My Daily Life with Gosara Ayase/my Sister Can't Be Ayase's Little Angel

Cats are not vegetarians, the bigger they are, the more powerful they are, and they are the top consumers in the ecosystem.

In most areas there are no natural enemies.

Taking Australia as an example, at least 20 species of native mammals became extinct due to predation by stray cats.

As many as 338 bird species have been hunted by stray cats, 71 of which are already endangered species.

To this end, Australia has also launched a large-scale hunting operation.

Recently, there has been a proposal to kill 200 million stray cats.

Until now, some places in Australia have been rewarded by the government for killing stray cats.

Australia has achieved good results by establishing cat-free areas to restore the ecology.

Taking the cats in the Yingjiang area as an example, they can kill 14-37 billion birds and 69-207 billion small mammals every year.

This is in the wild or in the outskirts. At any rate, you can find some animals that are not persecuted by cats, or animals that can compete with them, or kill cats.

In the city, in this steel forest, cats would have no natural enemies at all.

Birds are the biggest victims of what they catch.

That's why I said that domestic cats are already supported by people, so they don't need to go out to hunt, but they can also accompany people, which is useful and harmless.

But if it is a wild cat, it is completely an invasive species, harmful and causing great damage to the local ecosystem.

So I don't like, especially feral cats. "

Ryunosuke pursed his lower lips: "I know about invasive species, such as crayfish that are delicious and extinct and require artificial cultivation.

For example, there are so many scavengers that are useless and delicious.

But cats seem to have existed in our country for thousands of years, why are they still invasive species? "

Yang Nai shook his head and smiled: "This is still a habitual misunderstanding.

Although cats and dogs are both domesticated by humans, they have also existed in our country for thousands of years.

But dogs are domesticated from wolves, and stray dogs can be treated as wild wolves.

Whatever wolves do, they have matching food and natural enemies, and the ecosystem can be adjusted.

Cats, on the other hand, are completely human pets obtained through hybridization. They are not born normally in nature, so there is no matching food and natural enemies, and the ecosystem cannot regulate it.

After thousands of years, the ecological balance of life has not yet been formed, and it is still an invasive species all over the world.

In addition to the suffering Australia, there are many countries that are infested by cats.

Some countries with a tough attitude, such as Poland, can kill cats at will, regardless of whether they have owners or not.

So I don't like it, it's useless and harmful, will you like it? "

"This" Ryunosuke looked down at the dark clouds and snow in his arms, "

After what you said, I feel that I have gained more knowledge, and my attitude towards cats has also changed. "

"Oh? How did it change?" Yang Nai stared at her with a smile, as if to get an answer.

"The senses are poor," Ryunosuke said somewhat complicatedly,

"After all, it belongs to the cat family like tigers, so it can be regarded as a miniature version of tigers. Not only do they have no natural enemies, but they also reproduce very quickly.

If we wait for it to replace some kind of predator, or form a new ecological balance, we probably won’t see it until human beings are extinct.

If the ecosystem has been destroyed, the extinction of human beings is almost a certainty. "

"Haha, this is a demon that has existed for thousands of years and was created by humans."

Yang Nao is very happy that Ryunosuke agrees with her, and they both like dogs, not cats like Yukino.

Ryunosuke forced himself to laugh a few times, but his expression was still a little unnatural.

In a cat cafe, it's weird to say such things.

Alas, but the appearance is deceiving.

He thought for a while and said, "Since you think so, let's go somewhere else?

We are just investigating, not necessarily playing here. "

"Okay, but the coffee is almost ready, let's go after drinking it?" Yang Nai smiled while holding the white cat in his arms.

"Well, now that you say it like this, it's unnatural for me to stay here. Where are we going to play?"

"Would you like to ride a horse with me?"

"Huh? Riding a horse?" Ryunosuke's expression changed, but he shook his head after thinking about it.

"I am also very interested, and you have this hobby, but if I go, I will not know how to ride, and it will take a while to learn, which is not fun enough.

Why don't we go to a place where even beginners can play?

About the horse, you can teach me slowly in the future, and I will go later. "

"You don't mind, what about playing golf?" Yang Nai suggested again.

"I haven't played this before, but you can go and have a look."
