The Maha Kumbh Mela 2025 in Prayagraj launched the 'One Plate, One Bag' campaign to promote environmental sustainability. Over 70,000 cloth bags and 2 million steel utensils were distributed to replace single-use plastics. The initiative aims to make the Kumbh Mela a model for eco-conscious large-scale events, reducing plastic pollution and promoting responsible environmental behavior among pilgrims.
