The article discusses the severe environmental threat posed by plastic pollution, highlighting its non-biodegradable nature and the harmful effects of its degradation products on human and animal health. It emphasizes the global dependency on single-use plastics, with staggering statistics on plastic bottle and bag consumption. In response to this crisis, the article introduces the 'Sonali Bag', a biodegradable and eco-friendly alternative to plastic bags, invented by Bangladeshi scientist Dr. Mubarak Ahmad Khan. Made from jute cellulose, these bags are designed to decompose within 3-4 months, in stark contrast to the centuries it takes for polythene bags to break down. The Sonali Bag represents a significant step forward in combating plastic waste and its environmental impact.
