Environment-current issues


Deforestation, Soil erosion, Overgrazing, Desertification, Air pollution from industrial effluents and vehicle emissions, Water pollution from raw sewage and runoff of agricultural pesticides, Tap water is not potable throughout the country, Huge and growing population is overstraining natural resources


India is a land of incredible diversity. The diversity of the Indian population is matched by the incredible physical diversity. The sixteen official languages of India, the five major religions, and the caste system create somewhat chaotic conditions for the nation. It dominates South Asian subcontinent; near important Indian Ocean trade routes.

Natural Vegetation


The Himalayan region, which is rich in vegetative life, possesses varieties that can be found practically from the tropical to tundra regions. Only the altitude influences the distribution of vegetation. In the rest of the country, the type of vegetation is largely determined by the amount of rainfall. Outside the Himalayan region, the country can be divided into three major vegetation regions: the tropical wet evergreen and semi-evergreen forests, the tropical deciduous forests, and the thorn forests and shrubs.


Vegetation of the Assam region in the east is luxuriant with evergreen forests, occasional thick clumps of bamboo and tall grasses. The Gangetic plain is largely under cultivation. The Deccan tableland supports vegetation from scrub to mixed deciduous forests. The Malabar region is rich in forest vegetation. The Andaman and Nicobar Islands have evergreen, mangrove, beach and diluvial forests. Much of the country's flora originated three million years ago and are unique to the sub-continent.
