Why can Australia in the animal kingdom tolerate so many animals running wild?

As we all know, there are many kinds of animals in Australia, which can be said to be bullying the weak and fearing the hard on land. The local residents are even very scared, but we can't eat some animals that are allowed around us like our country, just to protect the ecological environment.

There are so many kinds of animals on Australian soil because of the evolution of geology and species. Oceania is separated from other lands and exists in the ocean alone. On this separated continent, there are no giant wild animals such as lions and tigers as natural enemies of small animals, but the largest is the Australian hunting dog, so the evolution of species is very slow, and many ancient animal species that have existed for tens of thousands of years have been preserved. Therefore, even without natural enemies, the Australian people need to protect them.

Because there are not many species in Australia, if the Australian people don't protect every species on the island, the extinction of one species may lead to the extinction of many species because of the food chain, thus destroying the local environment and ecology, and then affecting human habitation. Another reason is that the Australian people really like these small animals living around them, and animals will not cause them personal harm. Peace is the best way to live.

I also have to say that the Australian people have a really good temper. Every year, a large number of animals migrate, but some animals die in road accidents. Lovely, they built a bridge specially for migrating animals to protect them from being hurt when crossing the road. I hope that people living in the inland will also learn to protect the animals around us from harm.
