Plastic bags are difficult and costly to recycle and most end up on landfill sites where they take around 300 years to photodegrade. They break down into tiny toxic particles that contaminate the soil and waterways and enter the food chain when animals accidentally ingest them. But the problems surrounding waste plastic bags starts long before they photodegrade. Our planet is becoming increasingly contaminated by our unnecessary use of plastic bags. In Dhaka city, about 14 million pieces of plastic bags are thrown out every day, often ending up in rivers and oceans.
