ஆம ம  த ர . You are absolutely right. Not only food is a slow pisoon, water is also a slow pisoon. Because of industrialization, wastewater from industries is discharged into rivers and lakes in India. The good example is River Ganges which has been polluted by tannery wastewater. Since India is a developing country, it invests/targets on infrastructure establishment, improving educational system and installation of new industries to compete with China. Therefore, India doesn\'t pay more attention on pollution prevention principles. China has just started to realize its environmental problems and making decisions to protect environment. Instead, developing countries are spending more money to remove the pollutants in water with some cheaper and greener technologies. Our politicians are not good enough to solve the pollution problems. Our ministers are approving/allowing industries to discharge wastewater into our natural rivers and lakes by getting some money without considering our environment. Tripur (Erode Dist) is one of the best examples in Tamil Nadu. Industries located around Tripur are discharging their effluent without any restrictions by the help of politicians. It was estimated that 6 out 10 people in India will not have enough water for their basic needs by the year 2025. Our current health Minister(mani/money, he hided the outbreak of chikun guniya in Tamil Nadu. finally what happened??? People are affected. He wanted to show/pretend that they are doing well in their duty. Pollution prevention laws should be enforced in a strict manner. Otherwise we cannot have a sustainable environment for our future.
