CATDOLL : CATDOLL: Why is the number of dolphins in China decreasing?

1. Why is the number of dolphins in China decreasing?

There are three reasons for the decrease in the number of dolphins in China: 1. Construction of water conservancy projects. At present, many places have built dams and flood control projects on many rivers for industrial water or hydropower generation. These projects that seem to have no impact on dolphins actually cause great obstacles to dolphin migration and other activities. A good example is: everyone may have heard of the white-fin dolphin. It was once a national treasure that we were proud of, but the completion of the Three Gorges Dam has more or less accelerated its quiet disappearance. At present, this species of dolphin is equivalent to extinction.

2. Noise pollution

Hearing is the most sensitive organ of dolphins. They use hearing to hunt, swim and play. However, with the advancement of science and technology, various underwater engineering equipment and large and small ships traveling day and night have had a great impact on the hearing of dolphins. There have even been incidents of collisions between ships and dolphins. These man-made noise pollutions have caused physical and mental damage to dolphins, causing them to lose control of their behavior, increase stress and develop abnormal living habits.

3 people hunted

The most abundant thing at sea is the fishing industry, but the accidental catching of dolphins during fishing happens from time to time. Every year, a large number of dolphins are accidentally caught and killed in my country.

2. Has the number of tabby cats in China decreased?

The number of civet cats in China is decreasing. In the past, families kept cats from our country, mostly civet cats. Now that people's living standards have improved, cats are starting to be purebred cats. Because civet cats are more wild than other cat breeds, fewer people keep civet cats. There are more civet cats among stray cats, but the living environment of stray cats is too poor.

3. Chinese fish?

There are 804 species of freshwater fish native to my country, of which 632 species belong to the Cypriniformes order, accounting for 77.2% of the total; followed by 84 species of Siluriformes, accounting for 10.4% of the total; 56 species of Perciformes, accounting for 6.9% of the total; 22 species of Salmoniformes, accounting for 2.7% of the total; and 7 species of Acipenser. There are more than 50 species of major freshwater economic fish that are common and have high production in inland waters, including species unique to my country such as black carp, grass carp, silver carp, bighead carp, etc.

4. What is the reason for the decrease in wild fish in Hainan?

1. Overfishing. For the fish in lakes and rivers, people think that if they are all caught, they will appear again next year, and there is no such thing as leaving any small fish fry. However, this "root-out" fishing method is one of the main culprits that has caused the disappearance of many wild fish.

2. Invasion of alien species. China is one of the countries that suffers the most serious problem of alien species invasion. Many people think that alien species can be eaten, but in fact, many of them are unusable, and it is difficult to deal with them with conventional methods, so they have been causing continuous damage to my country's ecological environment. The reduction of wild fish is one example. These alien species have greatly invaded the territory that originally belonged to native fish, and some of them even feed on native fish. Therefore, it is understandable that the number of wild fish is decreasing.

3. Excessive use of pesticides. In the past, using pesticides on farms was a luxury, but now choosing not to use pesticides on farms is considered an outlier, which shows how popular pesticides are now. However, this popularity is not a good thing for wild fish. In the past, without pesticides, fish in ponds could live without worries. Now people use pesticides on a large scale. Once it rains, the pesticides in the soil will flow into rivers or lakes with rainwater, causing a fatal blow to the survival of wild fish.

2. Enter the command: Enter the command "bot_kick" in the console, it will kick all robots out of the game.

3. Adjust the number of bots: Enter the command "bot_quota [quantity]" and replace [quantity] with the number of bots you want.

4. Save settings: Enter "host_writeconfig" in the console to save your settings. Through the above steps, you can easily reduce the number of human and computer in CSGO and make the game more in line with your expectations.

6. What is the reason for the decline in fish population in the Rhine River?

Mainly water pollution.

50 years ago, the Rhine River was the river with the largest salmon production in Europe, but salmon completely disappeared in 1958. In the early 1950s, the Rhine River was still clear and people could swim and fish in the river.

By the end of the 1950s, the countries in the basin began large-scale post-war reconstruction. A large number of energy, chemical and smelting companies simultaneously demanded industrial water from the Rhine and discharged large amounts of wastewater into the river. The water quality of the Rhine deteriorated sharply. In the 1970s, when the pollution was the most serious, the dissolved oxygen in the river water near the city was almost zero, and the fish completely disappeared. It was called the "sewer of Western Europe."

7. How are Chinese fish classified?

There are more than 3,000 species of fish in my country, including more than 1,000 freshwater fish, 632 species of Cypriniformes, accounting for 77.2% of the total; followed by 84 species of Siluriformes, accounting for 10.4% of the total; 56 species of Perciformes, accounting for 6.9% of the total; 22 species of Salmoniformes, accounting for 2.7% of the total; and 7 species of Sturgeons.

my country's fish are mainly distributed in the East China Sea, South China Sea, Bohai Sea, Yangtze River, Yellow River, Pearl River and other river basins across the country.

8. How can companies reduce the amount of external financing?

Spontaneous growth of enterprises can reduce the amount of external financing

Spontaneously growing liabilities are generally generated by operating activities, such as accounts payable, wages payable, and other payables.

For example, the company used to pay for goods in cash and had no accounts payable. Now, it has a 3-month payment period with suppliers, so accounts payable are generated. Since the supplier is not paid immediately after the goods are purchased, the cash saved can be used for other things, thus reducing the amount of external financing from the company.

9. Can the number of seats in buses be reduced?

No, the number of seats in a bus is set at the factory. It is illegal to modify and reduce the number of seats at will.

10. How can forests reduce the number of wild people?

How to count the number of wild people in the forest

If you feel there are too many wild men in the forest, you can build custom walls, houses, traps and statues in the manual. Statues can reduce the number of wild men coming, and houses and walls can effectively resist wild men and lure them into traps.
