The pros and cons of enclosing the lake to create land will be held this afternoon

The advantages are in the contemporary, and the disadvantages are in the future.

1. It can alleviate the problem of population tension, due to the increase in population in a certain place, the per capita amount of arable land has decreased, which is not enough to maintain the local food **. In order to solve this problem, some people have proposed a plan to enclose the lake to create farmland and increase the area of cultivated land. ”

Therefore, the core of the problem is to increase the grain rate, rather than enclosing the lake to create land, and there are many ways to increase the grain rate, which can not only increase the yield per mu, but also transfer the grain. If you must enclose the lake to create farmland, you should also fully consider the adverse effects (as mentioned upstairs). After all, survival comes first.

2. It can increase the area of cultivated land.

3. The resettlement of the migrant population can be solved.

4。It is possible to increase the local GDP

5. It can solve the land problem of construction and development of industry and construction.

I oppose it, because the earth is getting more carbon dioxide, and there is a lot of vegetation near the big lakes to protect it, which can reduce the amount of carbon dioxide, thus changing the problem of the earth's glaciers rising.

Pros: In the Dongting Lake area, the population is growing, the population is dense, and the per capita arable land is small. The increase in grain production has certain benefits for the social and economic development of the lake area; The people's grain rations have been increased, and a part of the grain has been put into the market to bring about economic encirclement and land reclamation.

Paddy fields are also wetlands. It can alleviate the problem of population tension. It is possible to increase the area of arable land.

It can solve the resettlement of the migrated spring deficit population. It can increase the local GDP [gross domestic product, which refers to the sum of the market value of all final goods and services produced by a country (or region) within its territory within a year. As an important indicator to measure the comprehensive strength of a country (or region).

It can solve the problem of land use for construction and development of industry and construction. Why do many people want to dig Zheng Shenwei Lake to make fields? It is because of the lack of arable land that the reclamation of land around the lake can at least solve part of the food problem.

Solve people's eating problems. Expand the area of cultivated land, increase total grain output, improve the law of land use, and strengthen the utilization and development of resources. There are benefits to enclosing the lake to create fields.

For China, there is a large population and a lack of arable land. China is on the road of development, and increasing the area of cultivated land can increase China's grain production, and it can also build factories and buildings, so that China's economic growth will have certain benefits for China's development. China should focus on development.

To a certain extent, the area of cultivated land can be increased and the problem of people's food can be solved. It is because of the lack of arable land that the reclamation of land around the lake can at least solve part of the food problem. It can alleviate the problem of population tension.

It is possible to increase the area of arable land. The resettlement of the migrant population can be solved. It can solve the problem of land for construction and development of industry and construction.

A large number of farmers migrated to the Dongting Lake area, surrounded the lake to create farmland, built many dams, and blocked the water of Dongting Lake, making the historical "800-mile Dongting" become "300-mile Dongting". In recent years, with the development of economic construction in various localities, the water consumption in the river basin has increased sharply, the amount of water coming from the lakes has decreased, the income cannot make ends meet, the water level has dropped, and the area has shrunk, resulting in the disappearance of some lakes and the great shrinkage of the area of some large lakes.

In 1998, China experienced the great flood of the century. First of all, the process of lake swamping has been accelerated, and the area of the lake has been shrinking, and it has been difficult to regulate and store surface runoff, resulting in frequent droughts and floods. Such as:

Due to the continuous reduction of lakes in Hubei Province, the shrinking lakes have basically lost their original storage functions, resulting in the area of flood and drought disasters increasing year by year, with an average of more than 460,000 hectares in the 50s of the 20th century and more than 1.7 million hectares in the 80s. Secondly, the decline of aquatic animal and plant resources and the deterioration of the ecological environment in the lake area have led to the continuous decline of fish species and the decrease in quantity. Excessive reclamation often damages the natural resources of the lake, destroys the ecological environment and storage function of the lake. A large amount of land reclamation from lakes is prone to flooding.

I said that this is science and technology, and it is the development of science and technology that has promoted the process of mankind, and it is the development of science and technology that has enabled mankind to have this new and beautiful life. Throughout the ages, which dynasty and which generation did not attach importance to the development of science and technology? Looking back on the past, look at the four major inventions, which are unique; Look at the astronomical calendar and be amazed by it; Zhaozhou arch bridge, exquisite design; A peek at the "Compendium of Materia Medica", Oriental Classics; Zhan pi value, seven decimal places; Overlooking the Silk Road, developing the economy; End blue and white porcelain, famous overseas.

The development of science and technology is the road to a strong country, and the development of science and technology is the first driving force for the progress of the Chinese nation. Without technology, where would we have a comfortable material life and spiritual enjoyment? Without the advancement of science and technology, how can we eat Hybrid No. 2?

How can we wear cotton clothes, how can we live in high-rise buildings?

Q: Is there a big benefit or a disadvantage to the development of science and technology? Needless to say, of course, it's a big benefit! How do you explain that?

No need to explain! The 8,000-year-old history of Chinese civilization is ironclad evidence, history is changing all the time, and technology is developing all the time. Human beings have learned to use or cook food from the primitive life of drinking blood, from relying on nature to breeding and breeding, from being defenseless to metallurgical smelting, isn't this all progress, isn't this all development?

If the disadvantages outweigh the advantages, then why do human beings still choose to progress? Only progress can make tomorrow better.

The advantages outweigh the disadvantages, and it should be beneficial to enclose the lake and create fields. For youdou China, the population is large and there is a lack of arable land. To a certain extent, the area of cultivated land can be increased and the problem of people's food can be solved.

A large amount of land reclamation from lakes can easily cause flooding disasters and affect water quality.

In the middle reaches of the Yangtze River, a large number of lakes have been enclosed for farmland, and the area of Dongting Lake has declined rapidly from the original largest freshwater lake. Other freshwater lakes are also rapidly decreasing in size, and some have disappeared altogether. These lakes play a role in water conservancy to receive the flood of the Yangtze River, and the reduction of the lake area directly leads to the lack of space for the diversion of the Yangtze River water, which can easily cause flooding.

The floods of '98 also had something to do with this

You have to debate from the environment and life, production, this area is a bit large, now the arable land is decreasing, either building or business, people can't experience the local customs, on the contrary, now in the big cities there are fewer places for people to move, there are fewer beautiful customs, and there is no place for activities and space for release under the huge pressure of going to work, you will go deep from these aspects, I think, this is very easy to answer, find a large article of opposite arguments on the Internet,

It's a disruption of the natural balance. Nature's land use cannot be changed lightly. It takes a long time. The result of man-made change is often punished by nature.
