Pollution is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. According to a study - Water pollution causes approximately 14,000 deaths per day, mostly due to contamination of drinking water by untreated sewage in developing countries. An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die of diarrhoeal sickness every day. Nearly 500 million Chinese lack access to safe drinking water. 656,000 people die prematurely each year in China because of air pollution. There is a immediate need for potential pollution prevention and waste minimization techniques. When Wastes are reduced or eliminated, substantial economies can be realized by reduced expenditures for pollution control equipment, and lower treatment and disposal costs. To carry forward the awareness and the message, World Pollution Prevention Day is observed annually on every December 2.
Events - Various functions are held in educational institutions to award prizes to winners of elocution and drawing competitions. Various eco-clubs of schools and colleges spread the message of pollution prevention. Leaflets and information brochures are distributed by the government and NGO's advising the use of public transport and using more eco-friendly products in our daily life.
