Now the earth is adding nearly 80 million people every year,

If you were standing at the equator of the earth when you were 6 years old,

and all 8 year old men and women oh,

Every 1 sed a man and a woman must pass in front of you,

May I ask how old are the men and women who pass by when you are 300 years old?

Bckfoot shook his head,

Bckhead paused and tinued:

Earth's civilization in 7017 AD reach the sed-level stelr civilization,

If humans do not bee extinct within 3 million years,

Then at the time of 3 million years of the earth's Gregorian era,

Humanity will find a p suitable for humaence,

In 1.5 billion years of the earth's Gregorian dar,

The luminosity of the sun will increase a lot, causing the earth's climate to overheat,

Threatening the survival of multicellur anisms, the earth's enviro will be Martianized,
