Australia has been tossed around by a billion rabbits, so why not make spicy rabbit head? It's a sad nation that can't eat.

For Sichuanese who love spicy rabbit head, it's hard to imagine a place in the southern hemisphere where rabbits abound.

Australia has suffered three ecological catastrophes, all of which were caused by the fragile ecology of the area.

The first ecological disaster in the 18th century, in 1770 the Australian colonialists introduced cattle, the development of animal husbandry, Australia has a large number of natural pastures, rich groundwater, warm climate, no snowstorms in winter weather, coupled with the absence of tigers, leopards, wolves and other ferocious beasts, it is very suitable for the development of cattle industry. However, after some time, people found that the feces dispatched by cows on the grassland amounted to 100 million kilograms every day. These massive amount of cow dung, covering the pasture grass, affecting the photosynthesis of plants, causing grassland pasture grass to die in pieces, at the same time, the dung also a large number of mosquitoes and flies, seriously affecting the environmental health. 20's Australian scientists from China introduced the dung beetle, the dung beetle introduced to Australia, a large amount of dung as their own nursery and food, the perfect solution to the cow dung crisis.

The second ecological catastrophe came in the 19th century, when a cactus, the prickly pear, entered Australia in 1840 as an ornamental plant, only to spread wild. Arable land and pastures were taken over by prickly pear at an alarming rate. By 1925, the prickly pear has occupied about 240,000 square kilometers of land, people began to use knife cutting, car rolling, fire and other methods to deal with prickly pear. The result is all to no avail. Finally, scientists found a kind of spotted borer family moth larvae, as the prickly pear's natural enemy. This kind of insect once encountered the prickly pear, will enter the plant inside to him completely empty eat all. Ten years later, the prickly pear crisis was largely solved.

The third ecological catastrophe is the hare crisis of the 20th century to the present. In contrast to the cow dung crisis and the prickly pear crisis, Australia's hare problem is even worse. At its peak, the total number of hares reached more than 10 billion, equivalent to hundreds of times the total population of Australia. A large number of rabbits breed in the grassland, eating the pasture that should be fed to cattle and sheep, and digging holes and building burrows everywhere, destroying the roots of the pasture, causing extensive degradation of the pasture and posing a serious threat to the development of the animal husbandry industry.

Australia is a no-gun country, and the government encourages people to kill rabbits and offers incentives to do so. But with rabbit populations dozens of times larger than those of humans, and their ability to reproduce even more perversely, Australia can't kill all of them, even with a full military force.

Humans can't beat rabbits, so we turn to foxes for help. The foxes were as cunning as the cats, but they were not as cunning as the cats, and they did not want to catch the mice! The foxes have not only failed to catch the rabbits, but have also made it impossible for the sheep to survive. So Australia had to catch foxes to protect the sheep.

Rabbits are life, and it's not good to push them too hard. The Australian government began to follow the example of the U.S. military in the Vietnam War, building barbed wire fences around the country to isolate areas and create "rabbit-free zones. As a result, the rabbits learned guerrilla warfare by themselves, digging a few holes to infiltrate the area. Australia has failed in another roundup of rabbits.

At the end of the 20th century, the advent of genetically modified organisms (GMO) technology brought a boon to Australia's rabbit crisis. Scientists began using GM technology to work out a mucus tumor virus that was released into hares. If a female hare is infected with this virus, she produces antibodies against her own eggs that can damage them and prevent fertilization. This reduces the hare's ability to reproduce and makes it much easier to treat.

So, my Sichuanese friends are asking, if we launch a "spicy rabbit head" campaign, can we exterminate Australia's one billion hares?

All I can say is that it's a bit difficult.

How many rabbit heads does China eat each year? That figure was 500 million three years ago, is it possible to reach 1 billion now?

Even if so many rabbit heads are eaten in a year, a rabbit head is only a few dollars, and with the rest of the rabbit, the purchase price of a rabbit can be as high as 20. Can such a purchase price support a large number of rabbit hunting teams?

The answer is not enough. At best, a flood of hares in Australia would bring down the cost of local spicy rabbit heads.

An obvious example is that one year our village was infested with bean green worms, and many villagers heard that a catty of bean green worms could be sold for 10 dollars, so they went to their own fields to catch them, and the bean green worms, as big as their index fingers, were all over the place. The result of a day down the back pain, found themselves only earned twenty or thirty dollars, to do what is much better than this, right? The next day, I'm afraid that only the more courageous children to go to catch the bean green worm.

Don't laugh at Australia, but China's bio-invasive situation is not good at all. China has more than 620 invasive species, causing more than 200 billion yuan in damage, and 51 of the world's 100 most threatened alien species published by the International Union for Conservation of Nature, making it one of the worst countries in the world for biological invasions. Species you thought were delicious like lobsters (marbled shrimp) and locusts are actually quite ubiquitous in many parts of the country. By the way, a number of people on Jitterbug have called for cooking and eating scavenger fish to mitigate biological invasions, and there's a lack of people actually opening their mouths to eat them.

Biological invasion is a world subject, the emergence of genetic modification technology is considered to give people the best weapons. From here it is easy to see that the so-called science and technology is the first productive force, not only applies to the production of goods, but also in the protection of the environment.

The so-called rely on food to save species invasion, in fact, is a kind of ridiculous thinking, which shows that our science and technology is still not developed enough.
