"Go to the fields to catch insects", with a bit of a local flavor is now gradually unspeakable in the countryside, when we gather our eyes on the countryside, we will find that the insects that used to be a lot of insects are now almost gone.
Take Malu as an example to illustrate that as a common insect in the countryside, everyone can inevitably meet it as long as they go to the field, but the current situation in the countryside is that if you want to see Malu, you have to go to find it, otherwise you can't see it.
Although it is a good thing for farmers to say that the number of horses is decreasing as a species that harms crops, this unusual situation has also made many people wonder why the number of horses is decreasing.
First of all, let's reverse everyone's perception of Malu, as an agricultural pest, Malu has a unique application in the field of medicine, which can have a maintenance effect on the stomach, and this turn also shows that the value of living things is often latent.
Looking back on the evolution of Malu, if the giant Malu with a length of 3 meters in the Carboniferous Period is resurrected now, there is no doubt that it will develop into a human disaster, and it can go through the erosion of time to the present, Malu naturally has its own set of survival rules.
Unlike centipedes, Ma Lu is not very aggressive, and will first choose to curl up to avoid enemies, and if the enemy still does not choose to retreat, Ma Lu will release a stench, which is not only an irritating gas, but also contains a certain amount of toxin.
For the body's immunity, this part of the toxicity is only enough to cause redness and swelling, but if it is other insects, it is estimated that it is difficult to survive intact, which also shows that although Ma Lu has given up the huge size of several meters in the long evolution, he has other means of protection.
In the final analysis, it is the result of natural selection, if Malu does not make a change under the condition that the high oxygen environment disappears, it will also go to the same end as other extinct large insects, and now it seems that Malu has become weak, but in the end it has survived.
For individuals, strength and weakness are naturally of great significance, but from the perspective of the ethnic group, the significance of individual bravery is small, and it is the most important thing to survive, so this toxin has become the umbrella of Ma Lu.
Although the toxin of Malu is not fatal to the human body, if the smell on its body is contaminated with you, it will not dissipate in a few days, and even if you don't pay attention to it, you don't want to let yourself have an unpleasant smell, let alone a few days.
So subconsciously will avoid Ma Lu, in this way, Ma Lu's talent makes it much more resistant to risks in the insect world, so why is the number of Ma Lu still decreasing under such an effective self-protection mechanism?
In fact, the answer is very simple, the change in the number of organisms can be divided into several reasons, the first is environmental problems, in contrast, farmers are now using less and less farm fertilizers, most of them are chemical fertilizers.
As a result, the environment that Malu itself likes to live in has begun to be full of chemical fertilizers, which has brought great challenges to their survival, and finally the overall number of them has continued to decline, in addition to this, Malu is also facing another danger.
As mentioned above, the insect itself has medicinal value, and the purchase price is still relatively high, which makes many people begin to capture the horse to obtain benefits, although the growth of the speed of the horse is not slow, but it can involve making money, and there are more people who catch insects.
In the supply circle of the road, there are many people who choose artificial breeding, and in the case of hundreds of spawns in Malen itself, artificial breeding is still needed to meet the market demand, which can be imagined that the demand for the road in the traditional Chinese medicine industry is conceivable.
Then there is the problem of Malu itself, if Malu is a beneficial insect, there may be some room for maneuver, but they are pests to crops, and the attitude of farmers towards the road is naturally not better, and the end result is chemical fertilizers and insecticides.
Under the two-pronged situation, the living environment of Ma Lu is even more worrisome, many Ma Lu have just come to the field, and they are killed by the pesticides sprayed on it, and finally it is naturally more and more difficult to appear in front of the people.
Finally, the development strategy of the countryside has allowed many villages and towns to enjoy the dividends of development, and began to engage in construction, when it comes to construction, quicklime is indispensable, but the most hated place in Malu is the area where quicklime is everywhere.
The expanding quicklime content of rural construction has made Malu, who seeks benefits and avoid disadvantages, also choose to stay away from the townships, so the problem is, one is urbanization, the other is rural construction, and there are chemical fertilizers in the fields.
After these three directions were blocked by humans, the living environment of Ma Lu has gradually disappeared, so even if you come to the countryside, you can rarely see insects like Ma Lu, and you can only occasionally see them in some fields, which is also more impressive.
