    At a meeting of the State Council, China's Cabinet, on Tuesday, Premier Li Keqiang said it is important to keep the social insurance premium（保险费） policy stable（稳定）, which to a large extent has eased people's worries at a time when a new regulation on premium collection has aroused public concern.

    The general offices of the Communist Party of China Central Committee and the State Council recently issued a reform plan for tax collection, which includes pension, medical, unemployment, occupational injury and maternity insurance will be uniformly collected by the taxation authorities from Jan 1, 2019.

    In fact, the taxation authorities have been collecting social insurance premiums for more than one decade. Social insurance premiums in 19 provinces and regions are collected by the local taxation authorities.

    In particular, companies have expressed concern over the uniform collection of social insurance premium by taxation authorities mainly for three reasons.

First, the new regulation indicates the reform of the collecting system as a result of institutional reform of the State Council. The companies are worried especially because they believe compulsory collection of social insurance premium will increase their expenditure on social insurance.

    Second, since the taxation authorities are fully in charge of social insurance premium collection, the companies fear that the establishment of a new collection system will prevent enterprises escaping paying the social insurance premium.

    Third, the media have reported that lately the local authorities in provinces such as Jiangsu, Heilongjiang and Hubei have been ordering enterprises to pay the arrears （ 欠 款 ） in social insurance premium they should have paid in the past years.

    These factors have increased the companies' concern over the new premium-collection regulation. Some people assume the reform will increase the companies' cost, and some companies have even begun to lay off employees fearing that “winter is coming”.

    Thanks to the current premium-collection system, the companies have managed to not pay a huge amount of social insurance premium. Take urban workers' basic pension insurance for example. It is estimated that the companies have paid only about two-thirds of the total amount of social insurance premium. Calculating on the basis of the data for 2017, this year the actual social insurance premium collection is 3.34 trillion yuan ($487.71 billion), while the total amount should be 5.08 trillion yuan. The due amount is more than one-third of the total that should have been paid.

    Eco City Farms is an educational nonprofit organization. It seeks to empower the community by teaching economic development, job training and a healthier way of living. The group has set up farms near automobile repair businesses and fast food stores in urban neighborhoods.

    Social activist Margaret Morgan-Hubbard founded Eco City Farms. She says that lack of fresh produce is a major health problem for children and their families living in Maryland. "What's critical is that 70 percent of the people in these towns are either overweight, have some illnesses, for example, diabetes, or have other kinds of diet-related ailments because they don't have access to healthy food.

    Eco City Farms offers several programs for agriculture, food and finding jobs with environment-friendly businesses. People can also learn how to cook healthier foods and teach others how to prepare meals. On a recent day, Philip Sidibe demonstrated his cooking skills. He prepared Aloco, a popular food in Cameroon where he grew up. He and other young people not only cook their food, they also grow it in a large garden.

    Tameka Barbour-Gaskins lives in Autumn Woods. She says her whole family is eating healthier meals because of the local produce. "I like junk food. I like quick meals. Not easy to just go from eating a certain way all your life to switching over to being healthier… With the urban garden here, with my son learning, he can help me switch around my style of eating. I want a healthy family."

    Margaret says the urban garden is an agent for change and the young people are its newest supporters. "Our program is about planting seeds. It's about planting seeds not just in the ground, but in other human beings so that the movement can grow and it's really exciting because these young people will be working with us throughout the year to help plan the actual farm and to finally own it."

    The environmental group Heal the Bay organized a beach clean-up. And I was one of the volunteers. We went to Venice Beach to clean up the trash.

    At first glance, the beach didn't look dirty at all. But then I saw a Styrofoam(泡沫)cup half buried in the sand on the beach. I pulled hard and finally got it out. As we moved farther, we found pieces of Styrofoam spread all over the sand. The Heal the Bay representative had told us that these little pieces of Styrofoam and other small pieces of plastic are what actually harm sea life most. Sea animals eat the plastic. After eating it, they think they are full. As a result, they can die of starvation as they are cheated by their feeling and don't think they need to eat any food.

    We kept on picking up the trash. Then I saw someone with a full Heal the Bay trash bag and I went to see what was inside. When I opened the trash bag, I found everything from a pair of old jeans and a brown belt to headphones and some plastic bags. It made me very angry with the people who left their things behind without thinking what effects they might have on the ocean.

    It is really important to protect the ocean. The ocean covers 70 percent of the Earth's surface. A clean ocean not only helps animals in the ocean survive but also helps us survive.

    By noon, the sun was shining and the temperature was rising. The volunteers that had spread out across Venice Beach were coming back to throw the trash they had collected into the truck. I could not believe how much trash there was. All together we collected more than 135 bags of trash. I do hope that next time people go to the beach, they will stop littering.
