As the last hope for world food, the ocean not only has greater possibilities, but also once the ocean environment improves, various organisms between regions will be a comprehensive promotion. If you invest any penny in the future, you can get ten times or even hundreds of times the profits.

The process of moving towards the ocean was just a coincidence at the beginning. On the premise that agriculture has developed to a certain extent, some experts in the ocean proposed to ask for it from the ocean.

Of course, it is not fishing. Fishing is the easiest. As early as countless years ago, even in slave society and even primitive society, there were people on the seaside asking for it. In most cases, the ocean was generous, as if there was never an end for fish. However, for the technological conditions at that time, ocean fishing was a way out. The ocean was different from mountains, rivers and lakes. The windless waves mean the ocean. A slight strong wind was a nightmare for ordinary boats. People were not fish, and water was relatively in comparison. In the wind and waves, not many people could survive.

As the performance of the ship becomes better and better, offshore fishing is becoming safer, especially the emergence of trawling fishing boats, which directly makes ocean fishing the norm. However, such large-scale fishing exceeds the balance of the ocean itself. In later China, fishing in the East China Sea is not an exaggeration, which is real. On the one hand, it is the impact of pollution. In this regard, it will be gradually digested by the ocean. What really affects trawling fishing boats. Countless trawling fishing boats, like locusts, fished in the ocean, and caught enough fish, enriching the entire China's diet structure, but also intensifying the marine ecology. For example, the specialty of the East China Sea, big yellow croaker appeared in groups before the 1950s, but after the 1990s, it gradually became rare, and by the 21st century, there were almost no wild ones.

It is precisely for this reason that when oceanographers proposed to study the ocean and plant seaweed on the continental shelf, Yang Yuanzhao directly agreed, and even criticized it for the huge investment, Yang Yuanzhao also took over the efforts to make the ocean rich and not repeat the mistakes that China once did.

Currently, three inland seas have been developed in China's four major inland seas, and the governance has been well managed. Accumulated 700,000 square kilometers of sea areas have been invested, which accounts for almost 60% of the area of ​​the three major inland seas, but only about 35% of the final results have been achieved. This is the result of careful research by oceanologists, but such a 200,000 square kilometers of sea areas have achieved outstanding results. This is also the case in recent years. Not only has no one criticized the huge investment in oceans, because the output of oceans has already given them hope.

More than 20 square kilometers of seaweed have become one of the largest fishing grounds offshore in China. The annual growth rate of fish catches in these areas has reached more than 70%. This is also the annual data of sustainable development. The fish catches in the entire coastal areas have also increased by 30%. In the rapid growth, this is very helpful in balancing China's dietary structure and creating a large number of benefits and jobs.

Even Yang Yuanzhao, the initiator, did not expect that he only learned about these things from the Internet in the past. At that time, it was still in the United States. In the North Atlantic region of the West Coast, the United States released a large amount of seaweed, and even the kind of biological blankets specially used to gather seaweed, which could effectively improve the rate of seaweed and survival.

But that was actually experimental, and the funds were consumed so much. Even the wealthy United States could not bear such investment. Of course, it was in the 21st century that it was not only that the labor costs of the entire world rose to a terrible situation, but also that pollution and the entire ocean community were destroyed, so the investment was so huge that even the United States could not bear it.

But this is not more than 100 years ago, when industry has not completely changed the entire earth's environment, the oceans of the entire world have not been polluted, and the ecological balance of the entire ocean has not been weakened. In many places, only by supplementing the original foundation, the marine biological community can be restored, and thus produce unimaginable effects.

This supplement has changed China's marine ecological environment from a slow decline to a strengthening. With the gradual formation of undersea forests, a natural ecological balance has been formed. In addition to a small number of them that need to be replanted, it only takes monitoring. When the algae forests on the bottom of the sea reach a density of more than 60%, they will grow at a rate of 5% every year and expand outward. This expansion is like the natural expansion of a forest.

This expansion is very considerable, especially when the seaweed community reaches a certain level, exceeding 500,000, or even 1 million, 5% per year is equivalent to laying 50,000 square kilometers of seaweed each year. This benefit is greatly improved. The increase in the area of ​​seaweed is 5%, which is not a 5% increase in fish harvest. Fish harvest is a very special. The better the environment, the more fish it attracts, and there are many rare ones. Even the total number of fish will increase a lot. The nutritional tasks that seaweed can undertake are the basis of the entire ocean and even human activities.

Because of these harvests, Chinese seaweed cultivation has gradually expanded outward from the inland sea of ​​China. It started planting in the South China Sea last year. Compared with the three major inland seas, the total number of seaweeds is only more than one million square kilometers, but China's South China Sea is 3.5 million square kilometers. Although the area of ​​the continental shelf is not entirely, a large amount of seaweed can be planted. Although most of the seaweed grows on the continental shelf, there may not be no plants in the deep sea. Most of the South China Sea is deeper than the 200-meter continental shelf, but it has not reached the deepest point. The place where seaweed can be planted is larger.

China has not only four major inland seas. After occupying Southeast Asia and Australia, the continental shelf was large, especially in 1917, China tried to start planting near Hokkaido.

This is an innovation. Even in later generations, Hokkaido was one of the four major fishing grounds in the world, but it was more a fishing ground formed by the interaction of ocean currents. If there is enough seaweed planting, it can allow fish to form a relatively stable food structure, increase fish aggregation, and increase fish population density in the fishing ground.

Other places are also being planted. Southeast Asia's vast islands have more continental shelves, and fewer are developed here. After planting a large amount of seaweed, it will definitely be upgraded to a certain level. They will become one of the gathering places of fish in the ocean, attracting fish from the deep sea, and even creating a unique biological community. In the future, this planting will expand to the islands of Oceania and the Pacific Ocean. In the seaweed-based animal and plant communities, a complete biological belt will gradually form, increasing the chances of ocean generation.

The road towards the ocean is not easy to follow. China is also clear about this. With China's current industrial output value that is several times more than other industrial countries in the world, and it has obtained massive amounts of funds and raw materials from various countries every year. It still feels that this is a very difficult thing. Even if the profit has been obtained now, the annual increase in catches in the three major inland seas is just an astronomical growth. However, if this growth can last for 10 years, the growth of fish harvests in 10 years may only be one-half of the overall investment. This is because of no further investment. If it continues to invest, the time for recycling costs will continue to increase in the future.

When we come to China's economy, we are afraid of not low profits, but a direction of capital investment. This is also the fundamental reason why this plan has been implemented and implemented. It can recover costs in 20 years, and it seems that the annual income is only 5%. However, this absolute income is very terrible. The most important thing is that China only calculates the absolute income, only the fish harvest itself and the harvest of seaweed, but it is not calculated. For example, the value of seaweed that China does not realize, some researchers in later generations extract beneficial ingredients and medicines from seaweed, and even research on the extraction of oil from seaweed.

These are all long-term benefits. Even from seaweed to improve the ecological environment and obtain oxygen and other benefits, this benefit is absolutely not low. Even if it is not derived, a project with an investment of more than 5 trillion Chinese currency, even if it is a 5% return, the absolute value will exceed 250 billion yuan. This is difficult for any large state-owned enterprise or group to create, not to mention that the breeding industry is a century-old industry. As long as seaweed is balanced and there is no need to invest in the future, you can continuously obtain profits. Hundreds of thousands of square kilometers or even millions of square kilometers of land, this 5% expansion rate, and the chain benefits created by this item alone will increase the entire plate. Not to mention the final profit, it is just an increase of 5% from a 5 trillion plate, which is another 250 billion yuan, which is not bad.

However, the three major inland seas have invested 5 trillion yuan, and the South China Sea is at least three times higher. Near Japan, the North Pacific, the Aleutian Islands, Australia, and the Southwest Pacific Islands, the scope of these continental shelves is far above China's inland sea. If all investments are made, they may be 10 times or even more than 20 times higher than the three major inland seas.

For a country, the amount of money is just a number. The key is materials, manpower, and even resources. These are not easily transformed. Even if they are as strong as China, they can only be done step by step. They started in the South China Sea in 1917 and tried the waters in Hokkaido. Southeast Asia, Australia, and even the continental shelf of the Pacific Ocean can only be used as a pilot project, and the focus is more valuable. The rest can only be slowly calculated. It is conservatively estimated that it will take 20 to 30 years to complete all of them. As for maintenance and updates, it will take more than a hundred years.
