The mass production of plastics started nearly 70 years ago. Over the next two decades, the volume of the production increased twice.
A new study by the University of Hawaii has found that plastic bags are responsible for greenhouse gas emissions when they're exposed to ultraviolet radiation. Plastic bags release methane and ethylene, two dangerous greenhouse gases.
Plastic bags have now become a great threat to our environment. Bangladesh was the first country to ban plastic bags, but people still use them because of the lack of enforcement. These bags are clogging up Dhaka's drainage system. The authorities should enforce the ban again and encourage people to use alternatives such as jute-made or paper bags.
