Because of Time Travel by the Galactic Time Guard and Time agents connected with the United Nations earth keeps going for millions of years

However, it is also somewhat inevitable that 7 billion people will be gone from the population of earth by 2100AD with more or less 1 billion left possibly. The reason for this is likely the fault of all our ancestors and people around the world having more babies than Earth could sustain. When we went past 1 billion people in the early 1800s on earth we were already past what the surface of earth could sustain (if we lived on the surface of the earth and not under the earth. I'm thinking that somewhere between 13 and 15 billion people could be sustainable if all cities and homes on the surface were torn down and all that land that was usable became farmland or recreation areas however. But, the problem would be that humans could not or would not agree to this so I"m thinking that the 1 billion people more or less is all that will be left on earth by 2100AD.

Contrary to popular belief it will not be wars that kill most people. It will be things like Covid and Global Climate changes which are both a part of the same thing if you look at it scientifically.

Diseases like Covid happen because of species going extinct and those species are then often replaced by other species that carry diseases and then you have plagues as those disease spread.

So, likely for every species extinction caused by human population, thousands of human beings as well as thousands to millions of other individuals from species all over the earth will perish.

So, I think people need to prepare for what this century likely will bring to everyone ongoing.

Will technology and better education help? Yes. A lot. But, remember the majority of people on earth won't be educated enough to make a difference in their lives. So, I would say about 1/3 of the people on earth can really benefit from most technological changes that will save their lives.

Some of the things that will benefit everyone:

Houses made of metal and concrete that can withstand 300 plus mile per hour winds with steel shutters that can be closed so windows won't be blown out. Making these homes dome shaped might also lessen the effects of high winds over 300 mph at times during the year most places on earth.

By the end of this century it is likely that all wooden structures on earth will have been blown down (more or less) in winds over 200 to 300 miles per hour. Of course this depends upon where those structures are on earth and what the winds are like there year around.
