In addition to high-rise buildings, mainland cities also have green belts. However, why don't Western countries engage in a green belt that can purify the air? Who is going down the wrong path, in fact, time will tell.
Then, when did the construction of the mainland's green belt begin? Are these greening measures really necessary? Are Western countries not building green belts because they don't want to?
Greening is a tradition on the mainland
The best time to plant a tree was ten years ago, followed by now. In order to combine the steel forest with the forest of trees and flowers, the whole period even took two generations, a full 68 years.
The tradition of planting trees has existed in China for more than 2,500 years, and the ancients at that time would also plant willows and trees around the Qingming Festival, and even as long as there was an important festival, they would choose to plant a small tree to commemorate it.
In 1956, we officially put forward the goal of greening the motherland, and the concept of greening also came into everyone's eyes that year.
According to the call, the mainland will plant trees according to standards in the vicinity of cities and villages, as well as on the land near barren mountains and mountains, within 10 years or so.
In August 1973, we put forward the "Several Provisions on the Protection and Improvement of the Environment (Trial Draft)", which was also an important year for modern environmental protection.
In fact, this is a veritable good fate, because according to the official data, at the end of 2020, the green space area of cities above the prefecture-level cities in the mainland has reached nearly 2.6 million hectares.
At present, the afforestation area of the mainland is 3.998 million hectares, and the grass planting area is as high as 4.379 million hectares, that is to say, the mainland is only green land, which may catch up with the total land area of some Asian countries.
Some people may ask, is the significance of doing so much urban greening really more than planting land and building high? In fact, the mainland did not think that more land could realize economic value, but the results tell us that this will only lead to the exhaustion of the land and the aggravation of desertification on the mainland.
Nowadays, the presence of urban greenery is constantly purifying the air for residents, according to the data, adults are likely to inhale 11 cubic meters of oxygen and exhale the same amount of carbon dioxide in a day, and the continent is notoriously populous.
In addition to the carbon dioxide produced by breathing, the exhaust gas of oil trucks and factories also contains a large amount of carbon dioxide, and if these gases linger in the city all year round, it will inevitably affect the health and well-being of residents over time.
Therefore, although the area of urban greening is so large that it is even a pity, this is still not our end, in order to make the city's environmental quality higher and the health of the human body to rise, continue to increase the area of green space is the king.
Keeping greenery is equal to protecting the future
Increasing the green area will inevitably require additional capital investment, and some people always think that this is a waste of money. But in fact, between the gold and silver mountains and the green waters and green mountains, we are not actually doing multiple-choice questions.
In fact, the urban greening measures in the mainland are not only planting trees and grasses, but also green buildings are our pursuit. Taking 2020 as an example, the proportion of green buildings in the mainland has reached nearly 7% that year.
At the same time, there are 640,000 hectares of parks in the areas under the jurisdiction of prefecture-level cities and above, and it is under the various measures of community greening, urban grass planting and tree planting, and park construction that they have all worked together to become the "urban greening" that has achieved gratifying results.
In fact, in addition to playing a role on its own, urban green space can also cooperate with other urban governance measures.
By the end of 2020, 46 key cities in mainland China have established a complete waste classification and treatment system, and our emphasis on urban greening has also made us pay attention to the two major activities of urban waste recycling and waste recycling.
According to the data, the expenditure on energy conservation and environmental protection in cities above the prefecture-level cities in mainland China has reached 283 billion yuan that year, and in 2022, this expenditure will even reach 539.6 billion yuan.
These greenery trees can even improve the soil and reduce the intensity of direct ultraviolet rays in the city.
You must know that although the windshield forest standing outside the city prevents most of the yellow sand winds from attacking, most cities in the north still face strong winds in autumn and winter.
If there is no green vegetation to solidify the land, the bare land part of the city will be very easy to roll out of the sandstorm, so that the windy weather that is not too much will slowly form the most hated disaster climate of people, affecting normal travel.
In summer, high temperatures and strong ultraviolet rays in direct contact with the human body for a long time will also cause adverse reactions to the human body, you know, ultraviolet radiation can cause skin cancer, in 2020, the number of deaths due to skin cancer in the world is as high as 120,000.
In general, it is the money that we can create with hard work in exchange for human health that money cannot buy. The deal may not have paid off in the early days, but as the area of urban green space grows, the health and life expectancy of the mainland population will definitely improve.
The greenery of the West that is not on the table
The mainland is concerned about the health of its citizens, so will the Western countries, which are developed countries, also attach importance to urban greening for the sake of their people's health? In fact, even if they want to engage in urban greening, it will be difficult to climb to the sky.
The process of urbanization on the mainland has not passed more than 50 years, but at the same time, Western countries have already established steel giants early when we promote urbanization.
However, it is precisely because of the early development of Western countries that the process of urban greening has been hindered. Why? Actually, it has nothing to do with their urban planning.
You must know that although the cities of Western countries are very well built in terms of infrastructure, and there are countless facilities that can facilitate people's daily life, the overly dense buildings and attached hardware also make the urban land clean.
However, the emergence of the urban heat island effect will only occur when the city has developed to a certain extent, and under this reaction, the average temperature in the city is much higher than that of the peripheral areas, which will have a great impact on the health of urban residents.
But the lack of urban land available for planting has made it difficult for the authorities, and the cost of transplanting greenery from elsewhere has made it difficult for them to plant trees and grass directly in the city.
Although countries such as Germany and France have thought of other methods, such as green roofs on top of existing buildings, the cost of water supply and maintenance measures is still difficult for them to solve.
However, even if their own eyebrows are burned, many Western countries will still use the name of environmental protection to accuse the mainland of not paying attention to environmental protection on the international stage.
This can't help but make people want to ask, as a puppet state that can't take care of itself, isn't it really a clown to accuse other countries of acting?
