Sample 1: pollution-free water. Water is the source of life. Water pollution is very serious now. The clean stream in my hometown is gone. More and more factories are opening, and sewage is discharged directly, resulting in worse and worse water quality. Although the state has begun to control it, it has achieved little. Some "dirty" factories are still discharging pollutants at will. Although we all drink pure water now, it looks clean, but do you know the bacteria in it?
Second: fresh air. Many people may not pay attention to the surrounding air quality. In fact, the air we breathe every day contains many harmful gases. People who have experienced smog should know how important fresh air is. Once our air is not fresh, it is easy to get sick. If you often walk in the forest, you should feel that the air in the mountains is very different from that in the city. If we don't strengthen environmental protection, it will be difficult to breathe fresh air in the future.
Third: green pollution-free food. I believe everyone knows the reasons for the recent rise in pork prices. But this is beyond our control. In the future, safe and pollution-free foods will become very valuable, especially those green foods in rural areas will be very popular. After all, people still attach great importance to good health. Now I often hear that there is something wrong with food testing. Ma Yun's prediction of the three most precious things in the next 10 year is reasonable. What's the use of a house and a car if you are in poor health?
