Only by obeying nature can we defeat nature. —— Darwin
Have you ever thought that you paired with cold beer in summer and ordered plate after plate of crayfish, which is a species illegally invasive from abroad. And the crayfish that appear on our table are basically artificially farmed, so no matter how much you eat, it has no effect on those crayfish that are still invading in the wild.
Species invasions like crayfish are being staged in various countries all over the world. If you think about it, food-eaters like us cannot avoid it. It is really difficult for other countries not to suffer species invasions. In Australia, there is an invasive species that is very popular among Chinese foodies, and that is the rabbit. Rabbits in Australia can even grow to close to one hundred catties.
It's not that Australia doesn't eat rabbits, it can't be finished.
Sichuan foodies don't question, why are rabbits so delicious and Australia doesn't put rabbits on the table? Does Sichuan Foodie still want to eat rabbits as endangered animals? There is nothing wrong with the idea of Sichuan food. The number of rabbits that die in the hands of Sichuan chefs can be up to 300 million each year. It can be said that it is the place where the most rabbits are eaten. This number seems to be a lot, but according to the statistics of relevant Australian departments, Australia There are 10 billion rabbits when the number of hares is the most!
Does the Australian people know how to eat rabbits? That is not enough. Even if these rabbits are given to the Sichuanese who are most able to eat rabbits, they will have to eat more than 30 years to solve the 10 billion rabbits.
Besides, rabbits in Australia can grow up to 100 catties, not much smaller than piglets. Compared with rabbits in Sichuan, they are much larger. Sichuan people may not eat 300 million rabbits a year. In the past 30 years, rabbits Rabbit sons will have rabbit sons, and rabbit grandchildren will be born to rabbit sons. In this land of Australia, rabbits have endless descendants.
The reason for the proliferation of Australian hares
Rabbits can be powerful in Australia,Part of the reason is that the reproductive ability of the rabbit itself is too strong, and the six-month-old rabbit can mate and give birth to baby rabbits, and it is more fertile. In other words, a new batch of rabbits will appear every few months.
In addition, Australia’s natural environment has no natural enemies of rabbits and there are vast grasslands to provide sufficient food for rabbits. Rabbits in Australia eat and drink and give birth to little rabbits. There is nothing that can threaten rabbits. life.
The other part is the environmental reasons of Australia. Australia is essentially an island. The natural environment remains independent for a long time. Compared with other ecosystems, Australia's ecosystem is very fragile. The first rabbit to appear in nature in Australia escaped from a house on fire by a British officer.
The British military officers brought a total of 24 rabbits. Even one was not burned to death. The number of rabbits from 24 to 10 billion is enough to show the reproductive capacity of the rabbits and the fragility of the Australian ecosystem.
The Australian government tried every means to control the hare
The rapid increase in the number of rabbits in Australia soon caused great damage to the local ecological environment in Australia.
Australia has also thought of a lot of ways to deal with the problem of rabbits flooding. In the beginning, they used the method of introducing natural enemies. Australia has no natural enemies of rabbits, so foxes are specially introduced.
This method is theoretically feasible, but after it really landed, it did not start in the direction of the imagination of the Australian people. Not only did it fail to make the rabbit disappear, but it also made the fox the most threatening in Australia in this land with sufficient food. One of the invasive species, the number of rabbits continues to increase, and the number of foxes continues to increase. The rabbits will continue to increase if they can't eat the foxes, forming a direct ratio. The final result of this method can be said to be more than worth the loss.
The people of Australia are mainly concentrated in the coastal areas, and there are few in the central part, and the places where rabbits are flooded are those prairies in the central part. Humans cannot be gathered together to deal with the overwhelming rabbits, and their numbers are not enough in front of the rabbits after the outbreak. For people living in the central region, rabbits can be eaten after they are caught, and foxes are useless.And even if humans were deployed to catch foxes, the speed of catching them would not be as fast as the speed reading of breeding, so the first method declared a complete failure.
Later, the anxious Australian people thought of an extreme method, that is, to develop a virus that specifically targets rabbits that are useless to other animals. This method was very useful at first, and the progress of the victory reached 90%. But after the virus took a long time, antibodies appeared in the rabbit's body. The virus suddenly lost its effect and the rabbits began to flood again.
In order to continue to eradicate the virus, the government has developed new viruses, forming a mutually restrictive balance with rabbits. Up to now, the problem of the infestation of rabbits has not been really solved.
Conclusion
Species invaded and flooded, which is a big problem all over the world. Although our country does not expect Australia to have such a large area of invasive species, but there are also many alien species. The destruction of our ecological environment. In general, observing the laws of nature and living in harmony with nature are the most important.
