Ecosystems are powered by light energy. Without the sun, ecosystems would be destroyed due to lack of energy and all living things would die in a short time. Therefore, some people believe that the Earth was once affected by comets, and the flying dust covered the Earth's surface for a long time, isolating the light energy, so the species became extinct. If there was no sun, it is obvious that. there would be no sunlight to shine on the earth, so the earth would become On a frozen planet, all living species would not be able to survive. Of course, humans would die on a massive scale, because as long as there are. if there is no sun, all living things on earth will disappear.
So, as the current human technological level loses its luster, can a small part of human beings continue to survive? This is a problemvery difficult. First, it depends on how humans obtain energy and resources without sunlight. Today, most of the resources available to humans come from the sun, such as electricity. Without sunlight, solar power plants and hydroelectric plants (where water forms ice) cannot operate. The only ones that function properly are nuclear power plants, but the energy created by nuclear power plants might not be able to support the proper functioning of a small-scale ecosystem.
If there is no such ecosystem, even if a few people can persist for a while, they will probably perish eventually. Sunlight on Earth comes from the sun. Without the sun, the earth would be plunged into darkness. The Earth freezes: Without the sun, the temperature of the Earth's surface drops rapidly, the waters freeze, and the final temperature drops jdown to approximately minus 200°C. Leaving the solar system: The Sun is the star of the solar system. If the sun disappeared, its gravitational field would disappear. Stars in the solar system will leave the solar system due to inertia.
If there was no sun, there would be no sun to shine on the earth. Obviously, the earth will become a frozen planet and all living species will be unable to survive. If there is a shortage of energy and resources, humans will also die on a large scale. This is the most direct impact, because as long as there will be. If there is no sun, all living species on earth will be threatened with extinction. How to get energy and resources, now most of the resources humans can use come from the sun, like electricity. If there is no sun, solar and hydroelectric plants (the water will form ice) will not be able tofunction. The only ones that can operate normally are nuclear power plants, but nuclear power plants do not necessarily create energy to support the normal functioning of a small-scale ecosystem. Without such an ecosystem, a few people may persist for a while, but can do so. finally perish.
Animals and plants commonly known to men must be condemned? Because they got used to life with the sun? It is impossible for them to evolve with functions that do not require the sun? sunlight for a short period of time?
Creatures in deep-sea volcanic vents rely on chemicals and heat emitted by volcanoes to survive and have evolved unique functions?
Earth cannot survive only from the seabed. Start evolution again after hundreds of millions of years? Maybe we canire evolving advanced developments?
