Eco-friendly materials to build Govardhan hill replica?

To build a sustainable Govardhan hill at home, use natural and biodegradable materials. Start with a mixture of cow dung and clay to form the base hill. Add grass, twigs, and flowers for natural texture. Decorate using leaves, small stones, and organic color powders instead of synthetic paints. For flags or ornaments, use cloth or paper instead of plastic. Use clay diyas or candles for lighting instead of electric bulbs. Avoid thermocol, plastic sheets, or glitter as they harm the environment. After the festival, the clay and cow dung can be mixed back into soil as fertilizer, completing an eco-friendly cycle of devotion and care.
