Dinosaurs are the "Big Mac" species on the earth and should have strong vitality. But it was extinct a long time ago. Now all we can see are dinosaur fossils and models. Many scientists in the world want to find out the reason of dinosaur extinction through the clues left by dinosaurs. But the extinction of dinosaurs remains a mystery.
Some scientists believe that dinosaurs were poisoned by eating poisonous flowers and plants:/kloc-0.2 billion years ago, some flowering plants often contained strong alkaloids, and some alkaloids were very toxic. After dinosaurs ate a lot of alkaloids, the toxin reaction led to serious physiological disorder and death. Some scientists believe that the extinction of dinosaurs was caused by volcanic eruption caused by asteroid impact: about 65 million years ago, a huge asteroid or comet fell from the sky and hit the earth at a speed exceeding 10 km per second. The powerful explosion shock wave swept half the earth, and most dinosaurs were wiped out. After the shock wave, the global fire and high temperature caused by the explosion caused some dinosaurs to be burned and roasted to death. Later, the temperature plummeted and acid rain got wet. This extremely harsh environment buried the last dinosaur.
No matter what causes the extinction of dinosaurs, the principle is the same, that is, the living environment has changed greatly, and it is no longer suitable for dinosaurs to survive, which eventually leads to the extinction of dinosaurs. The extinction of dinosaurs reminds us of the extinction of other species on earth. Why not? With the continuous destruction of the earth's environment, floods, earthquakes, tsunamis and other natural disasters occur frequently, and the human living environment is facing serious threats. If it is not stopped and protected, human beings will end up like dinosaurs. Therefore, we should strive to protect the environment, green the environment, do not cut down trees indiscriminately, do not dump garbage indiscriminately, do not discharge pollutants indiscriminately, and do not waste the earth's resources, so as to create a beautiful living environment for future generations and prevent mankind from repeating the mistake of dinosaur extinction.
