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.

A lot of people have the habit of reading on the toilet. But in some public restrooms in Shanghai, you won't be able to do that. If you spend more than fifteen minutes on the smart toilet there, a restroom worker will come to check on you.

According to reports, about 150 high-tech restrooms have been built in the city. Each toilet there has a sensor(传感器) that can check when a person sits on the toilet and how long he has spent sitting there. Besides, the sensor can also check the air quality inside the toilet and check the water level to save water. Beijing, Guangzhou and Shenzhen are also going to use smart toilets.

"I think it's okay with me because I don't think it's a good idea to read on the toilet," a 22-year-old young man said. However, some people aren't very happy with the smart toilet." This could be embarrassing for me. Since I was a little kid, I've always spent about half an hour on the toilet. It means a restroom worker would check on me twice. This makes me nervous." another person, Mr.Liu said.

In fact, the smart toilet is part of China's effort to use artificial intelligence(AI)(人工智能) in different areas of life. Now technology is being used almost everywhere. More than 700 cities in China have planned or are in the process of building smart infrastructure(基础设施). Our life is becoming much smarter and easier, isn't it?
