Polluted Festivals

This title may create a problem for somebody. I observed lot of festivals carefully but the output of all that festivals are pollution. I observed Holi, Ganeshotsav, Diwali, Dasara etc. All this festivals have common factor that is pollution.
TodayGaneshotsav is being celebrated at everywhere. The purpose of Ganeshotsav is that people should meet each other and enjoy the festival and try to solve the problem of society.
No one can remember this purpose. everybody is so much busy to celebrate the festival that no one in thinking the problem of pollution.
During the Ganeshotsav noise level would be at 90 to 110 decibels. The normal noise level is at 45 to 65 decibels which is far more less than actual level. The fire crackers also creating huge air pollution. Sulphur dioxide, carbon dioxide, smoke are the contents of air pollution. This could cause different breathing diseases. The water is polluted from artificial colour, plaster of paris which used for modelling of lord Ganesha. Already India have shortage of water resources and we are polluting them.
The solution of this problem is that we should make a awareness in the people about that thing. Also government should strictly implementing the laws regarding pollution. The VISARJAN of Ganesha should be in artificial wells, so the common water resources would not be polluted. The NIRMALYA generated during the festival can be used as a organic fertilizer. Fire cracker should ban by government.
