When watching military programs, every time there is a maritime exercise, the troops have to launch many artillery missiles into the sea, and so many ammunition explodes in the sea, and the marine life nearby will definitely be doomed. So, where did all these killed fish go? Will it be scooped up by the army? Is it okay to sell it in the market?
How many fish can be killed in a military exercise? According to the statistics of the Marine Animal Protection Organization of the United States, a medium and large military exercise will cause 15,000 marine mammals to be harmed, 1 million marine fish and various molluscs will be affected, and more than 5,000 medium-sized fish will be directly killed.
Many people think that this data is exaggerated, but in fact, the harm caused by military exercises to the ocean is huge. Military fans who know a little military common sense may know that the distance of grenade fragmentation in the water is very close, because the resistance of water is much greater than the air, so some people on the Internet said that he bought a sea fish after steaming, found a shrapnel in it, speculating that the fish was killed by a shell of a naval military exercise, in fact, this situation is rare.
Because most of the shells used by the Navy are not fragmented, the Navy's weapons are mainly for the destruction of enemy ships, and rarely against the crew, so the Navy's missiles and shells are loaded with high-explosive charges, and shrapnel has little effect on marine fish.
But the shock wave generated by a high-explosive explosion is still fatal to marine fish because sound travels very quickly in the seawater. The same is true of the shock wave, not only fast, the energy retention effect is also very good, a two-ton torpedo can cut off a 10,000-ton cruiser, in fact, because the shock wave of the explosion in the sea water will be amplified, if it is on land, there will not be such a good effect at all.
As a result, many fish were not injured by shrapnel, but by the shock wave and gutted, even if they did not die immediately, but within a few days after the exercise.
In addition to the effects of the shock wave, the sewage produced after the shell explosion is also highly toxic, and if the fish come into contact with these substances, they will definitely be poisoned. Take TNT, for example, many people know that its composition is trinitrotoluene, which is powerful in explosion. But few people understand that it is also a highly toxic substance in itself, and the high-explosives used by the Navy are even more toxic.
This is another shock wave and poison, and a large number of fish will naturally die when they touch it, so the data given by the marine animal protection organization of the United States is not an exaggeration.
So the question is, how did these killed fish end up? Will the Navy scoop it up and eat it?
In order to show its strength and at the same time consolidate its sea power, the US Navy conducts dozens of large and small military exercises every year, either on the military exercise or on the road to military exercise. So if you want to say which country in the world blows up the most fish, it must be the US Navy.
U.S. Navy GIs don't look at these dead fish and usually ignore them. In fact, there is no better way to deal with these killed fish, because the Navy is not like the Army during military exercises, their range of activities is very large, the range of an anti-ship missile is more than 300 kilometers, 300 kilometers away the killed fish, how can the Navy recycle?
In addition, if these fish absorb the toxic substances of high explosives, then it is harmful to the human body to eat, so the US Navy will not salvage and recover these killed fish. Even if you want to recycle it, there are no conditions, I have never seen any navy with a fishing net dragged behind it during an exercise, and there is no space inside the warship to store these fish.
Moreover, these fish need to be frozen after being recycled, and there is no large freezer on the warship, how to preserve these fish? Over time, it will stink and rot, and if the Navy wants to eat fish, it is better to stand on the deck and throw a few rods down, if the regulations allow.
If fishing boats are launched to catch fish, the fish cannot be sold to the market because they have toxins in their bodies. In addition, although the missile has eyes, it can not tell which of the ocean's fish can be fried and which cannot be fried, in case it is blown up to protect the fish species, the civilian salvage ship catches it and puts it on the market to sell, and the boat owner is likely to eat prison.
So are these fried fish wasted like this? The fishermen's hearts were probably broken after seeing it.
The ecosystem in the ocean is not as fragile as human imagination, you know, so far human exploration of the ocean is only 5%, the remaining 95% is unknown, the ocean not only has breadth, it also has depth. Although each exercise has caused a large number of fish deaths, these are only a drop in the ocean for the ocean. Japan's discharge of nuclear sewage is much more damaging to the oceans than naval exercises.
Under pressure from environmental protection groups, the U.S. military will be equipped with a high-powered sonar boat during naval exercises, which will be used to drive away fish in the exercise area. In fact, this method is done for animal protection organizations, and people who know a little about physics know that the US military is perfunctory, sonar not only can not drive away fish, but also cause harm to marine life.
Especially for mammals such as whales and dolphins, because they also use sonar to judge the direction, in recent decades, there have been news that whales rushed to the beach to commit suicide, and the reason behind it is likely to be that the sound waves caused by human sonar make whales lose their ability to judge, become deaf and blind, and finally rush to the beach and run aground.
The most environmentally friendly way to conduct naval exercises is to design uninhabited islands so that they do not harm the animals in the ocean. No uninhabited islands can also be replaced by large scrapped ships, do you think this method is good? Feel free to comment below.
