According to research, the earliest specimen of modern human remains found in Greece is about 210,000 years old. Our planet is approximately 4.5 billion years old. It turns out that people exist only for about 0.004% of the entire lifetime of the Earth.
It seems to us that our history of life is very long, but in fact it takes up much less than 1% of a percent of the entire history of our planet. And even in such a short time, we ourselves have witnessed how the planet is changing.
Take, for example, the history of the Sahara: about 5-7 thousand years ago it was a blooming and green corner, and now it is one of the most dangerous deserts on the planet. Even on the ancient maps of Africa, forests, rivers were depicted in this territory, there were many settlements and large trading cities, but now all these treasures are buried under tons of golden sand.
If such changes can occur in such a relatively short period of time, then what will happen to the planet in the distant future? We will be optimists and imagine that humanity does not self-destruct and will continue its life on the Blue Planet.
In the tenth millennium
We will cease to be unique, as we are now: humanity will lose variations according to the genetic principle, and everyone will be similar to each other. Now someone has light skin, someone is dark, different colors of eyes and hair, different facial features, but in the future we all “will mix with each other” so much that we will become a single human race. Perhaps we will even have one common language – the only one on the entire planet.
It turns out interestingly: once our ancient ancestors were similar to each other, but settling on different continents made us different depending on where we lived. In the future, we will again become almost the same.
It is also possible that If people achieve genetic uniformity, they will simply degenerate under the influence of inbred depression. There will remain a handful of survivors in different parts of the earth, which will again begin to change under the influence of the environment. And again, racial and genetic diversity will arise. Unless, of course, at least someone survives.
There is a biological aspect we need to take into account. We will not have enough resources of the planet in the form of oil, gas and other hydrocarbons in the next 200 years, or even less. Nuclear energy and renewable energy resources in the form of hydroelectric power plants and wind turbines will also not be able to answer the energy demands of civilization in about 50 years. Then the “bacterium-antibiotic” race in favor of bacteria will run out of steam.
By the twentieth millennium
A common language, according to forecasts of scientists, will be formed, and even if a modern person, who speaks several languages, moves into the twentieth millennium, he practically will not understand anything from the speech of the people of the future.
Presently, we should consider ourselves lucky: the planet has a comfortable and warm climate, but this will not always be so. In the history of the Earth, there were cyclical periods of glaciation, during which glaciers covered almost the entire planet up to the equatorial zones, respectively, it was possible to hide from the cold only there, or under water next to hydrothermal springs.
Most living creatures could not withstand such changes and died from the cold and lack of food. Such glaciation occurs due to astronomical factors combined with climatic feedback mechanisms and plate tectonics.
At the moment, the Earth is in the interglacial epoch, which is supposed to be completed in 25 thousand years. However, vigorous human activity, during which the greenhouse effect is created, may even save the planet from glaciation for some time and delay the beginning of the next ice age by at least 50,000-130,000 years.
But the ice will still take its toll, since fossil fuels will run out already in about 2200, and when the composition of the atmosphere changes again, you will have to get fur coats and hats.
In 100,000 years
Changes in the starry sky will no longer be insignificant, but dramatic – you would not find a single familiar constellation, and even the famous “Big Dipper”.
After 500,000 years
Mankind will still get to the Red Planet and by that time will be able to finally “tame” it so much that it will be possible to walk on its surface without space suits and even breathing apparatus.
During this period of time, most likely, according to statistics, a large meteorite will collide with the Earth, and the catastrophe may be the same in scale as 65 million years ago, so the future of our home is in the hands of people.
By that time, the life expectancy of people will have increased significantly, and a person is unlikely to be the same as now. Technology will literally become a part of us.
In a million years
It is likely that, people will begin to explore other star systems and settle on different planets. Guess what will happen? We will have racial differences again!
What will happen to the Earth? Everything will depend on human activity. If people exhaust all its resources and settle in other worlds in search of new habitats, and each race will subsequently have its own new home, then the Earth will “rest”. But its appearance will change beyond recognition.
In 250 million years
There will again be a supercontinent, something like the ancient Pangea.
After about 500 million years
The supercontinent will begin to split up again. But the Earth will not be a Blue Planet for long, therefore, no matter how much we love the Earth, we will have to look for a new home.
After 800 million – 1 billion years, the Sun will increase its luminosity so much that all the water on Earth will evaporate, and only burnt rocks will remain here, a wasteland.
Having given us everything, the Earth will perish by itself – no technology will save it.
In another 4 billion years, when the Sun becomes a red giant, it will absorb Mercury, Venus and, possibly, the Earth, and then, throwing off the outer shells, will also meet its end.
All that will be left of the sun is a tiny white dwarf, which will be only a distant reminder that once under the golden rays of the former star, various civilizations developed, now traveling across the galactic expanses and carefully keeping the history of their home.
