Owls sleep in the street.
I went downstairs to rest and found an owl curled up in the corner. I think it's strange.
I frowned and asked, "Brother Owl, what are you doing here without going to rest?" I have to catch mice at night! "
The owl looked up at me and said sadly, "This used to be a dense forest and a paradise for our birds. The river is crystal clear and the trees are towering into the sky. But when humans came here, they cut down a lot of trees and seriously polluted the rivers. Many factories and buildings have been built here. Let us really don't know where to go! "
It is said that this is not the first time! I think Bailing's sister and starling's brother have similar experiences.
Poor owl. We are too selfish to make birds homeless for a better life, regardless of their feelings.
Reconnaissance report 2
The tragedy happened again.
I was just about to take off when the fog blinded my eyes and I stopped again.
As soon as I turned around, I saw that the owl had vomited blood and stood up, and fell to the ground and died.
I suddenly blindsided: "What's the matter! ? "
The sparrow whimpered and said, "It, it, it hasn't eaten for several days. When it saw a mouse die in front of it, it wolfed it down ... "
"What's the problem with that?" I'm confused.
"That mouse ate rat poison!" The little sparrow cried even harder. "Uh-huh, wow ..."
Alas, it's really wrong for such a thing to happen. Originally, drugs were used to eliminate "harm", but even our beneficial bird friends were implicated.
Isn't that enough to make birds homeless? Why must we "kill them all"?
Reconnaissance report 3-
The demise of Sharon rabbit
How strange! Where is Sharon Rabbit? Only a piece of yellow sand answered me, "They are in a small puddle that has just rained not far ahead." I flew in a hurry and saw Sharon rabbits being kept in cages.
I asked with concern, "Why didn't you resist? Let humans put you in a cage? "
"It rains once a year here, and our leaders lead us to drink water. I didn't expect it to be a trap set by human beings. After we drank ... "
"Are you okay! Wake up! "
According to the old man, the fur of Sharon rabbits is rare and precious, and it rains once a year where they live. According to this feature, the merchant assumed the water source and caught Sharon rabbit. Such tragedies have been staged again and again, and Sharon rabbit has become extinct!
Human beings are selfish, eager for quick success and instant benefit, and harm others and themselves. Our animal friends are gradually decreasing and dying, the ecological balance is being destroyed day by day, and the home we live in is becoming more and more pitiful. Dear human friends: protect nature and care for life! Do you need it?

The blue whale is bleeding
Oh, how did this sea area turn red? Search ahead, the original blue whale is bleeding! Hey, what about the blue whale?
What is missing a fin? A whaling ship not far away told me the answer: the blue whale gave up to avoid killing.
Abandoned the fin. Man, will you die if you torture an animal less?
It really hurts to read the bird reconnaissance report. At the same time, I also appeal to all mankind: the animal is me.

The ninth answer: the daughter of a colleague answered.
What's the point?
When my little girl was two years old (at that time, she only knew numbers within twenty), I held out an index finger in each hand. Leaned over and asked her, "Baby, what's one plus one?" She said loudly, "1 1". (I'm dizzy)
The quantity is far beyond my expectation ~
1+ 1= 1 indicates that a father and a mother gave birth to a baby.
1+ 1 = 3 A father and a mother became a family of three after giving birth to a baby.
1+ 1 = 4 A father and a mother gave birth to twins and became a family of four.
Goldbach is a German middle school teacher and a famous mathematician. He was born in 1690, and was elected as an academician of Russian Academy of Sciences in 1725. 1742, Goldbach found in teaching that every even number not less than 6 is the sum of two prime numbers (numbers that can only be divisible by themselves). For example, 6 = 3+3, 12 = 5+7 and so on. 1742 on June 7, Goldbach wrote to the great mathematician Euler at that time, and put forward the following conjecture:
(a) Any > even number =6 can be expressed as the sum of two odd prime numbers.
(b) Any odd number > 9 can be expressed as the sum of three odd prime numbers.
This is the famous Goldbach conjecture. In his reply to him on June 30th, Euler said that he thought this conjecture was correct, but he could not prove it. Describing such a simple problem, even a top mathematician like Euler can't prove it. This conjecture has attracted the attention of many mathematicians. Since Goldbach put forward this conjecture, many mathematicians have been trying to conquer it, but they have not succeeded. Of course, some people have done some specific verification work, such as: 6 = 3+3, 8 = 3+5, 10 = 5+5 = 3+7, 12 = 5+7,14 = 7+7 = 3+/kloc. Someone checked the even numbers within 33× 108 and above 6 one by one, and Goldbach conjecture (a) was established. But strict mathematical proof requires the efforts of mathematicians.
Since then, this famous mathematical problem has attracted the attention of thousands of mathematicians all over the world. 200 years have passed and no one has proved it. Goldbach conjecture has therefore become an unattainable "pearl" in the crown of mathematics. People's enthusiasm for Goldbach conjecture lasted for more than 200 years. Many mathematicians in the world try their best, but they still can't figure it out.
It was not until the 1920s that people began to approach it. 1920, the Norwegian mathematician Brown proved by an ancient screening method, and reached a conclusion that every even number with a large ratio can be expressed as (99). This method of narrowing the encirclement is very effective, so scientists gradually reduce the prime factor in each number from (99) until each number is a prime number, thus proving Goldbach's conjecture.
At present, the best result is proved by China mathematician Chen Jingrun in 1966, which is called Chen Theorem: "Any large enough even number is the sum of a prime number and a natural number, while the latter is only the product of two prime numbers." This result is often called a big even number and can be expressed as "1+2".
Before Chen Jingrun, the progress of even numbers can be expressed as the sum of the products of S prime numbers and T prime numbers (referred to as the "s+t" problem) as follows:
1920, Norway Brown proved "9+9".
1924, Latmach of Germany proved "7+7".
1932, Esterman proved "6+6".
1937, Lacey in Italy successively proved "5+7", "4+9", "3+ 15" and "2+366".
1938, Bukit Tiber of the Soviet Union proved "5+5".
1940, Bukit Tiber of the Soviet Union proved "4+4".
1948, Rini of Hungary proved "1+c", where c is a large natural number.
1956, Wang Yuan of China proved "3+4".
1957, China and Wang Yuan successively proved "3+3" and "2+3".
1962, Pan Chengdong of China and Barba of the Soviet Union proved "1+5", and Wang Yuan of China proved "1+4".
1965, Buchwitz Taber and vinogradov Jr. of the Soviet Union and Pemberley of Italy proved "1+3".
1966, China Chen Jingrun proved "1+2".
It took 46 years from Brown's proof of 1920 of "9+9" to Chen Jingrun's capture of 1966 of "+2". Since the birth of Chen Theorem for 30 years, it is futile for people to further study Goldbach conjecture.
The idea of Brownian screening method is as follows: any even number (natural number) can be written as 2n, where n is a natural number, and 2n can be expressed as the sum of a pair of natural numbers in n different forms: 2n =1+(2n-1) = 2+(2n-2) = 3+(2n-3) = 2i and 2i. 3j and (2n-3j), j = 2, 3, ...; And so on), if it can be proved that at least one pair of natural numbers is not filtered out, such as p 1 and p2, then both p 1 and p2 are prime numbers, that is, n=p 1+p2, then Goldbach's conjecture is proved. The description in the previous part is a natural idea. The key is to prove that' at least one pair of natural numbers has not been filtered out'. No one in the world can prove this part yet. If it can be proved, this conjecture will be solved.
However, because the big even number n (not less than 6) is equal to the sum of odd numbers of its corresponding odd number series (starting with 3 and ending with n-3). Therefore, according to the sum of odd numbers, prime+prime (1+ kloc-0/) or prime+composite (1+2) (including composite+prime 2+ 1 or composite+composite 2+2) (Note:/kloc) That is, the occurrence "category combination" of 1+ 1 or 1+2 can be derived as 1+ 1 and 1+2. Because 1+2 and 2+2 and 1+2 do not contain1+. So 1+ 1 does not cover all possible "category combinations", that is, its existence is alternating. So far, if the existence of 1+2 and 1+2 can be excluded, it is proved that 1+ 1 But the fact is that 1+2 and 2+2, and 1+2 (or at least one of them) are some laws revealed by Chen's theorem (any large enough even number can be expressed as the sum of two prime numbers, or the sum of the products of one prime number and two prime numbers), such as the existence of 1+2 and the coexistence of 6542. Therefore, 1+2 and 2+2, and 1+2 (or at least one) "category combination" patterns are certain, objective and inevitable. So 1+ 1 is impossible. This fully shows that the Brownian sieve method cannot prove "1+ 1".
Because the distribution of prime numbers itself changes in disorder, there is no simple proportional relationship between the change of prime number pairs and the increase of even numbers, and the value of prime number pairs rises and falls when even numbers increase. Can the change of prime pairs be related to the change of even numbers through mathematical relations? Can't! There is no quantitative law to follow in the relationship between even values and their prime pair values. For more than 200 years, people's efforts have proved this point, and finally they choose to give up and find another way. So there are people who prove Goldbach's conjecture in other ways. Their efforts have only made progress in some fields of mathematics, and have no effect on Goldbach's conjecture.
Goldbach conjecture is essentially the relationship between an even number and its prime number pair, and the mathematical expression expressing the relationship between even number and its prime number pair does not exist. It can be proved in practice, but the contradiction between individual even numbers and all even numbers cannot be solved logically. How do individuals equal the average? Individuals and the general are the same in nature, but opposite in quantity. Contradictions will always exist. Goldbach conjecture is a mathematical conclusion that can never be proved theoretically and logically.
