Day by day in the infinite game

Chapter 57 57. Foreign invasion
All beings are equal, and every life should be respected and treated equally.

However, specific analysis of specific issues cannot be generalized.

When it comes to our companion animals, pets or other wild animals, we really should respect their lives and treat them equally.

But what about dangerous invasive alien species?What if it has threatened the safety of local organisms?
Do you still have to hold your neck and talk about respecting life?

Where does that leave the life of native native species?
A perfect ecosystem is formed after a long period of evolution. The species in it gradually become stable after hundreds of thousands of years of competition, rejection, and adaptation, forming an inseparable relationship of interdependence and mutual restriction.

With the increase in human activities and the influence of various factors such as geographical anthropogenic factors, species outside the natural distribution range have appeared in the original natural environment, collectively referred to as alien species.

A long time ago, our ancestors began to explore the world as their lives gradually settled down, and discovered and brought back many novel species that were not found in the native land, such as peppers, which were introduced to our country from the Americas at the end of the 16th century, such as corn, which was introduced to my country in the Ming Dynasty. It was introduced to my country in the 30th year of Jiajing.These species that have adapted to the local environment under the cultivation and improvement of our ancestors and under the care of humans without causing harm to the environment and have created great benefits for agricultural production are called "introduced species" and are part of the exotic species. kind.

If alien species do not adapt to the local environment, they may not be able to survive and have little impact; if they adapt to the environment and lack or have no natural enemies, they will cause harm to local species and affect the ecological balance. This alien species may grow into an "invasive species" ".

For example, apple snails, red ants, crayfish, Canadian goldenrod, American white moth, alligator gar...

Since it is "invading" and foreign, it cannot coexist peacefully and in a friendly way, so it must be severely cracked down and resolutely eliminated.

Tang Qinqin is currently stuck in Obsidian's new title with a frown on his face.

No matter how bitter and hateful its owner is, Obsidian is so happy - look at its trembling legs and the narrow-mindedness flashing in its eyes from time to time.

"Procambarus clarkii, or crayfish, as one of the representatives of invasive species, has always made us as foodies love and hate it. What we love is naturally its deliciousness, rich in protein and easy to absorb nutrients, but what we hate is There are all kinds of rumors about it.”

"Rumor [-]: What exactly are crayfish? They were once mistaken for bugs because of their weird appearance. In fact, they are a type of freshwater crayfish originating from North America, belonging to the family Decapodidae."

"Rumor [-]: Crayfish live in sewage, eat garbage, have excessive levels of heavy metals in their bodies, and have parasites."

Tang Qinqin turned to the answer and then read: "Crayfish are actually relatively adaptable to the environment. They can survive in harsh sewage environments, but they grow slowly and affect reproduction. But it does not mean that they can only live in sewage."

"As a big lobster-eating country, our food needs rely solely on catching crayfish that survive in the wild. It is not enough to fill our teeth. Most of the crayfish we usually eat are artificially cultured. In order to increase production, we feed them green The feed and water quality are also clean and hygienic.”

"Shedding the crayfish's shell will remove heavy metals from the body."

"Crayfish living in fresh water are more likely to have parasites. However, if you don't eat crayfish that have not been cooked at high temperatures and pay attention to disinfecting utensils, you don't have to worry too much about parasites."

"Then I'd better eat prawns."

As a northern coastal person, Tang Qinqin has been accustomed to eating fish, shrimps and crabs from the sea since he was a child. Tang Qinqin, who has almost no knowledge of crayfish, which is praised by everyone as a favorite and its various ways to eat it, was dumbfounded throughout the whole process. In the end, he completely followed the instructions Read the answer in full.

Tang Qinqin: It’s my fault that I don’t study well. This question is out of line.

"According to statistics, species invasion is mostly through artificial introduction. For example, there are more red fire ants in the south, which are extremely destructive. They feed on crop roots, seeds, fruits, etc., causing damage to crops, causing great economic losses, and even It will damage public facilities and communication systems, and it will bite people and animals. The venom will cause a burning sensation in the wound, and severe cases can lead to shock and death."

"Man-made introduction? It should be the result of some people who like to keep strange pets that are unique to foreign countries, and then abandon them for various reasons or run them into the wild without natural enemies and in a suitable environment."

More and more people like to keep different pets, such as alligator gar, scavengers, African giant snails, snapping turtles, etc.

The first two have caused great damage to the ecological environment of water in many places. Where they exist, almost no other fish can survive.

There are also many types of invasive species in plants, such as the Canadian goldenrod known as the crazy hundred-root grass, the crazy destroying grass-Eupatorium adenophora, the crazy aquatic flower-water hyacinth...

Just by listening to their nicknames, you can guess how scary they are.

"Isn't it? Come again?"

Tang Qinqin, who was good at complementing the biological characteristics of various invasive species, looked confused when he heard the mechanical sound.

"Ding! The player triggers the game mission [Crazy Invasive Species]. The difficulty of this game is Hard++. The game rules are different from the past. Players are requested to read the game rules carefully."

"The rules of this quiz game are as follows:
1. Players need to correctly distinguish between invasive alien species and local species. During the game, players who mistakenly harm local species will be punished;

2. Various methods can be used to eliminate invasive species, but the ecological environment must not be damaged, and offenders will be punished;
3. Take remedial measures to the ecological environment that has been damaged by invasive species;
4. Start with yourself, correctly understand ecological civilization, and protect the natural environment.

5. Eliminate different invasive species and receive rewards based on their different levels of harm. "

Tang Qinqin: The first rule of the game is for me.

Tang Qinqin: Looking through the information to make up for it...

I took the time to send messages to my friends.I don't forget my conscience and suggest that everyone just hold on to the Buddha's feet for the time being.

Listening to the "punishment" in the game rules, it feels a bit unusual.

After staying up for a day, I simply went through the information about invasive species that can be found on the Internet.

I can’t remember anything else, but at least I have to know what it looks like, and I probably have some idea of ​​my living habits.

After I felt about the same, I simply ate some tomato and egg noodles, then washed up and went to bed early.

At five o'clock the next morning, Tang Qinqin got up, packed up, ate some wontons, and then entered the game.

Another unique feature of this round of the game is that there is a game map.

The game map is covered with dense light spots of various colors. Look carefully at the markings in the blank space next to it. The light spots represent the location of invasive species. Press the light spot and you will be transported to the corresponding place. Different colors represent different degrees of harm.

Red is extremely dangerous.

Orange is very dangerous.

Yellow is general hazard.

Blue indicates mild danger.

Being rated as extremely dangerous means that this invasive species has caused great damage to the ecological environment, has a wide range, and seriously threatens the ecological balance. The situation is urgent, so Tang Qinqin did not hesitate and chose one of the red light spots and pressed it.
