Water, Air and Soil Contamination
Pollution is an environmental concern for people throughout the world. One university
study suggests that pollutants in the water, air, and soil cause up to 40% of the prema-
ture deaths in the world's population. The majority of these deaths occur in developing
countries.
Water in many developing countries is contaminated with toxic chemicals, also known
as toxins. The World Health Organization (WHO) estimates that 1.1 billion people
have little or no access to clean water. In many of these regions the water that is used
for drinking, cooking, and washing is the same water that is used for dumping sewage
and hazardous waste. Most developing countries cannot afford water treatment facili-
ties. Approximately 80% of infectious diseases in the world are caused contami-
nated water.
Air pollution is a growing problem throughout the world. Indoor air pollution is one of
the leading causes of lung cancer. Families in developing countries use open stoves
for cooking and heating their homes. These homes do not have proper ventilation. The
smoke, which is full of chemicals and carcinogens, gets trapped inside where families
eat and sleep. Outdoor pollution also causes disease and illness, especially in indus-
trial cities such as Beijing, China, where cancer is the leading cause of death. China re-
lies heavily on coal, which is considered the dirtiest source of energy. According to
the European Union, only 1% of urban dwellers in China breathe clean air on an aver-
age day. Neighbouring countries including Japan and Korea receive much of China's
pollution in the form of acid rain. This pollution results mainly from the coal powered
factories, which produce inexpensive goods for North American and European con-
sumers. Outdoor air pollution is also a concern in many wealthy countries. Those who
live and work in urban centres such as Los Angeles or Toronto experience many
warm days beneath a layer of smog.
Soil pollution is also a major concern, both in industrial and developing countries. Pol-
lutants such as metals and pesticides seep into the earth's soil and contaminate the
food supply. Soil pollution causes major health risks to entire ecosystems. This type
of pollution reduces the amount of land suitable for agricultural production and con-
tributes to global food shortages. Dumping of industrial and domestic waste products
produces much of the world's soil pollution, though natural disasters can also add to
the problem. In wealthy countries such as the US, protection agencies monitor the
food supply. The public is generally warned before major disease outbreaks occur.
Developing countries do not have this luxury. Farmers in poor nations grow food in
contaminated soil both to earn a living and to avoid starvation.

pected to increase worldwide. Today, the developed nations who achieved their
wealth at the expense of the environment will be held accountAs more people move
