CHAPTER 3 UNIT 1: ENVIRONMANTAL POLLUTION
p. 43
Environmental Pollution is a term that refers to all the ways that human activity harms the natural environment.
Some pollution we can see
Some pollution we cannot see
The Earth’s Ecosystem, p. 43
Many people think of air, water and soil pollution as distinct forms of pollution. However, each part of an environment is dependent upon each other – air, water and soil.
The relationships among all the living and non-living things in an environment make up an ecological system called and ecosystem.
The Earth’s Ecosystem
An ecosystem includes all of the living things (plants, animals, and organisms) in a given area that interact with each other, as well as the non-living environments (weather, earth, sun, soil, climate, atmosphere) that surround the living things.
Eco = Greek (oikos = house); logy = study of…
Ecology
Ecology is the science that studies the biota (living things), the environment, and their interactions. It comes from the Greek oikos = house; logos = study. Ecology is the study of ecosystems. Ecosystems describe the web or network of relations among organisms at different scales of organization.
Air, Water and Soil Pollution, p. 43
How does air, water and soil pollution relate to and affect one another?
Air pollution
Water pollution
Soil pollution
POINT SOURCE AND NON-POINT SOURCE POLLUTION, p. 43
Point Source Pollution is when the pollution comes from one specific source
Nonpoint Source Pollution is when the pollution comes from many different sources or a large area
TYPES OF POLLUTION, pg. 43
The chief types of environmental pollution include:
Air Pollution
Water Pollution
Soil Pollution
Pollution caused by solid waste and hazardous waste
Noise Pollution
AIR POLLUTION, pg. 43
Air pollution is the contamination of the air by such substances as fuel exhaust and smoke. It can harm the health of plants and animals and damage buildings and other structures.
About 1/5 of the world’s people are exposed to hazardous levels of air pollution.

AIR POLLUTION, pg. 43
Our atmosphere consists of nitrogen, oxygen and small amounts of carbon dioxide and other gases and particulates (tiny particles of liquid and solid matter.)
Air pollution occurs when industries and vehicles release such large amounts of gas and particulates into the air that the natural processes can no longer keep the atmosphere in balance.
AIR POLLUTION, pg. 43-44
Outdoor air pollution
- What are some kinds of outdoor air pollution?
- What is smog?
- What is acid rain?
- What are fossil fuels?
- What is ozone?
- What is the Ozone Layer of the earth’s atmosphere?
AIR POLLUTION, pg. 44
- What are chlorofluorocarbons?
- Where do they come from?
- What do they damage?
- What is the Greenhouse Effect?
THE GREENHHOUSE EFFECT, pg. 44
AIR POLLUTION, pg. 43-44
- What are chlorofluorocarbons?
- Where do they come from?
- What do they damage?
- What is the Greenhouse Effect?
AIR POLLUTION, pg. 44
- What are “Greenhouse Gases”, where do they come from and how do they affect humans?
- What is Global Warming?
Indoor air pollution- What are some causes of indoor air pollution?
AIR POLLUTION, pg. 44
Indoor air pollution- What are some causes of indoor air pollution?
WATER POLLUTION, pg. 44
Water pollution is the contamination of water by sewage, toxic chemicals, metals, oils and other substances.
About 5 million people die every year from drinking polluted drinking water
- How is it in Cambodia? Do people drink or use polluted water? Give examples.
WATER POLLUTION, pg. 44
Water pollution occurs when people put so much waste into a water system that its natural cleansing processes cannot function properly.
Industrial acids
Farm pesticides and fertilizers
Animal manure
SOIL POLLUTION, pg. 44-45
Soil pollution is the destruction of the earth’s thin layer of healthy, productive soil where much of our food is grown.
FERTILIZERS
A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply one or more plant nutrients essential to the growth of plants. Many sources of fertilizer exist, both natural and industrially produced.
Fertilizers have good and bad results.
Synthetic fertilizers have influenced population growth.
FERTILIZERS
The development of synthetic fertilizer has significantly supported global population growth — it has been estimated that almost half the people on the Earth are currently fed as a result of synthetic nitrogen fertilizer use.
Without commercial fertilizers it is estimated that about one-third of the food produced now could not be produced.
SOLID WASTE
Solid waste is what we people throw away:
- Homes, offices, stores
- Paper, plastic, bottles, cans, Styrofoam, food scraps and yard trimmings
Open dumps damage natural beauty, stink and are breeding places for animals that carry diseases

HAZARDEOUS WASTE
Industrial waste is composed of discardedsubstances that can threaten human health and the environment.
NOISE POLLUTION
Noise pollution comes from such machines as airplanes, cars, trucks and motorcycles, construction machinery and industrial equipment…and in Cambodia….loud music.
Noise does not dirty the air or water, but it can causes discomfort and hearing loss in people and animals.
