2. Environmental pollution.
The ongoing development of the economy and the
population did increase pollution of land, water, air
and environment.

3. Causes of air pollution.
-Air pollution is caused by a wide variety of things. The earth is great at cleaning the air on its
own. However, air pollution has grown so much, the earth can no longer clean all of it.
This is starting to have adverse effects on the environment such as causing acid rain,
smog and a wide variety of health problems.
-Cars, trucks, jet airplanes and other combustion engine vehicles cause air pollution. The
exhaust from these contains carbon monoxide, nitrous oxide and gaseous oxide. This
type of air pollution creates smog (as seen in Los Angeles) which causes respiratory
health problems and holes in the ozone layer, which increases the exposure to the sun's
harmful rays.
-Factories, office buildings, homes and power-generating stations burn fossil fuels, which
cause air pollution. The burning of oil and coal (fossil fuels) also contributes to smog. This
air pollution destroys plants, damages buildings and creates oxidation on iron.
-Petroleum refineries release hydrocarbons and various particulates that pollute the air.

cities and
also in
rural
areas,

combustion engine vehicles cause air
pollution.

6. 4. Radiation Pollution: The WIPP Site
• Generally, one thinks in terms of a nuclear war when considering
pollution that involves radiation. There are many other sources of
radiation pollution. New Mexican's in 1988, for example, have been
expressing concern over the WIPP Site that will be used to store
low-level nuclear waste. Radioactive waste is especially troublesome
because some of it has to be secured for up to 250,000 years. This
period of time represents about one fourth of the entire time that
humans have been considered as a separate species Eitzen
(1986:99).
• Radioactive waste includes:
• used nuclear cores
• uranium tailings
• waste generated by hospitals, universities, and industrial plants.

8. • Solid Waste
Pollution
• As a result of waste
dumped in the
Atlantic Ocean,
"Swimming in the
Atlantic Ocean (on
the North-East coast
of the U.S.) is like
swimming in an
unflushed toilet"
(CNN report, 7-30-
88). Also See
(Eitzen, 2000:83-84)
for more on the
subject of solid
waste pollution.

9. - Pesticides
Pesticides used to kill indoor and outdoor pests, insecticides used to kill insects
and herbicides use to kill weeds all cause air pollution.
- Fertilizer Dust
Dust from fertilizers used to help plants grow causes air pollution.

10. • Deforestation

11. Water Pollution
1. industries (which pour a variety of nasty substances into lakes,
streams and the ocean)

12. • 2.Cities dispose
of their waste in
rivers (that often
serves as
drinking water).
• 3.There are also
oil and other
chemical spills.

13. • 4. Cities
dispose
of their
waste in
rivers
(that
often
serves
as
drinking
water).
