for cardiovascular events in relation to both short-
and long-term exposure to present-day concentrations
of ambient particulate matter. Several plausible
mechanistic pathways have been described, including
enhanced coagulation/thrombosis, a propensity for
arrhythmias, acute arterial
vasoconstriction, systemic inflammatory
responses, and the chronic promotion of
atherosclerosis.
The purpose of this statement is to provide healthcare
professionals and regulatory agencies with a
comprehensive review of the literature on air
pollution and cardiovascular disease. In addition, the
implications of these findings in relation to public
health and regulatory policies are addressed.
Practical recommendations for healthcare providers
and their patients are outlined. In the final

Why Should Air Pollution?
Air pollution is a serious problem for our
existence in the world. it is very dangerous for human’s
health. It makes our cities uncomfortable. Air
pollution is one the cause of global waming. So, it can
be a big problem for all people in the world and the
next generation. It can damage the nature.
this matter is caused by people who don’t know about
the danger of air pollution. We need public awareness
to fight air pollution and keep our air clean. Another
problem is caused by car, motorcycle, and some public
transportations. They emit deadly gases. When they go
to somewhere, they spread air pollution. Besides, the
factory can cause air pollution. Many factories
create air pollution.
It is not going to be easy to solve this problem. We, as

AIR POLLUTION
Air pollution affects so much more than just the air we breathe.
Everything living has a need for clean, breathable air, from humans
and animals, to plants and trees. These needs make fighting air
pollution a major priority for everyone, to help heal and protect our
planet and future.
First, air pollution is a common issue among large cities, anywhere in
the world. High volumes of traffic, large industrial areas, and dense
concentrations of people all contribute to the amount of pollution in
the area. The effects of air pollution reach around the globe, wreak
havoc on people, plants, and animals. Changes to air and water
quality create dangerous and even deadly situations.
Secondly, breathing polluted air can cause damage to the heart and
lungs. Similar to the effects of smoking tobacco, inhaling the
particles in polluted air can cause people and animals to develop
heart and lung disease that could eventually prove fatal. Those with
certain medical conditions may find that high levels of air pollution
aggravate their symptoms. People with asthma, allergies, and
diseases resulting in breathing problems are usually the worst
affected.
In conclusion, we as citizens of the planet must take active steps to
curb air pollution by being conscious of our actions.
