I don't know what you mean so i will assume that you mean: Will humans ever have to evacuate the earth?
I personally think that in 5000 years or so, the Earth would've been worn out by greenhouse gases and oil would be depleted. This moment of crisis will send the earths officials into a nightmare that will make them think about civilizing other planets. By then i suppose we would have found other planets with the right temperatures and pressure to stay alive. Answering your question, yes- I do think that we will have to evacuate the earth. Not in our lifetimes though!
That depends on who you ask. Pluto technically has the longest year; each Plutonian year is equal to 247.7 Earth years. However, some scientists no longer consider Pluto to be a planet, and call it a "dwarf planet" instead. Since this decision was not actually binding, many people (including scientists) still consider Pluto a planet. If Pluto isn't actually a planet, then Neptune is the planet with the longest year (164.79 Earth years)
If the estimated size of the universe is correct and that planetary bodies circle most stars then it is approximately 13.5 billion light years away.
It is possible, with many years left in human life, we should eventually have the technology to do it. For now if we make it to mars, we could plant a plant off ofMars' soil (because there is an extreme toxin in it) to oxidize the planet.
Many people today assume mistakenly that the Earth is so big that we humans cannot possibly have any major impact on the way our planet's ecological system operates.
It is the hottest planet, and it is very rocky with many craters. It is terrestial and the closest to the sun and also the smallest planet.
A lot of people. There are an estimated 6.6 billion humans on planet Earth.
Only the Planet Earth have humans walked on.
As of 2013, Pluto has been classed as a dwarf planet for 7 years.
1,789 years
About 4.5 billion years.
There is no definitive timeline for humans to leave Earth. While there are plans to establish colonies on other celestial bodies in the future, such as Mars, the technology and resources required for sustained human habitation beyond Earth are still being developed. It is likely to be many years or decades before humans permanently leave Earth.
I'm not aware that anyone is worried about ancient forests, but there are many scientists who would like to know more about those ancient forests and their environments millions of years ago. By studying the history of our planet, we can get clues about the future of our planet.
