Can you think if one day earth destroys totally then what human do?

how they survive? how can they save the human & another species?

what can they do on another planet? if possible

So let's know

Apart from the Solar System, Earth is the only planet in the known universe that has ideal conditions for life. Our astronomers are engaged in the search for planets where there may be room for life beyond Earth, which they call extraterrestrials. Meanwhile, looking at climate change and other problems on Earth, it seems that soon the Earth may not be capable of living for humans, so the option of making another planet friendly to life is also being considered, but it is possible to.

The planetary science of changing a planet to make it habitable is called terraforming. Mars and Venus are the planets similar to Earth in our solar system. Mars is far from the Sun and Venus is near the Sun. Both the planets are also quite different from Earth. The main difference between them is that of the atmosphere. Both do not have an oxygen-rich atmosphere.

Mars is considered more suitable for terraforming than Venus and Mars, but the atmosphere of Mars is mostly carbon dioxide and this atmosphere is very thin. There is no atmospheric pressure like Earth, which can maintain liquid water. At the same time, all the water on the surface of Mars is in the form of ice and a very small amount of steam in the atmosphere.

The average temperature of Mars is also -60 degree centigrade. For this, such a system will have to be made to keep the heat in its atmosphere. Here we have to add even more carbon dioxide and methane for the greenhouse effect. Due to this, Mars will warm and ice will melt, which will create a water cycle like Earth's climate. And due to the seasonal changes of Mars, there should be rain too.

Perhaps this is the reason why instead of changing a planet through terraforming, a colony should be created in space where an ecosystem can survive and many forms of life can survive. Apart from this, if we find a planet like Earth in any other solar system, we can try to go there too. But at the moment we are not able to do this. Right now it would be best that we can reduce the human impact on the earth as much as possible.

so what do you think about terraforming?

Is it possible in the future?
