Green lawn should not be cut too short

<

Yesterday, a lecture on the environment management of livable cities was held at the annual meeting of the Science and Technology Association. Dr. Li Wei, executive director of the China Ecological Association, gave the audience a wonderful and practical environmental protection lesson.

The windows of many citizens’ houses are covered with dust. Once the wind blows, dust is blown into the room, which can easily cause respiratory diseases. Li Yu suggested that citizens clean the windows once a week.

"The green lawn should not be cut too short. The green space on both sides of the road should not be higher than the ground. The parking lot can be paved with gravel to cool down and reduce dust." Li Wei said that the green lawn can have a dust removal effect of more than half a foot. However, in many cities, the lawn is cut short. In fact, it is a pity that the lawn is cut so short that it does not function as a dust collector. It also increases the evaporation of water and wastes water resources. Li Wei also pointed out to everyone a wrong phenomenon. The green belts on both sides of many urban roads are higher than the ground, and roads and green belts are separated by road grave stones. She believes that this practice is not conducive to dust reduction. Not conducive to the absorption of water in the green belt.
