How do you deal with plastic bags from the supermarket? Throw them away or reuse them? How about eating them?

Envigreen in India has made a bag with 12 natural ingredients(食材)，such as potatoes, vegetable oils and bananas. It looks and feels just like the usual plastic bag, but can break down. The bags aren't harmful to the environment. Both humans and animals can safely eat them. The founder of Envigreen, Ashwath Hedge, spent four years trying them out.

Although the Envigreen bags are much more expensive than those usual plastic bags, they are good for our environment. Usually, it takes about 1000 years for usual plastic bags to break down. But an Envigreen bag can naturally break down in less than 180 days. It also dissolves(溶解)in less than a day in water, and in about 15 seconds in boiling water. Maybe the Envigreen bags are a solution to the world problem of plastic pollution.，
