Can you imagine eating one churro every morning and preventing planes around the world from taking off? Can you imagine that driving every day will reduce the number of applause for love? Can you imagine that sleeping at night for a long time without turning off the lights will lead to ** cases?
Don't think it's, it's that serious!
According to the study "When Climate Change Triggers War" by American writer John Wendell, every day when the average temperature exceeds will cause the birth rate to drop 8 to 10 months later. What is this concept?
According to climate change models**, the number of days the average temperature exceeds in the United States has increased from 30 to 90 per year, which has led to a decrease of 100,000 newborns. In other words, the climate is warming, people applaud love less often, and with it, fewer newborns.
Similarly, according to research by the MIT Lab, based on current climate change trends, the number of insomnia days per American per month is expected to increase by 2050, and by 2099, that number will double, with more insomnia days per person per month. In addition, scientists surveyed nearly 60 countries and found that rising temperatures can make people more violent, especially in areas of already conflict and instability.
It is assumed that for every 1 increase in global temperature, the rate will increase by 6.
In addition, according to the research of scientists, it has also been found that: with global warming, sharks are attacking humans more and more; The mouthparts of bees are also getting shorter, making it more difficult for pollen to spread, and many plants only bloom and do not bear fruit, and in the end, it is likely to lead to the extinction of plants, animals, and humans. So, don't underestimate your every move, and don't underestimate this global warming, do it and cherish it.
-
Because humans have destroyed the shark ecological environment, causing many sharks to die due to environmental degradation, the violent nature of sharks will be revealed.
-
This is the revenge of the shark, who is willing to hate humanity and bring disaster upon him.
-
Rising temperatures can make people more violent, especially in areas of already conflict and instability.
-
The weather is hot, which affects the mood of the animal and makes it easier to be irritable.
-
Because of global warming, sharks feel bad.
-
The main thing is that it warms up and then the water warms, and when it gets changed, the shark's temperament will come out.
-
Global temperatures are warming and there is no food to eat. Grumpy.
-
Maybe if it's too hot, sharks will have a temper.

Summary. If the sharks disappear, the number of small fish will soar because there are no predators. Soon, their food, including plankton, microbes, and shrimp, will disappear, and eventually all the small fish will disappear as well.
Why is it said that the drastic decline in shark populations will be a fatal blow to the entire marine biodiversity and optimization.
If the sharks disappear, the population of the small fish will soar because there are no predators. Soon, their delicate food, including plankton, microbes, and shrimp, will disappear, and eventually all the small fish will disappear.
When this happens, algae and bacteria can enter the reef and cover the polyps, preventing them from entering the hall for photosynthesis. The coral will disappear, leaving only the skeleton and eventually turning into limestone. Then, hail creeping starfish, sea urchins and other animals will arrive.
We call them nibbling (or nibbling) animals. So instead of a large group of different species of sharks, bony fish, invertebrates, and mollusks, you end up seeing a coral reef with only 4 to 5 species. In marine food webs, sharks play another important role as food for marine predators.
Sharks can also influence plankton populations by preying on fish and play a role in regulating oxygen production in the ocean.
According to the reading purpose of "Why Sharks Are the Know-it-all Plastic Surgeons of the Lunchi Marine System", you will focus on the first few paragraphs and use concise language after reading; According to why, take a li.
Sharks play an important role in regulating the balance of marine ecosystems.
It can be used to change the size of the eyes and tail fins of many fish in the ocean. In the original text, sharks are called cosmetic surgeons because they can change the size of the eyes and tail fins of many fish in the ocean.
It is also a ferocious fish that eats carnivorous and is known as the "wolf of the sea".
It is the scavenger of the marine system, read in concise language.
Sharks cannot be left in the ocean, and it is the sharks, a special "dust bucket ocean cleaner", that devours those infected fish, which ensures that the "health ruler" of the ocean is sharpened and the vitality of the sea is ensured.
-
Of course, because sharks go extinct, marine life will grow wildly, which will have an impact on the ecology.
-
Because 70% of the Earth's oxygen is provided by phytoplankton in the ocean. Phytoplankton are rich in chlorophyll, which releases large amounts of oxygen when they absorb carbon dioxide from the Earth's atmosphere.
In the marine biological chain, phytoplankton live at the bottom, zooplankton eat phytoplankton, small fish and shrimp eat zooplankton, and fierce big fish eat small fish and shrimp. And if the shark becomes extinct one day, without the control of natural predators, other sea creatures will go crazy eating marine phytoplankton. By then, the earth will not have enough oxygen, but it will be too late.
So at the end of the day, saving sharks is actually saving humanity itself!
-
Sharks only eat small fish, so it should be okay.

Animals with vertebral spine in their bodies are called vertebrates, and animals without vertebral spine in their bodies are called invertebrates a.
b. Soft-shelled turtles belong to reptiles, and there is a spine B error in the body;
c. Squid is a mollusk and has no spine in its body c correct;
d. Whales belong to mammals and have spine d errors in their bodies
Therefore, c
-
The main characteristics of mammals are hairy on the body surface, differentiated teeth, diaphragm in the body cavity, four chambers of the heart, breathing with lungs, developed brain, constant body temperature, viviparity, lactation The scientific name of the "mermaid" is dugong, although it lives in the water and swims, but the mother feeds the larvae, so it belongs to the mammal
Therefore, c
-
The main characteristics of fish are that they live in water all their lives, breathe with gills, swim with fins, and have mostly scales on their body surface Octopuses have soft bodies, mantles, and are mollusks; Whales live in water, but breathe with their lungs, are viviparous, have a constant body temperature, and are therefore mammals Soft-shelled turtles breathe with lungs, have an unconstant body temperature, fertilize in the body, and the eggs hatch naturally, and are reptiles; Seahorses breathe with gills and swim with fins, have the characteristics of fish, and are fishes.
So the answer is: it is the seahorse that can enter the venue. Because octopuses are mollusks, blue whales are mammals, and soft-shelled turtles are reptiles.

Since the end of autumn 2009, heavy snowfall, strong cooling, and cold waves have taken turns, causing the temperature in Beijing and even in North China to drop again and again, and the maximum temperature dropped to January 4, 2010, which is the lowest value of the highest temperature in early January since 1951. From January 2 to 3, 2010, the snowfall at the observatory in the southern suburbs of Beijing reached 10 mm, the largest daily snowfall for the same period since 1951. >>>More
In fact, the question is very simple, everyone knows that ice melts or sublimates to absorb heat! When global warming increases the temperature, the melting of glaciers and icebergs on the earth accelerates, and the melting of glaciers and icebergs needs to take away a large amount of heat, and then through heat transfer and diffusion, the climate of places other than icebergs and icebergs is suddenly cooled! However, the thermal expansion and contraction of the air will not make it cooler in summer, because in summer the temperature is high and the atmospheric pressure is also high, and the apex will flow towards the poles (except in special cases), and in winter, it will shrink towards the equator, and the cold air at the poles will pour in in large quantities! >>>More
