One day Hari took Mangal to see his field where paddy was cultivated. Mangal asked Hari what you’ll do with stubble after harvesting. Hari replied, he will keep some and burn the rest. Then, Mangal told him that it causes damage to our lungs as poisonous gas comes out of the smoke and it also affects fertile soil. But nowadays manure, straw and mushroom compost can be made by it. He also told him that it is punishable to burn stubble. – Sharwan, Chetna NGO.
