As the world's population continues to increase, so does the amount of global waste. According to data (数据) collected by the World Bank Group, nations are on pace to produce 4 billion tons of waste every year by 2100. Many experts are calling the problem of global waste a worldwide health crisis (危机) because the waste is polluting the world's oceans, air and soil and is putting the health of all living things in danger.
For years, governments have been telling citizens that living a zero-waste lifestyle is the way to go. Now some stores are helping people do that.
Most grocery stores produce waste when they throw away food and packing material. In some cases, the food consists of fruit and vegetables that don't look good any more. In other cases, it's packaged food that is nearing the "sell-by" date printed on the package. After the "sell-by" date passed, the food is not considered safe to eat. Thus, many stores throw out unsold packaged food before that date arrives.
To solve this problem, business people are opening smaller grocery stores. Instead of selling food in packages, these stores offer it in open containers (容器). Customers bring their own bags or clean containers to the store. There, they fill their bags or containers with everything from nuts and grains to oil and vinegar. They pay for only the amount of each product that they need. Zero-waste stores often sell fruit and vegetables as well. When these goods start to look old, they're sold at a cheaper price or given to the poor people. Inspired by these smaller zero-waste grocery stores, some large supermarkets are taking similar steps to reduce the amount of waste that they produce.
