Environmental Degradation

Some of the key factors associated with environmental degradation are:

·        Population and Poverty

·        Urbanization and Industrialization

A complex relationship exists between population growth, environment and health. Increasing population leads to intensified human activities, which in turn lead to resource depletion and environmental damage.

In India population living in urban areas is growing day by day and due to absence of good public transport, the number of vehicles has increased exponentially, leading to deteriorating environmental condition. Due to limited resources and lack of infrastructure facilities, large percentage of urban population are forced to live in slums and shanty towns without basic amenities like safe drinking water, sanitation and sewage disposal.

Exposure to Chemicals

Industrialization is central to the development but in the absence of appropriate technology and environmental safeguards, industry becomes a major source of air and water pollution, hazardous chemicals and noise. A large variety of toxic chemicals such as dyes and co lour chemicals, pesticides, petrochemicals, metals etc. used in industrial operation can cause acute and chronic health effects in exposed workers and near by populations.

Environmental chemicals are also a matter of growing concern. Every year thousands of chemicals introduce in market and enter in various environmental media like air, water, food and soil. For example presence of arsenic and fluoride in water, persistent pesticides in food and heavy metals in air and soil are likely to cause toxicity in vulnerable groups like children and pregnant women.
