Strange things always happen in the mysterious natural world, have you ever experienced a good little park turning into an ice sculpture overnight? Have you ever seen the whole city where you live turn orange-red? And this and so on and so forth, and so on

Let's go with the narrator, this is a small town in Switzerland, where people live a happy and comfortable life. On weekdays, walking cats and dogs raise flowers, fishing is not comfortable, summer here is a pastoral scenery, spring here is a tourist resort, but in a winter morning, when people open their eyes from sleep, only to find that the town they live in is all frozen by ice
Overnight it all turned into ice sculptures according to one memoir describing all of the day. My things were wrapped in a layer of ice up to 10 centimeters thick, their dogs were sliding around on the ground, and some people who were eager to go to work even tried to rescue their cars with knives and axes, but it was impossible to succeed, what happened to cause this town to turn into ice sculptures overnight?
Through the analysis of meteorologists, it was found that it was related to the weather in their place, the temperature of the town at night was about minus 10 degrees, so it was not uncommon for the lake to be frozen, but it was rare to encounter a rare wind on the lake that night, and the huge waves swept by the wind hit the southwest corner of the dock, and in the low temperature of minus 10 degrees, all the places hit by the huge waves became magical ice sculptures, and the ice began to melt after a whole week.
A very strange thing happened to Sydney, Australia's largest city, which also surprised the whole world, because it changed a color overnight, and when the first light of the morning sprinkled on the earth, people were surprised to find that their eyes were all soaked with red, and everything seemed to be covered with red. Residents have picked up cameras and mobile phones to record this strange scenery, what is the reason why such a large city has been shrouded in red overnight, becoming like the surface of Mars?
In fact, the answer is located 2500 kilometers away from Sydney, where the dust is dark red all year round because of its rich iron element, by asking the residents here, according to his description, the bearded grandfather indicated that on the first day of the incident, the car he drove would be overturned by a sandstorm, like a sword and dust hit his car, he said that he had never seen such a large sandstorm.
To prove his claim, Grandpa Beard drove his scientists on the road chasing the departing killer. It looked like a mountain and pushed forward slowly, just entering the sandstorm was like entering a room without lights, and all that could be seen was a little bit of oppression in front of it, and the red morning in Sydney was the scene left by the sandstorm
When you encounter a rat, you should be able to cope, but what about a group of rats?
In the Australian farm, there is a farmer vs. rat, and tens of thousands of hungry rats are desperately trying to eat the pigs surrounded by the railing, which happened 20 years ago, if it is a little far away.
In the face of farmers who attacked Australian farms again 10 years ago, this year's harvest year. Can't see the happy expression, because in their farms not only have livestock, but also think of millions of rats, don't look at their size, like they can eat tons of grain every day, these are equivalent to a family's rations for 10 years, but the farmers in order to eliminate these rats are also exhausted to hit and catch, etc. It is not helpful, because rats can produce about 6 in three weeks, a bunch of mice, can not be solved at all, here the farmers have a big headache, Why is there such a serious disaster as rat infestation?
In fact, it is mainly because rats are invasive species in Australia, they were introduced by Europeans in the 18th century, and there are no natural predators to hunt them in australia, which is abundant, and there is no direct competition from local wildlife. This also provides conditions for the reproduction and survival of rats, which are unstoppable.
