Conservation of biological diversity (type)

Our topic today is biology, and creatures can think of the following questions:

Do you have some small creatures at home?

Are you worried about the safety of your little creatures?

If so, would you ever think about bullying or abusing other small creatures?

Do you know how much creature you hurt when you were a child?

Maybe you didn't think of their pain when you hurt them, but when you learn more knowledge, you will find that biology is important to us, indispensable, because we have already integrated into it, we are also creatures, It is also a kind of animal.

Life is important to everyone. Political teachers should hand over to you: If you have a conflict with others, you should learn to think differently, think about why there is a contradiction, what do you say is wrong for others, think if he said it to you or What do you think about this? If everyone learns to think differently, everyone can be like a loved one. If you use this mentality to face the creature you are about to hurt, maybe you will stop the clenched fist and stop the long legs. This way life can continue.

In this realistic society, human beings are increasingly dependent on natural resources. Many of the light animals are extinct in the hands of human beings. In Beijing, there is an extinct animal memorial hall, which is densely lined with various animals. Why is that?

First, human over-exploitation of land has reduced the habitat of animals and plants.

The term habitat is no stranger to people, it is the place where the creature is suitable for survival. Because of the development of people's land resources, the habitat of living things has gradually decreased. I want to think of a national treasure-protected animal like a panda. People have never thought about killing it, but why is it endangered? The problem lies in habitat. The living fossil giant panda, which has survived for a long time in the bamboo forest of Sichuan, is declining in the event of habitat destruction. So far, after people have protected and established protected areas, the number of pandas has reached 2,500 to 3,000.

Next is the food.

When it comes to food, it will remind you of the food chain. One of the most familiar words: big fish eat small fish and small fish to eat shrimp. This is a food chain. The dependence of living things on food is very strong. Most of the energy of food comes from food. If there is no food, the creature will die because there is no food, and even be extinct! ! ! The biology teacher said: Creatures are interdependent, and perhaps one less will bring a biological change to the whole earth. Let's take the food chain that everyone is familiar with.

Eagle→snake→frog→worm→plant

Think about it, what if there is no plant? What does the worm eat? The worm is only hungry. What if there is no insect? The frog will be hungry. By analogy, it can be imagined. Everyone may think, if there is no eagle? Isn't the snake invincible? Yes, the snake will live a carefree life, don't cheer the snake first, the scary place of the snake has just begun! The snake will breed freely. Without the obstruction of natural enemies, it can be said that it is High, and the number is rising sharply. This will be the end of the frog, but the resistance of the snake will be reduced, and some organizations will degenerate without natural enemies. What you get is the "aggression" of microorganisms! The sooner you die!

Readers may think of a question: In the habitat, isn't it meant to protect animals? But why is it that food is threatening other creatures by relying on food?

I am here to tell you that for humans, only the species of wild animals are protected. Poultry is no exception, but poultry is your own and has its own rights. However, there are many species of poultry, such as domestic pigs, ducks, and ducks. You can eat them. If you want to eat wild ducks, you should ask the National Animal Protection Association. . . The country lets you protect wildlife, and I have summed it up myself:

1. It is to protect the survival of wild animals.

2. It may also be a concern about whether these creatures are fluent or not.

Therefore, biology is our partner, and we protect them as we protect ourselves.

Cherish life, start with me! Start small things and start from the front of the creature!
