The benefits of the environment for China, has been gradually highlighted, after the north-south water diversion project, there is equivalent to half of the Yangtze River water flow every year, through the canal, replenished to the entire northern region, whether it is Xinjiang, Qinghai, or located outside the Guanwai Northeast three provinces, have been a huge supplement, this era, China's water resources, not so lacking in later generations, but the north gradually lacks water, more than 2000 years ago, the Hetao area and the Guanzhong region, itself is a rich agricultural town, But with the development and change of history, it has gradually changed, and now, driven by the abundant water, it has begun to regain the style of the Han and Tang Dynasties.

In the area around the direct trunk canal of the north-south water diversion project, the entire northern region bounded by the Yellow River, because of the rise of irrigated land and groundwater level, the central and western regions have increased by 10% of the fertile land, and China does not have any grain requirements for the central and western regions, and even because of the convenience of the railway, there is no need to grow grain in various places, as long as it is well stored and transported, it can be quickly transported from one place to another place. In feudal society, in the case of relying entirely on manpower, it may be transported thousands of miles away, and the cost will be too high to bear, and the generation of grain that is often transported to the front line is behind the huge consumption of three bags or even five bags of grain.

This point has been solved in the emergence of airplanes and trains, a train of more than 2,000 tons of transportation, the consumption is not high, Southeast Asian grain producing areas, at most two days, can be transported to any corner of China, because food has been concerned, and the improvement of food technology, grain production has gradually expanded, China's grain prices have been very stable.

The biggest difference between China and later generations is that grain has not risen to the level of national fortune, and grain reserves have been made, but more of it has optimized the grain structure and replaced the original ordinary grain with more scientific and higher nutritional value.

The northwest has increased 10% of the fertile land, which does not mean that the farmland has increased by 10%, this 10% is quite outstanding, changed to other uses, and even wasted his talent, which has to be reclaimed, at the border, agriculture is not very important, but if there is a basic increase in farmland in the local area, there is no need to ignore it, the locally produced grain is the basic support for the local area, and there is no need to call it from other places, and the precious transportation capacity can be placed in more important aspects, and a large number of labor can also be solved on the spot.

Of course, relative to the increase in basic farmland, the real increase is more forest, China's forest coverage, since 1908, is basically reversed, even in Baotou is still only a border town when Yang Yuanzhao did not give up, for the impact of the environment, as many trees can be planted, as many trees as you like, after becoming the leader of the country, use their influence and action to promote nationwide afforestation.

Planting trees and transforming the environment is always beneficial and harmless, and plants imperceptibly affect the environment, so that the environment is getting better and better, because the benefits brought by the environment are also growing rapidly, and the facts have affected China. Since 1911, after the Northwest became China's domination, the forest coverage of the whole of China began to increase rapidly, especially after the completion of the first project of the north-south water diversion project, which meandered from Lake Baikal through many waters, and finally injected into the canal of Xinjiang, injecting vitality into the desert near Xinjiang.

Deserts are deserts, water resources are very scarce, even if they are specifically for the climate, some drought-tolerant crops are planted, but it is very difficult to ensure the successful growth of these crops. In the windbreak forest in the area where desertification is more serious, the maintenance of the sand-proof forest may have to send people to water every year, in this way, it is not possible to ensure that all the trees are in stock, and they also need to be replanted, but now, with the emergence of root irrigation, the lake water sent from Lake Baikal can enter these places in the northwest desert through thousands of miles, and through root irrigation, directly irrigated to the shrubs that need it, irrigated from the roots, avoiding the loss of transpiration, and the efficiency of water resources utilization has been improved a lot. The increase in forest cover has been considerable.

According to the current data of the national forest department, China's forest coverage rate is increasing at an average annual rate of 1.5%, and it is expected that in 10 to 15 years, China will basically complete the forest coverage rate of more than 55%, becoming a country truly surrounded by forests.

Even now, afforestation has just begun, but the first batch of shelterbelts and a large number of self-growing forests to promote, the benefits are huge, the environment of the whole of China, has been significantly changed, since 1913, China's disastrous weather has been significantly reduced, from the Siberian cold current, almost impossible to cross the Yellow River, affecting the entire North China, the huge forest brings for water and soil, for the protection of water, but also makes the use of these two aspects more efficient, The abundance of oxygen brought by the forest and the changes of various microscopic environments, not to mention the many cash crops that follow the forest, some of which are consciously planted, such as apples, pears, oranges and other fruits, and some are naturally grown, in a unique environment, these fruits have grown well, and have obtained huge benefits every year, greatly supplementing and enriching the national food structure.

The emergence of forests, the promotion effect, is imperceptible, even more than a part of the forest, ordinary people may not feel, at most just feel, recently more comfortable than before, but in the monitoring data of the Central Meteorological Observatory, from 1910, until 1916, the hydroclimatic characteristics of every place have, and now there is no systematic, intuitive climate indicators, but the current performance, such as the reduction of dense fog weather, the proportion is not high, but it is steadily decreasing, With the increase in sunny days, the particulate matter in the air is decreasing, the oxygen content is slightly increasing, and the activity in the air is greater.

These are the reasons for the good weather, the overall climate changes, so that the temperature difference has been effectively alleviated, so far, every year because of the respiratory tract, even the temperature difference drop is larger, and the number of diseases has been reduced by at least one-seventh.

There are many benefits brought by the climate, not to be counted one by one, it is the benefits brought by this climate that China has begun to pay attention to the climate, not only the land, but also the ocean. With 18,000 kilometers of coastline, the area of the continental shelf is even larger than China's land Now, those continental shelves that should have been comprehensively developed, contain countless resources, and can even be planted like farming, are also a blank in the 21st century, but now they are being applied in advance.

In addition to China's traditional coastal and continental shelves, China controls a larger territory, especially the island countries in Southeast Asia and the Pacific Ocean, and the scope of the continental shelf is even larger, and almost all the oceans near the islands are continental shelves.

The continental shelf, as the most important part of the ocean, is not only the future, a variety of resources are only a few points away, but also the most concentrated place in the sea, the sea is boundless, but in the sea, suitable for the survival of organisms, but only in the shallow sea continental shelf, because the foundation of the ocean, aquatic plants, almost all survive on the continental shelf, the deep sea is not nothing, but it is relatively rare, far from the offshore continental shelf like a dense forest of all kinds of seaweed.

Yang Yuanzhao is not studying oceanography, but he seems to have seen an article, specifically about the ocean, take seaweed as an example, the difficulty of planting seaweed, is more difficult than planting food, and it is affected more, but seaweed must form a scale, especially in the case of forming a forest, the economic value that can be generated by an acre of seaweed is much higher than that of forests and food, the ocean is a three-dimensional structure, and the longest seaweed can extend for hundreds of meters, except for a few types of seaweed, which can be consumed by humans. Most of the seaweed is plankton, food for fish.

The unique biological environment of the ocean, so that seaweed, is the main provider of oxygen, but also the most fundamental source of food for marine organisms, the ocean is far larger than the land, once enough seaweed is put in, the bottom of the herbivorous torpedo, can get enough food, and then attract more fish to come, from plankton, to crustaceans, to fish, and finally to carnivorous, and finally form a complete biome, the complete biome is the most stable, he can continue to generate resources.

Before China, the large reduction of offshore fish is due to the fact that China's fishing efforts are too large, and the fishing efficiency of trawlers is not known how many times higher than that of traditional fishing boats, even if the size of the mesh is strictly controlled, it will inevitably cause a significant reduction in fish, and on the other hand, it is because the total amount of fish resources near China's shallow continental shelf is small.

Although fish live in the ocean, there is a basic principle, that is, food, without enough food, fish can not grow, the size of the population can not be expanded, this food, but seaweed, these marine plants, can also be cold and warm ocean currents converge, set off the bottom material, the former can be changed, the latter can not be changed, the whole world, cold and warm ocean currents converge world-class fishing grounds are only four, currently in Hokkaido is in the hands of China.

Even if it develops to the next generation, or even looks forward to two or three hundred years, the world cannot go to the extent of controlling the ocean and controlling ocean currents, that is almost to the premise of a thorough grasp of the entire climate and tides, etc., it is impossible to artificially create ocean currents, then it is possible to plant trees, among marine algae, the best of the best, similar to the way of land breeding, generation after generation of improvement, subtly, can produce dominant varieties, as long as the cultivation of these algae increases, to the seabed of Chinese mainland, To create an underwater world full of life and vitality, the total number of fish is sure to increase several times.

At present, the vast majority of countries in the world have not gone to the ocean, but in the future, they will inevitably go to the ocean, and the sea has become an inevitable choice when land resources and production can reach the extreme. Rather than going to the ocean to be fished and then thinking about increasing marine biodiversity, it is better to consider now, China along the west side of the Pacific Ocean, the east side of the Indian Ocean, the huge continental shelf, there are many places that can be replenished, as long as it is cultivated, to give these seaweeds the ability to recuperate, as long as enough time is waited, the seaweed will be multiplied, even ten times or twenty times the benefits, not to mention, some of the more precious seaweeds, for example, long-term use of kelp, seaweed, and some other tastes better, Edible plants of the sea with a long history are also quite economically valuable.

China's marine research, almost with agriculture almost started, in China's coastal Qingdao, Shanghai, there are special marine bases, they are not for the study of marine resources, mainly plant species, the world's seaweed is about 20,000 kinds, of which only more than 100 kinds are edible, China can not put all the land on this, just like China can not use all the land to grow food, once this is done, maybe China is not far from extinction, among the seaweed, choose a comparative advantage, Just like the selection of suitable grain, historically, the grain of all countries in the world has been selected and bred from generation to generation, and the advantages have been improved, and it has become the current high yield, and the scientific method has, to a certain extent, increased its output.

The ocean is rich, in the sea water and you, rich in a variety of minerals, these will give seaweed sufficient nutrition, then how to make reasonable use of these parts, increase the production of seaweed, enhance the ability of seaweed in all aspects, the empty seabed, into a dense forest This is what China should do, once all this is done, China's nearly 10 million, or even more continental shelves, will become a piece of stronger fishing grounds, which is important for China's nutritional structure and dietary structure, There will be even bigger changes.

In the future, aquatic, especially saltwater fish, in all aspects of high-quality performance, compared to freshwater fish, are comprehensively surpassed, become a good nutrition, and Japan's longevity, is thanks to Japan's frequent food of marine fish, China than Japan is much larger population, to reach the level of Japan, the demand for marine fish, is simply unparalleled, in this case, if China does not take precautions, until the last case, everything is too late, China to really crazy expand the population, Coupled with the current treatment and consumption, I am afraid that the world's oceans will not be able to withstand China.
