Gov't Should Help Alter Decades-Old Traditions, Encourage Indian Farmers Not to Burn Stubble

Traditionally, farmers burn stubble twice a year - in summer and at the beginning of winter after the crops have been harvested. During March and April, the warm breeze disperses the smoke quickly. However, during September and October, plummeting temperatures and low wind speeds can cause the smoke to travel up to 250km (155 miles).
