Bright white, prominent bulbous forehead and their irresistible classic smile are the striking and prominent signs of Moby Dick. 2065438+In September 2008, a white whale appeared on the Thames in England, which quickly attracted people's attention. It quickly won a friendly nickname-"Moby Dick Benny". Beautiful photos of its beautiful figure soon spread all over the world. However, why did "Benny" appear on the Thames far from home-a place far away from its usual range of more than 3,000 kilometers? Benny's arrival may be a timely warning to remind people that the Arctic is undergoing tremendous changes, and the Arctic "ghost" beluga whale, as a huge marine life species, may be facing severe difficulties. This has sounded the alarm of the earth's ecology for us. Being "imprisoned" by human beings, this ghostly white arctic whale is really cute, but sadly, because of its cuteness, many captured white whales are put into aquariums for tourists to pay for viewing. In Vancouver Aquarium, a female beluga whale named Aurora swims around her trapped aquarium. The aquarium looks very big, and the walls in the distance are made of stone, which simulates the natural environment where the beluga whales once lived, but it still can't change the fact that they are imprisoned. This aquarium with Aurora in captivity can only be regarded as a "square inch" for Aurora who once lived in the vast ocean. In the same way, it will go back and forth regularly in the "circle", float or sink, be swam sideways by tourists, and then continue to repeat its parade in this small circle with its eternal "smile". Its charming "smile" makes children and adults can't help but smile back from the heart. It's so lovely to aquarium visitors that it attracts many visitors like a magnet. The "smile" of beluga whales is due to their ability to change their mouths when they make sounds, which seems to be "smiling", and this ability is rare in whales. However, once you see the wild beluga whales living in the vast ocean free world, or photograph their graceful figure jumping on the sea surface, it is hard for you to accept the human behavior of keeping them in captivity. No matter how carefully the staff and animal trainers take care of these captive beluga whales, they can't change a harsh fact: it's like a person being placed under house arrest in a windowless room, isolated from the colorful natural environment of nature, and losing his due complete life experience. After the death of Aurora, who was trapped in the aquarium for a lifetime on 20 16, the voice against captive beluga whales became louder and louder. Under pressure, Vancouver Aquarium recently announced that it would stop keeping whales and dolphins in the aquarium. Unfortunately, this did not change Moby Dick's tragic fate. In other parts of the world, beluga whales are still suffering from human disasters. A Moby Dick specimen is worth more than $250,000. Whaling and selling whales are big business in Russia. It is reported that there are at least 1 1 wild killer whales and 90 wild beluga whales in the aquarium of a city in the Far East of Russia. Normally, Russia issues quotas every year, allowing more than 150 white whales to be captured from the wild for educational, cultural or research purposes. But the fact is, not all these whales captured and kept in captivity can be used for these purposes. The beluga whale with broken family is a species with perception and emotion, and is used to long-distance migration in the ocean. However, in the process of catching, whalers will only take away their young whales, leaving them bereft of their parents and children and mercilessly destroying their strong family and social relations. Captured beluga whales must be squeezed for months in small captivity. Such a harsh living environment has greatly shortened the life span of these beluga whales. It is estimated that there are about 3,000 whales and dolphins in 300 aquariums in 50 countries, and another 36 similar large aquariums are expected to be completed and opened in the next two years. In response, the Whale and Dolphin Conservation Organization cooperated with the Marine Life Trust to open the world's first whale sanctuary to rescue them and release the captured whales into the marine natural environment. However, another grim fact is that even if they are put back into the ocean, the wild environment of the ocean has become increasingly unsuitable for the survival of beluga whales. In parts of Alaska, Canada, Russia and Greenland, indigenous communities continue to kill beluga whales for meat. Their practices are completely legal and there is no relevant law prohibiting them from doing so. Once trapped in the ice, beluga whales are easy targets for polar bears. But perhaps most importantly, the final blow to the fate of these beluga whales is the warming Arctic climate, and global climate change is destroying the Arctic habitat on which beluga whales depend. People have always wondered why the great white whale appeared on the Thames, far away from the Arctic home. Some people think that it may be lost by the busy shipping traffic of human beings, and the noise generated by ship navigation will interfere with their echo positioning system. But it is more likely that the rising temperature in the Arctic Ocean will lead to an increasing shortage of food for whales, forcing whales like Benny Moby Dick to go further afield in search of food. The impact of climate change on beluga whales can be seen from the experience of a group of trapped beluga whales. These beluga whales were first discovered by people who came back from hunting seals. It turned out that a few days ago, an unusually strong spring storm blew away hundreds of square kilometers of originally solid sea ice, forming a huge open water area called an "ice cave". For the next few days, the sea remained calm. A group of about 70 beluga whales cruised north in search of food. They swam farther than usual, and finally entered this ice cave and dived in this open water for food. But what I didn't expect was that a cold current of MINUS 35℃ suddenly came one night, freezing this sea area, and this group of beluga whales were trapped here. Source: natural exploration
