1. Particle experiments can devour the earth
<: < Terrible black hole > >
particle experimental scientists use particle accelerators to make particles reach the speed of light and then collide with each other to study the energy law of the micro-world. Because the matter being studied is so small, human beings may never worry about what threat particles will pose to human beings. Recently, however, some serious scientific reports pointed out that the particle accelerator experiment or relativistic heavy ion collision experiment in Long Island, USA, may produce a miniature black hole, which will slowly devour everything on the earth, including the earth.

It is often reported that the speed of computers has reached hundreds of millions of times per second. Some scientific reports even think that by 2 3, computers or robots will have the same storage capacity and processing speed as human brains, and even can completely replace human thinking. Scientists even predict that even robots in an unconscious state can pose a threat to human beings.
< < Biological and chemical weapons > >
in the 196s, with the invention of antibiotics and anti-viral pathogens, human beings were confident that we had conquered all kinds of infectious diseases forever, and all viruses could be killed by antibiotics. Unfortunately, more viruses began to change their genes to resist the effects of antibiotics. Up to now, the number of viruses that have baffled medical scientists has increased rather than decreased.
Genetic engineering has gone further. Humans can already change organisms by repairing DNA, and use high technology to change the genetic genes of some animals or plants. Artificial chromosomes will soon be used in medicine and agricultural science. However, these well-intentioned genetic technologies may also bring an unexpected disaster. Humans may think that they are operating a friendly biological gene, but they may destroy crops, animals and even humans in some unexpected way.
The biological and chemical weapons virus is one of the biggest threats to human beings. It was difficult to manufacture before, but some information about the manufacture of biological and chemical viruses on the Internet now makes it very easy.

V. Supervolcano eruption
<; < Volcanic eruption > >
There have been at least six devastating volcanic eruptions on the earth. Compared with these super volcanic eruptions, Mount Etna in Italy is only a child's play. In his book Towards the End of the World, Bill McGonagall, a professor of geophysics at University College London, believes that it is only a matter of time before the next super volcano erupts.

VI. Earthquakes trigger world economic crisis
Great earthquakes can even change the rotation speed of the earth
Humans cannot predict whether there will be another Tokyo earthquake like that in 1923. In the epicenter of that site, 2, people died and the economic loss reached 5 billion dollars. Scientists estimate that if mankind suffers another Tokyo earthquake similar to that in 1923, the world stock market will dive freely and the European and American economies will collapse completely.
7. The probability of an asteroid crashing into the earth is greater than the first prize in the lottery.
Dinosaurs may be extinct because of an asteroid crashing into the earth.
In the past history of the earth, they have been hit by asteroids or comets from outer space many times, but these whispers can't do great harm to the earth because of their small size. However, scientists believe that an asteroid with a diameter of more than 15 feet will be a human disaster if it hits the earth. If an asteroid this big hits London, it will destroy the whole Europe. Through calculation, scientists believe that an asteroid with a diameter of 1 km will hit the earth every 1 thousand years, and an extraterrestrial object of this size will cause a global ecological disaster. And an extraterrestrial object with a diameter of 1 kilometers will level the earth and make the earth reproduce the disaster of dinosaur extinction 65 million years ago. According to the research of Professor Duken Steele in university of salford, England, about 1,5 asteroids with a diameter of 1 km have passed or are passing through the earth's orbit.
VIII. The greenhouse effect of the burning earth is becoming increasingly obvious
Will the scene of the movie After Tomorrow really come?
In the past century, the temperature of the earth rose by .6 degrees Celsius, which directly led to the multiplication of various natural disasters caused by storms, floods and droughts. According to statistics, the number of natural disasters on the earth in 2 was twice that in 199 6. Scientists predict that these disasters will increase by six times in the 21st century. The latest scientific research results prove that the Arctic Ocean ice is melting in large quantities this summer, which will accelerate the global warming and make future human beings "gradually die" in the heat wave of greenhouse effect.
