Population explosion, rapid industrialization, deforestation, unplanned urbanization, scientific and technological advancement, etc. The main causes of environmental pollution. About 35% of India's total area is seriously polluted. Three-quarters of the land is water, but there is a shortage of drinking water. In India, water sources are found in ponds and river lakes have been polluted and are unfit for consumption.
