How long can humans survive on earth? This is a question that many of us want to know, and i believe that we do not want to wake up to a "Purgatory" Like venus, and hope that the earth can remain alive forever, so that we humans can continue and our generations can survive on earth forever. If the earth's environment were to change drastically and become an extremely hot planet like venus or mercury, then naturally everything in the world, including humans, would not be able to exist.

Mount fuji, located in the south of honshu island in japan, is a famous active volcano, with an altitude of about 3,775 metres, and is the highest peak in japan, so it has a very important symbolic status in japan. From the viewpoint of its appearance, mount fuji is still quite different from many other mountains, and when viewed from afar, it looks like an upside down fan hanging in the air.
