Nothing can be absolute, only possible. However, judging from the current direction of the development of human civilization. I feel uncertain about the future of humanity.
Looking at the world, isn't the so-called developed and high-tech all overdrawing the only resources that the earth brings to human beings?
I feel uncertain about the future of humanity.

Aside from the fact that the ocean is the breadbasket of the future, what else could be the breadbasket of the future.
In addition to the ocean, the possible granary of the future has the following aspects:1The use of modern agricultural technology to improve the yield and quality, so that some specific areas into celery rock mold into an important grain production area.
For example, regions such as China's Northeast region, the U.S.'s Midwestern corn-growing regions, and Russia's Black Earth Belt have abundant food resources with the help of modern agricultural technology. 2.The waste of large industrial enterprises such as coking plants and paper mills can be used for agricultural production such as planting fungi and edible fungi, thereby increasing food production.
For example, a large number of Chinese herbal medicine cultivation bases in China have been built on abandoned cement factories. 3.Some of the wasteland can be used to reclaim farmland to increase food production.
For example, in some desert areas in northwest China, large tracts of arable land have been created for growing crops through artificial cultivation and rational use of water resources. 4.Cultivating traditional agriculture and natural farming methods, emphasizing sustainable and sustainable production, and growing food in Zao Township in a way that minimizes pollution and environmental damage.
This trend has been strengthened in the current trend, and many farms producing organic food have emerged in some countries. To sum up, the granary of the future is not limited to the ocean, and other areas may also become food production areas. In the future, agricultural technologies and management methods based on sustainable development will help solve the problems of growing populations and food scarcity.

A: Because the ocean provides us with food to meet our nutritional needs
1) The annual production of seaweed is large, which can provide sufficient protein. Wang took this.
2) Plankton is abundant in the ocean, which can be processed into food.
3) There are many fish and shrimp, and there is still fishing potential to be tapped.
4) There are still many marine organisms that have not yet been exploited in Zhizhou.

1. Selfless and stingy.
2. Abundance and shortage.
3. High and low.
3. 1. Mineral resources, food, electricity, fresh water, and the construction of cities.
2. Only by protecting the ocean and marine resources will we be willing to make its dedication.
4.1. The ocean is the breadbasket of mankind's future.
2. Algae, plankton, fish and shrimp.
3. Column numbers. The high production of Antarctic krill is quantitatively illustrated by a column of figures, which is more accurate on the one hand, and more convincing and convincing on the other.
Give an example. By giving the example of Antarctic krill, it is shown that the ocean is the breadbasket of the future, which can be turned into concrete, and the content of the explanation can be concrete, clear, easy to understand and convincing.
Comparisons. By comparing the annual production of Antarctic krill with the annual catch of the world today, the reader will have a concrete and vivid impression of the future production of Antarctic krill.
4. The ocean and we are a whole, first of all, the ocean itself has a huge purification capacity for pollutants such as transport, dilution, diffusion, oxidation, reduction and degradation. However, this capacity is not unlimited, and when the local sea area receives more toxic and harmful substances than it can purify itself, it will cause pollution in the sea area. In addition, although the ocean contains many resources, it takes time for marine resources to regenerate, and if we develop marine resources without paying attention to protection, then these resources will always be used up one day.
Therefore, it is extremely important and necessary to protect the oceans.

Hey, the ocean is very rich in resources, but it is not easy to deal with it, it is seriously polluted, it will become a granary, and it will also become a garbage dump.

(1) No, because "the most serious environmental problems faced by mankind" are not only population growth, resource shortage, but also environmental degradation and other factors (Note: the article "Population increase and resource shortage, this is one of the most serious environmental problems facing mankind today" is actually a sick sentence!! One of the "how can there be so many things in front of you!!
2) Because this article is mainly about "the ocean is the breadbasket of the future of mankind", other factors are irrelevant to this article, so they are ignored.
3) It is impossible to judge because the reference to "one" is unclear.
4) Give examples, list numbers, and make comparisons.
5) This can be scribbled.

(1) Reasonable (2) Give examples, make comparisons, and list numbers. There is great potential for marine exploitation.
Brother, it's not easy to type so many words!

1.No, because "one" means that there are other most serious environmental problems;
2.Because the main purpose of this article is to introduce "the ocean is the breadbasket of the future of mankind".

The ocean is the breadbasket of the future.
Resource scarcity is one of the most serious environmental problems facing mankind today. Whether or not this problem can be properly resolved has a direct bearing on the future life and death of mankind.
One of the manifestations of resource shortage is the shortage of arable land. Due to the lack of arable land resources, the growth of food production has not kept pace with the growth of population. It is out of this realization that many people have issued warnings:
The planet will not be able to feed more than 10 billion people. However, some optimists oppose this alarmist claim. They believe that although the development of arable land on land is nearing its limit, the earth still has a vast ocean to be developed, and it is entirely possible that the ocean will become the breadbasket of humanity's future.
Of course, what the ocean can provide us with is not the traditional food – rice, wheat and corn – but the broader food – other foods that meet the nutritional needs of human beings. Some oceanographers have pointed out that seaweed, which grows naturally in offshore waters, grows 15 times the current annual world wheat production.
If these algae are processed into food, they can provide enough protein for humans.
In fact, we are no strangers to using algae as food. As far as China's coastal areas are concerned, the edible algae that people are more familiar with are: brown algae kelp, wakame, hijiki, sargassum, red algae seaweed, partridge cabbage, cauliflower, green algae Ulva and Turquoise.
In recent years, new species of algae have been cultivated, and the production of these algae has been doubling under careful artificial cultivation.
In addition to seaweed, the ocean is also rich in plankton that is invisible to the naked eye. Some people have calculated that if they can be caught and processed into food without destroying the ecological balance, it will be enough for the needs of 30 billion people.
As for the many fish and shrimp in the ocean, it is a familiar food. Due to overfishing and marine pollution, the number of fish and shrimp in the offshore waters is nearing its limit, and many countries are constantly fighting for the limited resources in the offshore waters. But we can also open up distant-water fisheries and develop deep-sea fisheries.
For example, krill in Antarctica can produce up to 5 billion tonnes per year. As long as krill is caught at 100 million tonnes per year, it is more than double the annual catch of the world today. Moreover, there are still many marine living resources in the open ocean and the deep sea that have not yet been fully exploited and utilized, and their huge potential is self-evident.
To sum up, we say that the ocean has every chance of being the breadbasket of humanity's future.

Seawater DC cooling technology has a history of nearly 100 years of development, and the relevant anti-corrosion and anti-marine organism attachment technology has been basically mature. At present, China's seawater cooling water consumption does not exceed 14.1 billion cubic meters per year, while Japan is about 300 billion cubic meters per year, and the United States is about 100 billion cubic meters per year, which is a big gap. Seawater circulating cooling technology began in the 70s of the 20th century, and has been widely applied in the United States and other countries, which is one of the main development directions of seawater cooling technology. >>>More
