Dalian's "Snake Island" covers an area of ​​less than one square kilometer, but there are 20,000 poisonous snakes hidden in it, where do they come from?

With improvement of people's living standards, people are starting to pay more attention to earth, nature and ecology in addition to their own development. Nowadays, people are paying more attention to various aspects of earth This resource has already been exhausted, but it is also inevitable a consequence of rapid development of industry and rapid development of science and technology since development of man.

Fortunately, humans have limitless wisdom. Although advanced scientific and technological advances have destroyed our former homeland to a certain extent, it is not too late to make up for it. Technology can also use its high development to help us realize protection and restoration of nature.

People have failed to fully understand nature. In this process, human steps never stopped and we moved forward. We explored nature and were grateful to nature. In process of admiring nature, We gradually learned law of coexistence with nature itself and all living things in nature.

Among them, we have paid a huge price. From ancient times to present day, countless animals have died out as a result of natural selection, and advent of man has increased this process by more than a hundred times, especially in 1990s. After industrial revolution of 19th century, this process continued to accelerate.

The damage that people have done to nature and living beings has now, in turn, been repaired by themselves. Rainforests have been destroyed, global warming has occurred, icebergs have melted, sea levels have risen, and countless cities have been destroyed. flooded.

Shortage of water resources, drought attacking man, air pollution, raging sand and dust, blue skies and starry skies are no longer visible in city, this is what we are seeing now, and current actions are specifically for our children and these grandchildren will not be disturbed.

China has now implemented a dual carbon policy. It is expected to peak carbon emissions in 2030 and carbon neutral in 2060. It should also give bright blue skies to our future generations. The country has also introduced many policies and people are paying more and more attention to environment, animals and plants in their daily lives.

In the process of this protection, we cannot make a choice. The appearance of each species has its own inevitable reason for its existence, and this is an integral part of this ecological protection. For example, many dangerous but common animals such as snakes should also be treated with a defensive attitude.

At present, in many rural areas, with exception of hibernation of snakes, snakes are very common in other three seasons of year. Growing up in countryside, I wasn't too afraid of snakes. Feelings, human fear often comes from unknown.

But in many cases we don't have ability to understand, so this situation is created. Under normal circumstances, snakes are often seen in rural areas, and few people want to harm snakes, Since snakes are animals that do not actively attack people, keeping them at a respectful distance and not interfering with each other is best way to survive.

However, snake is an animal that really frightens with feelings. Whether it's in movies, TV shows, or mythological works, snakes are representatives of a fearsome and evil species.

There are more than 200 snake species in China, which is about one tenth of total number of snake species in world, and about a quarter of them are poisonous snakes, that is, it is said that there are more than 50 poisonous snake bells in China, which considered a huge number.

In many films, for example some adventure films about ancient tombs, there are often many shots of venomous snakes entangled, which may be due to long and shiny body of venomous snakes. Poisonous snakes entangled together are always an abnormal horror,< strong>And among several well-known scenic spots in our country is Serpent Island, famous in first battle because of poisonous snakes.

There are many snake islands in my country, such as Lugu Lake Serpent Island, Qiandao Lake Serpent Island, Fairy Lake Serpent Island, and Nanwan Reservoir Serpent Island. Today, I want to introduce you to a very famous snake island in my hometown of Liaoning, Dalian Snake Island.

Snake Island in Dalian is very small. The island is 1,500 meters long and 800 meters wide. In such a small area, various types of snakes live, and total number can reach more than 20,000 individuals. The most famous in Dalian Snake Island is black-browed viper, also known as Snake Viper, which is a unique species in world, so importance of protecting Dalian Snake Island is very high.

The origin of Serpent Island is caused by movement of earth's crust. The movement of plate caused current provinces of Liaoning and Shandong to collide with each other across sea. The original median plain became current Bohai Sea and Yellow Sea. The movement also caused many underwater plates to protrude, forming small islands, including current Dalian Snake Island.

Due to small area, resources that animals and plants can survive are also very limited. Over time, those animals and plants that are not hard enough to survive are mostly extinct, and rest are very resistant. Hungry snakes, especially vipers.

There are no natural enemies on island itself, and vipers have a strong reproductive capacity, so number of snakes on island grows larger and larger until there are over 20,000, reaching a near-balanced number. And principle of survival of fittest has also led to surviving vipers becoming more and more poisonous.

But regardless of whether it is highly poisonous or not, people should equally protect it. After all, small venomous snake is still very fragile in the face of extremely advanced human technology, behind it is a creation of truly incomparable strength.
