three reasons responsible for water scarcity in india
Water security The most common threat to water security is water scarcity. There can be several causes to water scarcity including low rainfall, climate change,[14] high population density, and overallocation of a water source. An example of periodic water scarcity in the United States is droughts in California. Another category of threats to water security is environmental threats.[15] These include contaminates such as biohazards (biological substances that can harm humans), climate change and natural disasters. Contaminants can enter a water source naturally through flooding. Contaminants can also be a problem if a population switches their water supply from surface water to groundwater. Natural disasters such as hurricanes, earthquakes, and wildfires can damage man-made structures such as dams and fill waterways with debris. Other threats to water security include terrorism and radiation due to a nuclear accident.[16]
Environmental issues in India Noise pollution or noise disturbance is the disturbing or excessive noise that may harm the activity or balance of human or animal life. Noise-wise India can be termed as the most polluted country in the world.[42] The source of most outdoor noise worldwide is mainly caused by machines and transportation systems, motor vehicles, aircraft, and trains.[1][2] In India the outdoor noise is also caused by loud music during festival seasons.Outdoor noise is summarized by the word environmental noise. Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential areas.
