Why are many animals considered delicacies around us, but are overpopulated abroad?

We can always see all kinds of exotic delicacies on our dining tables, and most of these delicacies are animals that are prevalent abroad. For example, the fish we eat most often is abundant abroad. , it is true that it is a delicacy around us. Why is it that the same animal has completely opposite results at home and abroad?

It’s because foreigners don’t know how to eat. Their food culture is not as rich as ours, and their understanding of food is not as profound as ours. In many cases, when foreigners deal with overpopulation of animals, they have to spend a lot of money to eliminate them, and they have no better way, so it is impossible to keep these animals from overpopulating.

For example, we all know that wild boars and hares are overpopulating abroad because foreigners accidentally brought them over. In fact, we have also made such "mistakes", such as water hyacinth. , crayfish, snapping turtles, white snails, Brazilian turtles, etc. Of course, some alien species have become "jokes" around us. For example, the crayfish that invaded our place were eaten by us, giving rise to industry and culture, and became delicacies in our mouths. .

Why is this? For example, crayfish, carp, predatory birds, mussels, pythons, wild boars, kudzu, honey bees, hairy crabs, bullfrogs, Australian wild boars, carp, rabbits, foxes, etc. were all prevalent in the United States. In the past, these animals did not exist locally. But now the invasion of these animals has become animals that the local natural environment cannot digest at all.

First of all, we need to know that these alien organisms that can invade other places are caused by humans. A large part of the animals were brought there as food resources earlier, like the rabbits and wild boars we just mentioned earlier. Food for foreigners, but as foreigners developed, they looked down on these foods less and less. This can be said to be completely opposite to us.

For example, the mussels that have proliferated all over the world were adsorbed on the bottom of ships and spread all over the world through human voyages around the world; while the overpopulation of kudzu in the United States was brought there because Americans like to admire the flowers of kudzu. ; The tumbleweeds that are flooding North America are said to have been deliberately planted by the Soviets.

Here is another funny thing to tell you. We all know that carp and crayfish are rampant in Australia. There is a saying that early Australians had never seen carp and admired carp jumping and eating in groups. They were introduced as ornamental fish, but later the carp became too fat and lacked vitality because they had no natural predators. The Australians introduced crayfish and carp into an aquarium, and used crayfish to stimulate the vitality of the carp. As a result, the two animals It's all over Australia.

We also know about the proliferation of hares and foxes in Australia. Originally, foxes were not native predators in Australia. They were introduced to prey on hares, an exotic and widespread species. As a result, they found that foxes prefer to prey on marsupials. , it can be said that foreigners have done many wrong things in the process of global species proliferation.

Here we need to figure out "why some animals that are rampant abroad were originally food for foreigners, but later were not food for foreigners?" This will also help find the reasons for the proliferation of animals abroad. .

For example, wild boar includes pork. When we went to the United States earlier, it was packed with black people on the bottom of ships for black people to eat. We will not introduce the status of black people at that time, so pork is said to be food for black people in the United States. , So far, pork is not the main food of Americans, and some black people do not eat pork now.

Furthermore, after the industrial revolution and renaissance in the West, the resources at the disposal of foreigners have become more abundant, with more per capita possessions. When they are full and full, they start to read the books that believe in them. According to the teachings, don’t eat anything of unknown origin, don’t eat anything that doesn’t conform to your own culture, etc.

Secondly, because of environmental pollution, foreigners have also abandoned some food ingredients such as Asian carp. Americans also ate river fish earlier, but because industrial development in the early last century polluted many rivers, they believed that eating these Animal meat can cause physical discomfort.

In terms of eating habits, foreigners do not like to touch food with their hands, and the knives and forks they use cannot easily eat some foods, including hairy crabs, river fish, and bullfrogs.

When we look at these animals around us, there are not only various rich practices but also culture, such as fish every year and some poems about eating hairy crabs, etc., all of which tell us that these things are tasty.

So the animals that invade and proliferate abroad are first caused by human activities. Some of them were originally foreign foods, but later they were caused by differences in technological progress, environmental pollution, cultural beliefs, and eating habits due to the lack of awareness of biological invasion at the time.
