This document discusses the causes and effects of air pollution. It identifies two main sources of air pollution - natural causes like fires and eruptions, and human causes like emissions from factories, vehicle exhaust, and household products. The main human causes are identified as emissions from factories and chimneys, exhaust from vehicles, and various household and agricultural chemicals. The document states that all air pollution has two primary consequences - depletion of the ozone layer and risks to human and environmental health.
2. Air pollution is an occurrence, when the
air contains gases, dust or fumes in
harmful amounts. The substances that
cause air pollution are called pollutants.
3.
4. Air pollution is caused by many
pollutants, that are divided into 2 main
groups – the natural and human actions.
5. Natural actions, such as forest fires,
volcanic eruptions, wind erosion and
natural radioactivity, occur not very
often in comparison with human actions.
6. Therefore human actions are divided
again into few more parts, depending
on pollutant’s volume and extent:
7. High levels of gaseous chemicals, that
are not needed in the factories, are
emitted into the air up the long tubes,
called chimneys.
8.
9. Fumes from car exhaust contain
dangerous gases to people and other
living creatures, that breath them.
Additionally, they react with
environmental gases to create further
toxic gases.
10.
11. Crop dusting, fumigating homes,
household cleaning products, painting
supplies, the greenhouse effect and
insect killers (aerosols).
12.
13. All kinds of air pollution have 2 main
consequences – ozone diminution, and
risk and danger to humanity and health.
14. Driving: Save gasoline, Keep tires properly
inflated and aligned; Avoid waiting in long
drive-thru lines; When possible, use public
transportation, walk, or ride a bike.
At home: Conserve energy - turn off
appliances and lights when you leave the
room; Recycle paper, plastic, glass bottles,
cardboard, and aluminum cans; Plant
deciduous trees in locations around your
home to provide shade in the summer, but
to allow light in the winter.
15. “The flood of money that
gushes into politics today is a
pollution of democracy.”
– R. Buckminster Fuller.
