To live or to die, that is the question. On the earth, we are faced with the reproduction, continuation and death of life, and a new beginning. This cycle of life process, in this process, we see more awe of life.
6 continents, 45 countries, 195 places, from underground caves to space stations, from Russia's Kamchatka Peninsula, Iceland's Vatnajökull Glacier, New Mexico's Tequila Cave, China's Yellow River Xiaolangdi and other regions, each location has its own The secret places of life, every place, are revealing to us the origin, development and meaning of life.
"Survival" and "how to survive better" have become issues worthy of our deep consideration. Astronaut Jerry Linenger first shared a thrilling memory with the audience. On one occasion, a solid-state oxygen cylinder on the space station exploded, causing an unexpected fire that expanded rapidly and could damage the interior of the space station at any time. At this critical moment, Jerry desperately extinguished the fire. At that moment, he finally understood that survival is the instinct of all life, and all living individuals should be in awe of death.
In fact, in addition to danger, aging, disease, accidents, etc. that will kill you, the earth will also end life. The earth has experienced 5 mass extinctions before, and 99.9% of the species that have existed so far have disappeared. In the process, along with the eruption of many super volcanoes, the land dried up, the ocean acidified, and almost all animals and plants were wiped out, turning the earth into the largest mass murder scene in history.
In order to cope with unknown dangers, all organisms are multiplying to make their populations more adaptable to changing environments. Corals on the seafloor are a typical case. By mating, they improve the chances of mixing genes, making the next generation of corals more diverse, and have survived in complex marine environments for up to 250 million years.
At the scene of a fire in Lake County, Calif., firefighters are facing the temptation to die. In the face of the huge fire, everyone's eyes, skin and lungs are being tested by the high temperature. But each of them always carried a kind of reverence in their hearts, more of a reverence for life. Because fires will not only burn plants and houses, but also burn dead plants and waste on the ground, allowing new life to grow.
When there is an end to life, the role of mother is better to continue life. Salmon spawned and experienced the journey of life and death. After spawning, the corpse of salmon turned into nourishment, nourished plants, and produced a new continuation of life.
Without death, there would be no life. In the destruction of a planet, or the individual sacrifice that accompanies the better preservation of genes, it is death that promotes evolution. As small as a cell and as large as the contours of the Earth, our colorful and vibrant planet exists only because death brings opportunities for biodiversity and ensures that life will never disappear on Earth.
