Humans stand at the top of the earth's food chain, it is reasonable to say that there is no heaven and earth, even those lions, tigers and other beasts, are not the opponent of humans. Although humans hardly exist in heaven and earth, but it does not mean that we are "Invincible", sometimes in the face of some creatures are also very helpless. For example, in australia there is such a situation, the "Man-rabbit war" Lasted for more than 150 years, australia lost, the locals can not even handle the cute little rabbit? What's going on?
From 24 to 10 billion
I believe that many friends have raised bunnies, bunnies this kind of small animal is very docile, very cute, did not expect that the reproductive capacity of these bunnies is actually quite amazing, in australia the most rabbits even reached 10 billion, the locals simply can not completely eliminate them.
According to darwin's origin of species, in 1859, 24 baby rabbits were brought to australia from england, and after they were placed in the wild, they soon became "Overpopulated" Because there was almost no room for them in australia. It took only a few decades for the 24 bunnies to reproduce 10 billion offspring, and the emergence of so many bunnies brought devastating disaster to the local ecosystem. This is because 10 billion bunnies eat the pasture of 1 billion sheep every year.
Although the bunnies do not attack other animals, they need a lot of grazing to survive because of their extremely large numbers. This has led to a situation where they compete with other native animals for grazing on the prairie, eventually leaving some very docile native grazing animals facing extinction, or even extinction. Because forage is limited, native grazing animals grab food simply can not grab these small rabbits, rabbits are too much.
The main reason why the bunnies were able to flood from 24 to tens of billions is that the reproductive ability of the bunnies is quite amazing. Rabbits have 2 wombs, both of which are capable of conceiving separately and can give birth to baby rabbits, and can give birth to a litter of bunnies in a couple of months, each time they can give birth to several, so that a bunny "Couple" Can give birth to dozens of bunnies a year. In addition, there is almost no world in australia, so the survival rate of bunnies is relatively high. As the offspring grow up, they will also begin to reproduce rapidly, and in this case the bunnies will be flooded.
These bunnies have caused an imbalance in the local ecosystem and brought a lot of trouble to the local people's lives. Why don't the locals eat the bunnies? Or catch them and export them to foreign countries? In fact, the australian people actually eat bunnies, and the locals have come up with many ways to solve these bunnies, one of which is to call on the local people to hunt and use the bunnies that are flooding the country. But the number of these rabbits is too much, plus their reproductive capacity is too strong, the speed of the local people eating rabbits can not catch up with the speed of reproduction of rabbits, only to a certain extent to slow down the speed of reproduction of rabbits.
Since the locals can't solve these bunnies by eating them themselves, they will introduce foxes as natural predators. In theory, the fox is the natural enemy of the bunny, after the introduction of the fox should be able to effectively control the local bunny, but the actual situation is not as smooth as imagined. However, the actual situation was not as smooth as expected, because there are many cute little animals in australia, and these native animals do not know how to run for their lives after seeing the foxes, but stand there dumbfounded, so for the foxes to kill other cute little native animals is simply effortless, why do they still go to the effort to kill the little rabbits? The end result was that not only did the introduction of the foxes not control the number of bunnies, but eventually even the foxes flooded the area. The "Man-rabbit war" Lasted 150 years and australia lost!
