The colorful biological world can be considered from the following aspects to find information: 1. Fun (few people have heard or seen biological anecdotes, the best of creatures, bionics, etc.); 2. Diversity (there are many kinds of organisms, let's go find some rare and strange creatures); 3. Knowledge (there is a lot of knowledge related to biology, cloning, genetically modified, Ruan virus, IVF, etc., let's screen some of them).
As far as hand-copied newspapers are concerned, you should be pretty much enough to look up these materials. There is no end to learning, I wish you progress in your learning!

It is to write the names of plants and animals and introduce them.

1. Genetic diversity, genetic diversity is an important part of biodiversity. Genetic diversity, in a broad sense, refers to the sum total of the various genetic information carried by organisms on Earth. This genetic information is stored in the genes of an organism.
2. Species diversity, species diversity refers to the richness of animals, plants, microorganisms and other biological species on the earth. Species diversity includes two aspects, one is the richness of species in a certain area, which can be called regional species diversity; The second refers to the degree of uniformity in the distribution of species in terms of ecology, which can be referred to as ecological diversity or community species diversity.
3. Ecosystem diversity, the ecosystem is a natural complex composed of various organisms and their surrounding environment. All species are part of ecosystems. In the ecosystem, not only are species interdependent and mutually restrictive, but also organisms interact with various environmental factors around them.

1. Awareness of biodiversity.
Biodiversity refers to the diversity of life in all forms, levels and complexes of living things on Earth. Simply put, biodiversity is the total diversity and variability of organisms and the systems they are composed of. There are three levels of biodiversity:
Genetic diversity, species diversity, and ecosystem diversity. Biological invasion refers to the entry of foreign organisms into another area, because there are no natural predators in this area, they will reproduce more quickly and form populations, upsetting the balance of the local ecosystem and posing a threat to the survival of native species. Biological invasions are the destruction of biodiversity.
Biodiversity is the result of billions of years of development and evolution of life on earth, and is the material basis for the survival and sustainable development of human beings. It provides all human food and important industrial raw materials such as wood, fiber, oil, and rubber. The vast majority of traditional Chinese medicine comes from biology, and up to now, more than 30,000 organisms have been directly and indirectly used in medicine.
It can be said that the protection of biodiversity is equivalent to protecting the cornerstone of human survival and social development, protecting the foundation of human cultural diversity, and protecting human beings themselves.
Introduction to the International Day for Biological Diversity.
Biodiversity is the result of billions of years of development and evolution of life on earth, and is the material basis for human survival. In order to protect global biodiversity, 153 countries signed the Convention on Biological Diversity at the United Nations Conference on Environment and Development held in Rio de Janeiro, the then capital of Brazil, in 1992. In December 1994, the United Nations General Assembly adopted a resolution designating December 29 as the "International Day for Biological Diversity" to raise awareness of the importance of biodiversity conservation.
On 17 May 2001, in accordance with Resolution 201 of the 55th session of the United Nations General Assembly, the International Day for Biological Diversity was changed to 22 May of each year.

<> the Butterfly Spring in Dali, it is a famous natural attraction. In late spring, when the butterfly flowers are in full bloom, thousands of butterflies will be attracted to lay eggs here, forming a spectacular butterfly spectacle. In recent years, however, this spectacular memory has been lost due to the severe damage to the ecology around the Butterfly Spring.
Factory exhaust gases and wastewater, rural pesticides, and stalls in the park have all destroyed this quiet and beautiful habitat of butterflies to varying degrees, and some people have caught a large number of butterflies for profit, resulting in a sharp decline in butterflies, and the butterfly spring has lost its former glory, which is really regrettable. In addition to regretting, I can't help but think, if the little butterflies have fallen here, what will happen to other creatures? If we don't stop it, we will lose all our diversity!
The conservation of biodiversity and the sustainable use of biological resources are of immeasurable significance to human beings and to the whole world. <>
Human beings can protect biological diversity in the first place, so that many rare animals and plants will not be wiped out. Due to destructive human development, the world's jungles are disappearing at a rate of 20 square meters per minute, and many rare animals and plants are losing their habitats. Taking China as an example, there are more than 10 kinds of animals that have become extinct in China in modern times, such as elk, wild horses, rhinoceros, and high-nosed antelopes, and more than 20 kinds of rare animals such as gibbons, Chinese alligators, wild sika deer, and wild camels are on the verge of extinction.
In terms of plants, there are about 30,000 species of higher plants in China, of which more than 3,000 are on the verge of extinction. In order to protect biodiversity, it is incumbent upon us to create a happy home for these animals and plants. <>
Protecting biodiversity is also important for the conservation of the world's wildlife gene pool. Whether it is crops or poultry and livestock, due to long-term domestication, the ability to resist diseases and pests is extremely low, and once it encounters diseases, it will cause a large number of animal and plant deaths. For example, the nematode disease of soybeans in the United States and the black rot of potatoes in Scotland in history have brought huge economic losses to the country, and the United Kingdom also lost $30 billion when mad cow disease was rampant.
Wild animals, on the other hand, are highly resistant to pests and diseases due to long-term natural selection. In this way, we can use hybrid technology to obtain crops with strong resistance to pests and diseases and high yields, and create greater economic benefits for agricultural production. It is because of the conservation of biodiversity that we can improve our wildlife gene pool.
Protecting biodiversity also protects organisms of important scientific value. There are many plants and animals in the world, providing convincing evidence for the theory of evolution. Conservation of biodiversity makes it possible to make full use of economically important flora and fauna. <>
The protection of biodiversity is of so great significance, so each of us loves the precious resources of the motherland, makes peace with the flora and fauna of the homeland, and resolutely fights against the destruction of biodiversity. Let us all take action to add a piece of green to nature, contribute to the protection of wild animals, let the butterflies flutter in the Butterfly Spring, let the rich and colorful creatures on the earth thrive, and become a sustainable resource for human beings. <>

Disaster prevention and mitigation to defend the homelandDisasters are the natural enemies of people, and they not only cause huge property damage to people, but also deprive tens of thousands of compatriots of their lives. Drought is one of the major natural disasters. With the economic development and population expansion of human beings, the phenomenon of water shortage is becoming more and more serious, which has directly led to the expansion of arid areas and the aggravation of aridification, and the trend of aridification has become a global concern. >>>More
