"Please, all of you, go ahead celebrate an eco-friendly Ganpati and make sure that whatever happens, at the end of the day you are there to clean up and to make sure that you don't litter the city more than you already have," the 38-year-old said here.
About her own celebration this Ganpati, Kajol said: "I think welcoming Ganpati begins from the heart and I feel god is around us 24 hours, 365 days of the year. I believe in that more than just keeping a special day for Ganpati."
The Ganpati festival is full of life in Mumbai, and several Bollywood celebrities celebrate it with fanfare.
Over the past week, over 300,000 big and small idols started arriving in the city from artists' studios in different parts of Mumbai and Raigad.
