Why can t pest animals be completely eradicated

Excessive extermination of pest animals can disrupt the balanced development of ecosystems. Everything has its natural enemies, and if all the harmful animals are eliminated, then the animals that feed on these harmful animals will be starved of food.

There is no absolute good or bad in anything, and like you said about harmful animals, it also has a beneficial side. Moreover, if it is really eliminated, it will upset the ecological balance and bring ecological disaster, and ultimately harm human beings and harmful animals. This definition is given by us humans.

It's harmful by our standards. It's bad for us, but maybe, it's good for other living things.

Harmful or not, these are actually people. But it's not man who has the final say in nature. Like a mosquito, it does spread diseases or something.

But it's also a link in the food chain. Without it, creatures like frogs will have no food, which in turn will increase the demand for other food, such as flies. But there are other animals that eat flies.

In the end, such a link will eventually endanger human beings themselves.

Pest animals cannot be completely eradicated, they are also part of the ecosystem, and if they become extinct, the ecological balance of the ecosystem will be lost, and there will be serious consequences. The second student was right.

Because of this ecological imbalance, it will cause a series of disasters, such as the woodpecker (or other bird) he eats insects, and the insects are pests, and if they destroy him, the woodpecker (or other birds) will starve to death.

That's probably why!

Take a look.

Harmful and harmless are relative, nothing can be generalized, what is harmful to human beings may be beneficial to other organisms, and beneficial to maintaining ecological balance.

Humans are the most harmful animals. But murder is against the law.

Unless it is a large-scale extinction, if there are one or two varieties, it should not bring great harm, and there should be no need to worry about this, but if there is extinction, there must be a bad environment.

Maintain ecological balance.

Since they are wild animals, that is, undomesticated animals, they will be hunted and killed by natural enemies and destroyed by natural disasters at any time in the wild, so we must especially protect wild animals and domesticated domestic animals. For example, there are only 200 white-sided dolphins left in the world, and if they are not protected, one less will be one less.

Every living thing has its value, and it is not a scourge to human beings that cannot be protected. But not to let them reproduce indefinitely, the original intention of human protection is to maintain an appropriate number, the domesticated pigs and sheep are because of the continuous breeding, people eat, will maintain the overall balance, if the pigs and sheep are less, they will also be as valuable as the white-sided dolphin, and the white-sided dolphin will be as readily available as pigs and sheep.

When we were young, we saw wild goats, turtles, and deer in the mountains, but now we can't see them, so we have to take care of wild animals.

Non-indiscriminate killing of wild animals is the protection of the ecological environment, which is conducive to the harmonious coexistence of man and nature, promotes sustainable economic and social development, and is also conducive to the health and development of human beings.

Regardless of shooting wild animals, it can protect nature, and it can maintain a balance in an ecological circle, which is also a benefit, and can protect some rare animals and plants.

I'm coming, you don't kill wild animals indiscriminately, what good will we have? I don't kill wild animals indiscriminately, wild animals are protected, so I can't kill indiscriminately.

The life of human beings has been developing towards the birth of high civilization and high technology, and the meaning of the existence of a species is to plunder nature and exterminate other species, but other animals have limited capabilities, so they can only be limited by nature, while human beings are different.

If you want to talk about harm to humanity.

If all the animals in the world are extinct, then humans will not be able to engage in biomimicry research, nor can they engage in biological and genetic research, and we will not be able to find animal experiments in clinical trials, but maybe we will not need these sciences at that time.

I don't think it's necessary, because animals and our planet are also in balance. It is a shameful act for some people to kill animals indiscriminately. If there are no them in the world, then there will be an imbalance in our entire biosphere, and sooner or later we humans will cease to exist, so please cherish the animals.

Without meat to eat, the food chain is broken, the ecological balance is destroyed, and humans can only maintain their health by eating artificial meat.

Why do we want to completely eradicate them, every animal has the right to live in this world, the earth is not human, humans are earth, we have to be kind to other species. For example, if there were no cats in the world: humans might indeed provide food for cats; But without cats, humans would have less food to begin with; When a cat on a small island was almost extinct, the local rat population quickly quadrupled.

Without other animals, we have no meat to eat.

Specifically, if there were no animals, meat would not exist, and human food would be reduced by a large part.

If there were no animals, then, in terms of the current biological balance, it would be upset. For example, without butterflies, plants that rely on animals to spread pollen would not be able to live, and from this point on, human food would be much less.

If there are no animals, such as fish and other small aquatic animals, then the planktonic algae in the water column will grow wildly, inhibiting the growth of other aquatic plants, so that human food will be reduced...

There are too many, and the more you talk about it, the more terrible it becomes, and the end result is that human beings don't exist anymore...

So please take care of animals.

According to this logic, animals should have exterminated humans long ago!!

In order to keep, the food chain is intact.

Carnivores, lions, tigers, exterminated and extinct.

Because animals are the friends of man!

I would say, what would humans be like without animals? If all the animals died, so would the human race. What befalls animals will eventually befall humans.

Humans have a close relationship with animals.

You've all read the text "The Old Man and Haiou"! How beautiful the seagulls are here. Look at how close the old man and the seagull were! How much the seagull trusts the old man, and we should learn from him.

People who eat meat will only get fatter and fatter the more they eat, and lose their ability to work. In the same way, the animals are also decreasing one by one, don't you feel distressed? Have you seen the original **?

How beautiful the sky, how beautiful the land, how many animals gallop in the endless savannah? Don't you envy? Animals, like humans, enjoy all the living conditions that Mother Earth brings to them.

They also have the right to live, so why do we humans have to deprive them of the law of survival? Can't you survive happily? Can't humans just eat vegetarian food?

Can't you coexist well with animals?

If we give up this land, Mother Earth will give up on us as well. Canaan tells you that there is no second planet that is habitable for humans at least within 40 trillion kilometers of the Earth. We can't expect to move to other planets after destroying Earth.

Someone will say, "We can go to the moon or go on fire to create a base for immigrants." Jianan told you: "If there is a migration base, how many people or hundreds or thousands of people will go up?" ”

Earth is selfless, and she generously provides humanity with everything that humanity needs.

Our planet is too lovely and at the same time too easily broken.

Please be kind to animals and be kind to everything on earth.

It seems that the more I read the book, the more confused I became, what is an animal, and whether people still want to eat meat;

In this world, there are too many things that should not be done, and people still hurt people;

This proposition is not good;

If humans who can't create humans are careful and use mature genetic technology to grow meat from plants, they will not be able to do it for food in the future.

Of course, it's not impossible to grow rhino horn or other works of art from plants.

If it is because things are scarce and expensive, then energy is created with intelligent programs, and the black technology of remotely transporting energy from black holes is almost mature. With (yin and yang) energy and intelligence, there is the capital of time and space control, and I don't know what else can't be made by making diamonds quickly**?

I don't know what humans can't do except to dominate themselves and understand the world that exists?
