Ganesh Chaturthi is one of the most celebrated Hindu festivals across India and will be celebrated this year in early September. An article in The Hindu, comments on the fact that over the years, the festival is being celebrated on a larger and larger scale; saying, “once a fairly quiet, mostly private practice, Ganesh Chaturthi now involves large, public festivals in many parts of the country”. 

However, along with the festival itself, each year we also see lots of articles deploring the pollution caused by it. But what exactly is the impact Ganesh Chaturthi celebrations have on the environment?

What is Ganesh Chaturthi and how is it celebrated?

Idols of the god are placed both in households and in various public places and offerings (including flowers, food, ghee, and more) and prayers are given. 

After the 10 days of Ganesh Chaturthi, the idols used in the festival are sent off with a “visarjan,” or immersion in a body of water. While this is meant to symbolise the impermanence of the mortal world; this nonetheless leaves a very permanent impact on the environment. 

How does Ganesh Chaturthi harm the environment?

PoP contains calcium sulphate hemihydrate, a material that takes anywhere between months and years to fully dissolve in water. In doing so, it reduces oxygen levels in the water, killing the fish and other aquatic life. 

In addition to this, these idols are often coloured with bright paints that contain heavy metals such as lead, nickel, cadmium, and mercury. These heavy metals can affect the PH balance of the water; making it more acidic and thus further poisoning its inhabitants. Additionally, these materials can cause skin diseases in humans when they come into contact with the water, as well as poisoning us through the fish and birds eaten as food.

Other solid wastes

They are often decked with flowers, plastic decorations, camphor, and even polystyrene (also known as thermocol). All this solid waste also ends up in water bodies, further straining our already polluted rivers and lakes. Even the flowers, which are usually bio-degradable, often have pesticides and fertilisers that leech into the water. 

This pollution has various effects. The solid waste blocks the natural flow of water; which can cause stagnation and the breeding of mosquitoes and other harmful pests. With nowhere to go, the water ends up being further polluted by other forms of waste. The end result is huge amount of water pollution that poisons our water bodies for years. 

Measures by the government

Ganesh Chaturthi in Mumbai, INDIAEvery year the government spends crores of rupees in an effort to clean out the garbage that pollutes our lakes and rivers in the months after the festival. In an effort to combat this, many measures have been taken by the government. 

In Hyderabad, new ponds and tanks were built especially for the immersion of idols, and in Bangalore, a fixed number of water bodies within the city were designated for immersion in a bid to decentralise this practice. The Bruhat Bangalore Mahanagara Palike (or BBMP) and the Karnataka State Pollution Control Board (KSPCB) has taken this a step further and banned the use of PoP idols altogether. Instead, it is promoting the use of idols made with quick-dissolving clay and painted with natural colours. 

Dr K Sudhakar, Chairman of KSPCB, said, “As they have proven to be toxic to both nature and human beings, we in the Board have decided to curb the sale and use PoP idols in the state”. However, the effectiveness of these measures remains to be seen. Such measures have been previously implemented in both Tamil Nadu and Goa but were quickly overturned.

So what can we do?

  1. Choosing idols made out of organic non-baked clay that dissolves easily. These can be painted with natural colours, such as those used in foodstuffs. Additionally, these can also have fish food or seeds embedded in them. 
  2. More permanent idols, such as those made out of metal or stone can also be used. And in this case, worshippers can undertake a more symbolic immersion; such as that of a betel nut, and continue to use the idol itself for a number of years. 
  3. Removing the non-organic decorations before immersing the idol
  4. Avoid using public water bodies, like tanks and lakes, especially for household idols; so that we take the pressure off water bodies that are already under the pressure of sewage discharge and industrial effluents

So, as festivals should be a time of joy, let us try to make Ganesh Chaturthi a festival favourable not only for us, but also for the environment.
