Ganesh Chaturthi is a 10 days Hindu festival celebrated all over India in August or September in honour of the god Ganesh, the elephant-headed.
The festival involves installing statues of Ganesh in public temporary shrines or in private homes, which are worshipped for ten days.
Then, these Ganesh statues, colorfully decorated, are immersed at the end of the festival in a body of water such as a lake, a river or the sea.
The immersion of these statues (may vary from 3/4 of an inch to over 70 feet) creates a serious impact on the environment as they are made of plaster of Paris and moreover, the chemical paints used to adorn these plaster idols themselves contain heavy metals like mercury and cadmium, causing water pollution.
