But knowing the relationship between nature and man does not mean that we are fully aware of the relationship between animals and ecology. From this derives the relationship between animals, ecology and humans. Many people only know that natural disasters such as mudslides and sandstorms can occur without trees and grass, but they do not know that the seeds of many plants were originally sown by birds and animals.

In a book called "Birds and Nature", it is said that some plants can only grow by excreting their seeds in the soil after the bird eats its fruit. If all the birds die, the plant will die out with it.

The same is true for wild animals, many people see wild animals grazing there, but they don't know that the vitality of life lies in renewal, and if it weren't for the way wild animals eat grass, like herders cut alfalfa to help renew the generation, the grass would age and die.

It can be seen that the Creator's miraculous work is to maintain the existence and evolution of our earth with balance. Balance, these two very common words, govern everything in the universe.

If a person's bodily functions are out of balance, he will get sick or even die.

If the ecology of one place is out of balance, other places will taste the bitter fruit;

If the entire ecology is out of balance, the overall living environment of human beings will deteriorate ......

People have gradually realized that humans are not the masters of the earth, and that wild animals, like humans, are part of the biological chain and have the right to live. Cruelty to wild animals is to disregard life, and to protect wild animals is to protect our ecological environment and protect human beings. Therefore, caring for wild animals and promoting people's kindness is to reflect human beings' concern for their own survival and development in a deeper sense, improve the situation of animals, and improve human beings.

This is not only a matter of concept, but also an inevitable requirement of social progress, which reflects the degree of civilization of a country. Because of this, in Germany, the United Kingdom, India, the Philippines and other countries, not to mention the killing of wild animals, even ordinary animals that have been emotionally abused, will be prosecuted by law.

In this regard, we are clearly lagging behind. Although we already have some provisions prohibiting the killing of wild animals, there is still a lack of detailed and detailed provisions. In this regard, Yang Lixin, a professor at Chinese University of China, believes that a personality system should be established, just as people have personalities, animals also have personalities, and according to different personalities to determine the different status of animals in law, and determine different legal protection methods, especially for wild animals.

For ordinary animals that provide services to humans, we should also respect them and treat them well.

This is undoubtedly a good piece of advice, and it provides an effective idea from a legal point of view on how to change people's treatment of animals. I just look forward to the transformation of this idea as soon as possible, because I recently saw a news that due to human and other reasons, the population of the Ili pika, which is only available in China, has decreased sharply and is facing endangerment, and has been listed on the red list of Chinese species.

To put it simply, there are more people, fewer animals, !

If a person's bodily functions are out of balance, he will get sick or even die.

Animals are good friends of humans.

Animals are the same as us.

1 Cloning technology and genetic breeding.

In agriculture, people have used the "cloning" technology to breed a large number of high-quality and high-yielding varieties that are resistant to drought, lodging, and diseases and pests, thus greatly increasing grain production. In this regard, China has entered the forefront of the world's most advanced technology.

2 Cloning technology and protection of endangered organisms.

Cloning technology is a boon for the protection of species, especially rare and endangered species, and has great application prospects. From a biological point of view, this is also one of the most valuable aspects of cloning technology.

3 Cloning Technology and Medicine.

In modern times, doctors are able to perform transplants on almost all human organs and tissues. But in terms of science and technology, rejection in organ transplantation is still the biggest headache. The cause of rejection is poor compatibility due to tissue mismatch.

If the organs of the "cloned" human are provided to the "original human" for organ transplantation, there is absolutely no fear of rejection, because the genes and tissues of the two are also compatible. The question is, is it humane to use "human clons" as organ donors? Is it legal?

Is it economical?

Cloning technology can also be used to reproduce valuable genes in large quantities, for example, in medicine, it is through "cloning" technology that people produce ** diabetes insulin, dwarfism patients regrow growth hormone and dry flexin can resist a variety of viral infections, and so on.

Animals cloned at present include sheep, cows, horses, etc.

By combining cloning technology with other scientific and technological achievements, people can cultivate new varieties of grain and vegetables with high quality and high yield according to their needs. It can also breed a large number of high-quality livestock, which greatly improves the feeding efficiency.

Cloning technology can also save some endangered species and save some endangered animals from doom, thereby regulating the ecological balance of nature. People use cloning technology to cultivate human body ** for skin grafting surgery; It can "manufacture" human body "accessories" such as ears, cartilage, liver, and heart, and can be reassembled once the patient needs ......

【Phoenix Song Luan Dance】Sacred bird song and dance. A metaphor for a wonderful song and dance.

Luan Song and Phoenix Dance] is a metaphor for beautiful songs and dances.

The yellow warbler is singing, and the little swallow is flying. Describe the noisy and active scene of birds in spring. It is often used as a metaphor for the vigorous and prosperous scene of revolution and construction.

Warbler song and butterfly dance] warbler cries like a song, and butterflies fly like a dance. Describe the bright spring and the joy of all things. It is also a metaphor for the good situation. Same as "Song of the Bird and Dance of the Swallow".
