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 premature deaths among the world’s population.
Water in many third world countries is contaminated with toxic chemicals. The World Health Organization (WHO) estimates that 1.1 billion people have little or no access to clean water. Most developing countries cannot afford water treatment facilities. Apporximately 80% of infectious diseases in the world are caused by contaminated 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. The smoke gets trapped inside where families eat and sleep. Outdoor pollution also causes disease and illness, especially in industrial cities such as Beijing, Los Angles and Toronto.
Soil pollution is also a major concern. Pollutants such as detergents and pesticides go into the soil and contaminate the food supply. Dumping of industrial and domestic waste products produces much of the world’s soil pollution.
