Britain is being attacked again by giant rats! The news was published by the British "Independent" quickly caused a lot of attention on the Internet, to know that in the past, the United Kingdom has accused India, Vietnam and other countries on the grounds of cleanliness and hygiene, and this time the face was cracked.
The size of the rat is estimated to reach the size limit of this species, and the rat with a body length of 30 cm can only be considered medium, because Norwich, the second largest city in England, once captured a giant rat with a body length of 53 cm, and it is said that cats and dogs will run on their legs after seeing it, hiding in the corner of the wall and shivering!
According to statistics, there are at least 100 million rats in the whole of the UK, what is this concept? The entire population of the UK is only 66 million, and at the rate of rat breeding, the number in the coming months is easily several times that of the population! Because there are too many rats, some rats are forced to leave the cave and migrate to people's homes and courtyards to "settle down".
Hungry rats sneaked down the sewers and eaves into the residents' kitchens and bumped into pots and pans: if there was food, the rats would flock to them; if there was no food, the angry rats would sometimes overturn the basins to the ground. Residents knew that rats had broken into the kitchen, but some of them ignored it, because the rats would soon come back after being driven away, and they could only wait until the next day to deal with it!
Some rats also sneak into the kitchens of schools and hospitals, including supermarkets with abundant food: the chef's dishes for the next day's students are eaten mostly by rats at night, and the rest is smeared on the walls and on the floor; there is a pile of rat droppings in the packaging box in the supermarket, and there are obviously rats spending the night here.
Other rats were not so lucky, and they had to run to the trash cans on the street to eat some leftovers. Perhaps it is the harsh environment and lack of food, this part of the mouse hair is hard, like a hedgehog straight out, and this part of the mouse, seeing the cat and dog is not very afraid, from time to time tilting its head to stare at them!
Why are there so many rats in Britain? There's a lot of articles in it!
Britain's special geographical environment provides a natural breeding ground for rat reproduction, which has led to centuries of fighting with rats in Britain. The first plague broke out in England in 1348 and did not end until 1679, killing more than one-third of the population in 300 years, and spreading throughout Europe, killing 25 million people.
After the rise of the British Industrial Revolution, especially after the Second Industrial Revolution, a large amount of chemical sewage was discharged into rivers and lakes, and these rats gradually mutated after eating poisonous food. An official British research institute has captured mice in more than a dozen regions of the country, and the results show that 75% of mice contain drug resistance genes. These resistance genes also vary in strength depending on the distribution area of mice: rats near large cities are more resistant to drugs; rats clustered in remote suburbs are less resistant to drugs.
What is more worrying is that the genes that inhibit growth and reproduction in these mice do not seem to be very "bright", resulting in a series of record giant mice over the years. According to an impromptu report, the average size of British rats has increased by more than 30% compared to hundreds of years ago. Of course, this cannot be imposed on genetic mutations, and the current supply of sufficient food is also one of the important reasons. Some time ago, the British media broke out that more than 100,000 pigs will be buried due to the lack of butchers! The question is, are there any dead pigs that have been torn and eaten by rats for various reasons? It's all worth studying!
The "sudden rise" of British rats in 2020-2021 is inseparable from the raging new crown pneumonia. The lockdown measures taken by the United Kingdom due to the new crown epidemic have created a "perfect invasion condition" for rats: the original crowded supermarkets, small shops, and wet markets are suddenly empty, and rats have changed from cautious to bold, and the range of activities has increased and food has become abundant - they do not mate, breed strangely!
In fact, as early as the beginning of 2020, a pest control agency in the United Kingdom issued an early warning that it should be vigilant against the spread of rats during the epidemic period, and recommended that residents take precautions. For residents, at most, add some skids to the house, buy some rat poison, and there is no other way. These measures have done little for hundreds of millions of rats. A grandmother in England installed a new toilet, and later always smelled the odor, and finally found a dead rat in the water bend under the toilet, the rat tried to break into the house through the sewer, did not want to die here, until 6 months later was found.
Experts said that the United Kingdom really wants to control the rat plague, first clean up the sewers and garbage cans in various cities. British underground pipelines as early as the 50s and 60s of the last century has been basically formed, according to the survey of that year, there are 2,000 rats per square kilometer of sewers, and the entire London sewers have 16,000 square kilometers, not to mention that now it has become more complex and the environment is harsh!
