Using eco-friendly Ganesha idols for Ganesh Chaturthi is important for several reasons:

1. **Environmental Protection**: Traditional Ganesha idols made of Plaster of Paris (PoP) are non-biodegradable and often contain harmful chemicals like lead and mercury. When these idols are immersed in water bodies, they pollute the water, harm aquatic life, and degrade water quality. Eco-friendly idols, made from natural clay or biodegradable materials, dissolve easily without causing harm to the environment.

2. **Health Benefits**: Chemical paints used on traditional idols release toxic substances into the air and water, which can be harmful to human health. Eco-friendly Ganeshas are often painted with natural dyes, reducing the risk of exposure to harmful chemicals.

3. **Promoting Sustainability**: Choosing eco-friendly options encourages a shift towards sustainable practices. It promotes the use of materials that are renewable, reusable, and less harmful to the planet, contributing to a more balanced and responsible way of celebrating festivals.

4. **Support for Local Artisans**: Many eco-friendly idols are handcrafted by local artisans using traditional methods. By opting for these idols, you support local economies and preserve cultural heritage.

5. **Raising Awareness**: Using and promoting eco-friendly Ganesha idols helps spread awareness about the importance of environmental conservation, inspiring more people to adopt green practices in festivals and daily life.

By choosing eco-friendly idols, devotees can celebrate Ganesh Chaturthi in a way that honors Lord Ganesha while also protecting the earth.
