KATHMANDU, Dec 18: Urmila Thapa had stopped using plastic bags around three years ago. She had developed a habit of carrying cotton bags to grocery shops, cosmetic outlets or garment stores. She would even make an extra effort to hand over plastic waste separately to garbage collectors. A local of Chandragiri Municipality – 14, Kathmandu, she wanted to make sure that she played a role in curbing environmental hazards. However, it's been some time she is no more that concerned.
