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

    The bags are not harmful to the environment. Humans and animals can safely eat them. Indian company EnviGreen has made a bag with natural materials. It looks and feels just like plastic, but can be broken down(分解) easily.

    Ashwath Hedge who set up the EnviGreen company spent four years doing experiments (实验) with 12 natural materials. They include potatoes, corn, vegetable oil and bananas. He made the materials into liquid(液体) and used the liquid to make the bag.

    Although the EnviGreen bag is more expensive than a common plastic bag, it has many advantages. According to The Wall Street Journal, it takes 1,000 years for common plastic bags to break down. But an EnviGreen bag can naturally break down in less than 180 days. It also breaks down in less than a day in water, and in less than a minute in boiling water. Hedge was happy to show it in his interview, and he put an EnviGreen bag in water and ate it with a smile.

    There are more than 15,000 tons of plastic waste in India every day. But only 9,000 tons are processed. In China, 3 billion plastic bags are used

    Every day. Maybe the EnviGreen bag could be a solution to the world problem of plastic pollution,

    There are many kinds of pollution around us, such air pollution，soil pollution， noise pollution and light pollution, They are bad for our (healthy) in many ways.

    Burning gas, oil and coal creates air pollution. It can cause sore eyes and (breathe) problems.

    With the increase of pollution and the (develop) of industry， litter is everywhere. It makes our environment dirty. People put lots of rubbish in the land. Farmers use too many chemicals in the fields. They destroy the soil, soil pollution has became serious.

    Noise pollution can make people deaf. For example, people may lose their hearing they work in a (noise) place for a long time. Too much noise can cause high blood pressure as well.

    Working for long time in strong, changeable light may cause some kinds of (ill). It makes people feel terrible and is especially bad for the eyes.

    With (little) pollution, our planet will become greener and our health will be better. Let's be greener people.
