Why are green belts rarely seen in European and American countries, but China is planting them on a large scale? Is there any secret?

> > Did you discover it? In European and American countries, there is almost no shadow of green belts, while Chinese streets are full of dense bushes, bougainvillea, and creepers under viaducts. Don't Europeans and Americans often call themselves environmentalists? Why are green belts rarely seen in European and American countries, but China is planting them on a large scale? Is there some unknown secret? >

Friends traveling to European and American countries can easily find that in addition to reinforced concrete and concrete, there are cars parked temporarily on both sides of their streets, and the only green color may be the traffic lights at the intersection. However, China has always put greening in an important position in urban construction. As of 2020, the green coverage area of ​​China's urban built-up areas has reached 1,494,500 hectares, and the green coverage rate of urban construction areas is as high as 38.22%, which is enough to see China How much attention is paid to urban greening.

In areas outside the city, greening projects are also being carried out in an orderly manner. Afforestation, conversion of farmland to forests, and desert planting are all changing the natural environment. It is no exaggeration to say that in the hearts of Chinese people, building green belts has always been a key step in improving air pollution, avoiding soil erosion, and controlling global warming. Even when people buy new houses, they will actively ask about the proportion of greenery in the park. But Europeans and Americans who have always claimed to care for the environment, why don't they plant green belts? Does China plant green belts just for environmental protection? Let's look down.

A Bilong Road is in the middle column, sucking into the haze city to wear. The "Bilong" here refers to the green belts that can be seen everywhere in China. You may not believe it when you say it. Looking at the inconspicuous green belts, it can not only play a beautiful role. Take oleander as an example. It is not an ordinary plant. It is said that after the atomic bomb hit Hiroshima, Japan, people thought that no grass would grow. It can also effectively absorb automobile exhaust gas, thereby achieving the effect of purifying the air.

And other forms of green belts, including oleander, also have many unexpected functions. First of all, the green belt can maintain the bridge. Are you worried that the densely covered creepers under the viaduct will cause the foundation to be weak? In fact, the creeper not only does not affect the foundation, but also effectively prevents the building materials from weathering when it perfectly fits the supporting part of the viaduct. Secondly, when the road is wide enough, using green belts instead of barriers will not only make it easier for drivers to identify the road, but also reduce traffic accidents by isolating other vehicles and lights.

In addition, when we walk in the old alley, we will find that even though some trees have grown to the height of four or five-story buildings, people still do not choose to cut them off. The main purpose is not to provide shade, but to effectively Reduce the impact of noise on the normal life of residents. So green has so many benefits, why don't European and American countries plant it? Do they have any better way? Let's look down.

Why is the green belt that can be seen everywhere in China, but rare in Europe and the United States? It's not because they don't want to plant it, it's because they don't have a place to plant it. Environmental pollution gradually deteriorated after the Industrial Revolution, and it began to be taken seriously after European and American countries vigorously developed industry. Therefore, when Europeans and Americans first planned urban construction, there was no concept of greening. Even now, their cities need green belts very much. , it will also encounter obstacles everywhere because of dense urban population, insufficient street width, and high demolition costs.

In addition, the climate of European and American countries is not suitable for planting green belts. The local winters are long and summers are short, and the average temperature is much colder than that in China, which not only affects the survival of green belt plants, but also affects Europeans and Americans receiving sunlight. Priority will be given to planting herbs. The most important point is the limitation of land area. There are 43 countries in Europe, and the land area is only 10.16 million square kilometers. Naturally, there is not much usable area that can be allocated to each country. In order to maximize land use, only Ignore the green belt and make the house denser.

It is worth mentioning that European and American countries are making up for the shortcomings of urban greening in two ways. The first is to build large-scale forest parks, that is, to put the green belts in our cities to be planted around the city. The proportion of green space in European and American countries has always been among the best. The second way is a bit "bamboo shoots". They selfishly build factories abroad and release pollutants recklessly. Isn't this just shouting the slogan of environmental protection, but constantly increasing industrial pollution?
