Since 1967, every once in a while, Australia has spent a lot of money to import a batch of shell langs from China, mainly to clean up the cow dung in their pastures. If there is no shell lang, then their country's cow dung will soon pile up.
To solve this problem, Australia has to spend a huge amount of money to import shell lang from many countries. At this time, some people may wonder, is there no shell lang in Australia? Why import from other countries?
In fact, it is not that their country does not have shell lang, but their country's shell lang has long been raised to be very picky eater, so they need foreign aid to help. Just like china's men's football team, if there is help from foreign aid, perhaps the performance will be improved.
Introduction to Shell Lang
The original name of the shell lang is dung beetle, and the shell lang is just their common name. There are more than 20,000 species of dung beetles in the world, distributed on any continent outside of Antarctica. The most famous dung beetle lives in Egypt and is 1-2.5 cm long. The largest dung beetle in the world is the 10 cm long giant dung beetle.
Adults are all black, about 3.5 cm in length, they feed on animal droppings, and have the reputation of "nature scavengers". They have a lot of strength and can push things that are 250 times larger than their own bodies, so they usually roll fecal balls that are so big.
It is worth mentioning that the shell lang eats the animal's feces, lives in the animal's feces, and even lays eggs on the animal's feces. It can be seen from this that the shell lang's love for feces has reached an extent.
Why should Australia import shell lang
First, clean up cow manure
According to statistics, there are currently about 28 million beef cattle raised in Australia, with an average of 1.5 cattle per person, ranking among the top in the world, with an export rate of 60%. Since there are too many cattle, the cow's manure is also piled up in mountains.
These cattle are not of origin, so the manure they pull down is moist and slimy. According to statistics, Australian pastures produce 80 million tons of feces per year, and it will take a long time if the feces are allowed to decompose naturally.
Due to the large number and increasing number of positions occupied, it has brought great obstacles to the development of animal husbandry. Although they can rely on manual processing, there is no way to clean it up, so they have to think of another way to do so.
Coupled with the fact that the local shell lang is picky and does not like this feces at all, so it can only import the shell lang of other countries, because the shell lang of other countries is not so pretentious, and almost no one refuses, so it greatly reduces the pressure on the Australian ranch.
Second, the local shell lang is too picky eaters
According to the data, there are actually 475 species of shell lang in Australia, but their traditional taste of indigenous shell lang is kangaroo and koala dung, until the British colonists brought cattle and cows to Australia in the 18th century.
However, the indigenous shell lang does not like the new feces, because the moisture in these cow dung is too large to compare with the kangaroo manure, these cow dung is not only wet but also sticky, the shell lang is very difficult to clean up, so it is not popular with the shell lang at all.
Unwelcome cow dung piled up more and more in the pasture, and more and more flies in the cow dung, street cafes were forced to put away outdoor tables and chairs, and everyone had to stay in the houses with closed doors and windows to avoid the flies.
In order to solve the problem, Australia is looking for foreign aid everywhere, and introduces 43 kinds of foreign shells from South Africa, France, China and other countries. The shell lang from the north is different, because they have been accustomed to the taste of cow dung since they were young, and soon solved the problem left by the old Australian cattle.
Third, only by relying on foreign aid can we solve the problem
Due to the accumulation of cattle and sheep manure in Australian pastures, it not only hinders the development of animal husbandry, but also causes more and more serious damage to the ecological environment. In order to solve this problem, in 1963, they launched a project called the "Introduction of Shell Lang Project".
The main purpose of this is to use foreign aid to solve the problem of cattle and sheep manure in their own countries, after comparison, they have introduced more than 50 kinds of shell langs from South Africa, China, France and other countries, with these "foreign aid", the manure problem of cattle and sheep has finally been effectively solved.
Maybe for the insects, these dung are smelly, but for the shell lang, these dung can all be delicious. Coming to the pastures of Australia, they are like coming to heaven, so they are overjoyed. In the case of eating, drinking and having fun, cleaning up the feces is only a matter of minutes.
shell lang way of working
Any species has a division of labor and cooperation, so as to improve the efficiency of work, and the same is naturally true of the shell lang. The way they work is mainly divided into three types, namely tunnel type, stool push type and fecal dwelling type. All three types of shell langs are particularly important and indispensable.
The push type only needs to dig a tunnel, then roll the feces into a ball, and then push the feces back into the hole. The tunnel type of work is to dig a hole under the feces to improve the efficiency of handling. As for the fecal type, their work is relatively simple, and they only need to lay eggs on the feces. Under the division of labor and cooperation, the population of shell lang can grow day by day.
What is the role of shell lang
1. Improve soil quality and improve plant survival rate
Although Australian cattle and sheep have a lot of manure, the soil in their country is not very good because of the influence of the environment. Mainly because the Australian climate is dry, it is difficult to break down this feces, so it is difficult for plants to absorb.
In order to make the soil fertile, it definitely needs good fertilizer to moisturize it. Although limited by the climate, the ability of the shell lang is not vegetarian, they are carried and digested, the various elements in the feces into inorganic salts, so that it is convenient for plants to absorb.
In this way, the growth of plants naturally accelerates, and the shell lang needs to make holes when storing food, which can help loosen the soil, and they hide the feces in the ground, which invisibly provides great help to the local animal husbandry.
Without the help of the shell lang, relying solely on manual treatment, presumably Australia's animal husbandry industry will inevitably be greatly restricted. But they are also really smart, knowing that the indigenous shell lang is not very useful, but to cause other countries.
2. Protect the ecological environment and control the number of flies
Because the feces of cattle and sheep contain a large number of sugars and proteins, they will attract a large number of flies. Watching them hover over the excrement of cattle and sheep, as long as someone passes by, they will fly, it is a headache.
It is said that the hatching speed of flies is very fast, and more than 3,000 small flies can hatch in cow dung in just seven days. But with the addition of the shell lang, it can greatly control the number of these flies and prevent them from hatching.
The shell will bury the feces in the ground before the flies' eggs hatch, so that they can directly kill the flies' eggs and prevent them from hatching. For flies, the shell lang is their natural enemy, so in order to hatch the eggs, it is necessary to avoid the shell lang.
Judging by the various abilities of Shell Lang, he is really a veritable "environmental expert". Not only can it clean up the feces, but also control the number of flies, but also can loosen the soil and protect the ecological environment, which shows how important the shell lang is.
Write at the end
Australia every year because of the problem of cattle and sheep manure needs to spend a lot of money, but these money they have to spend, even if other countries increase the price of shell lang, they can only silently accept, if not imported shell lang, local picky eaters, wait until the day the street is full of cow manure, it is not good.
