The construction of the US-Mexico border wall is expected to be about 1,600 kilometers long, and the basic cost is about 25 billion US dollars, so the construction of a 50-kilometer-long separation wall between the east and west of the East China Sea Island will cost more than 5 billion US dollars, because the US-Mexico border wall only needs to isolate people from climbing from one side of the wall to the other, and the separation wall between the east and west of the East China Sea Island must isolate the huge goose-headed dragon, the intelligent swift dragon, and other giant beasts, and dangerous predators, the height of the wall must be at least 15 to 20 meters, the thickness must be at least 1 meter, and the wall must be extended into the sea to prevent intelligent predators from the sea'Smuggling' to the East Island and preying on humans.

Unless Chen Yan exterminates the creatures on the East China Sea Island, then Chen Yan will not have to spend $5 billion to build a wall.

……

Chen Yan sat on an island and reef fishing, swiping his mobile phone.

Chen Yan suddenly saw a piece of news.

This is a news story reported by The Times, which is a major newspaper and has always been regarded as the first mainstream newspaper in the United Kingdom, known as "the faithful recorder of British society", and the authenticity is more authoritative.

"Because Chen Yan filled 146 islands in the ocean, filling in the total volume of 120 million cubic meters of the ocean, resulting in a global sea level rise of 3cm, as a comparison, from 2000 to 2009, the annual rate of global sea level rise was 3 mm, affected by this, the coastal erosion range of coastal countries around the world increased, seawater intrusion and soil salinization were serious, and saltwater invaded the soil, affecting the groundwater freshwater veins.

It is estimated that rising sea levels have also exacerbated storm surge disasters in coastal areas around the world, affecting the livelihoods and economic development of people in the affected areas, and it is estimated that the global economic losses caused by a 3 cm rise in sea levels will reach US$2 billion. China and Chen Yan are responsible.

It has attracted the attention of the whole world.

Chen Yan checked the data and found that sea level rise is a slow-onset natural disaster for human survival and economic development.

It is an indisputable fact that climate change is causing sea levels to rise.

In particular, the carbon dioxide produced when people incinerate fossil minerals such as coal and oil to generate energy or cut down forests and burn them enters the earth's atmosphere, causing the greenhouse effect, as well as the impact of solar activity on the earth's temperature, global warming, melting of polar glaciers, and the expansion of upper seawater.

If all the ice at the poles of the earth melted, the sea level would rise by 70 meters, and most of the world's coastal lowlands and low-altitude countries would be submerged, which is of course unlikely.

Chen Yan took out the bottle, put it in the sea, and filled the bottle with seawater.

Sea levels are falling at a rate that is visible to the naked eye.

The sea level dropped by 3 cm.

The filling of 146 islands into the ocean has raised global sea levels by 3 cm, and it is now flattened.

The rise and fall of sea level by 3 cm is not noticeable to ordinary people, but for scientists who study the rise in sea level caused by global climate change, the sudden drop in sea level by 3 cm is suddenly noticeable.

Many scientists around the world have monitored a sudden drop in sea level of 3 cm, 3.2 cm to be exact, and the 3.2 cm drop was between 17:32 and 17:33 New York time.

How is it possible that the sea level has dropped by 3.2 cm in one minute, which means that the earth's oceans have disappeared by 127 million cubic meters of seawater in one minute.

At this time, many people thought of the mysterious bottle in Chen Yan's hand.

At 17:32 New York time, the sea level dropped by 3 centimeters in an instant, and 127 million cubic meters of seawater that disappeared from the earth's oceans were packed into mysterious bottles.

Coincidentally, in the past few days, international authoritative media, including the British Times, Le Monde, the New York Times, Fox TV, and the Daily News, have reported criticism, accusing China and Chen Yan of filling 146 islands in the ocean, causing the earth's sea level to rise by 3cm,...... It is estimated that the global economic damage caused by a 3cm rise in sea level amounted to $2 billion.

Many people around the world have a picture in their minds.

Chen Yan: Because of China and China, the global sea level has risen by 3 cm, and as a result, coastal erosion has increased in coastal countries around the world, and seawater intrusion and soil salinization have become serious,...... , causing global economic losses of $2 billion, I don't want to, now I let the global sea level drop by 3cm, and now it's flattened, and I still have 2 mm to compensate.

Chen Yan saw the report,...... , the sea level has risen by 3cm, and the coastal erosion of coastal countries around the world has increased,...... , Chen Yan took out the bottle, put it in the sea, and filled the bottle with seawater,...... As a result, the global sea level has dropped by 3.2cm, and the extra 2 mm, Chen Yanke did not measure it with a ruler.

……

On Facebook, AC Nielsen launched an open-ended questionnaire.

Q, if global sea levels drop one day, how much do you want them to fall?

Option 1, drop 19cm. As a result of the Industrial Revolution, the global sea level rose by 19 cm from 1901 to 2010. A map is attached, and the map is almost unchanged.

Option 2, descend 12 meters. After the sea level dropped by 12 meters, the San Francisco Bridge lost its effect, the Golden Gate Strait was exposed to the bottom of the sea, and the territory of the United States increased by 7,600 kilometers. A map is attached, look carefully, many areas of the earth have changed, the Bahamas has become a complete island, most of the long strait of the Strait of Malacca has exposed the seabed, the depth of the Strait of Malacca is only more than 20 meters, most of it is between 5 and 20 meters, and the Strait of Malacca, the world's four major maritime communication arteries, has been completely abandoned.

Option 3, descend 50 meters. Australia is connected with Papua and New Guinea, most of China's Bohai Sea and Yellow Sea have disappeared, Chinese mainland and the west side of the North Korean Peninsula have been connected, and two of the world's four major maritime communication arteries have been abolished, namely the Suez Canal and the Panama Canal.

The Strait of Gibraltar has become very narrow, and the territory of the United States will increase by 570,000 square kilometers, and China's land area will exceed 10 million square kilometers, reaching 11.4 million square kilometers,.....。 A map is attached. It is clear that the map has changed dramatically.

Option 4, descend 100 meters,...... , followed by a map, you can clearly see that many continents, islands, and regions of the world are connected.

Netizens found this questionnaire interesting and full of imagination.

Many netizens participated in the questionnaire.

Facebook has more than 2 billion monthly active users worldwide, with 240 million users participating in surveys.
