How long is Earth habitable?
This is expected to occur between 1.5 and 4.5 billion years from now. A high obliquity would probably result in dramatic changes in the climate and may destroy the planet’s habitability.
How old is the human race?
about 200,000 years ago
While our ancestors have been around for about six million years, the modern form of humans only evolved about 200,000 years ago. Civilization as we know it is only about 6,000 years old, and industrialization started in the earnest only in the 1800s.
How many people will ever be born?
We also estimate that by 2050 another 4 billion births will increase the number of people who have ever lived on Earth to about 121 billion….TABLE 2. Snapshot of Population History.
| – | – |
|---|---|
| World population in mid-2020 | 7,772,850,162 |

Can We Survive 100 years on Earth?
Hawking explains that humankind’s days on Earth are already numbered because of climate change, asteroid strikes, epidemics, and overpopulation. The only way to survive? We need to change planets, and fast. A lot could happen in 100 years, and we’ve proven that we’re capable of discovering and developing many things within a century.
When will the Earth become uninhabitable?
The evaporation of the Earth’s oceans would be well underway by 1 billion years from now. We can assume that millions of years before this, Earth will have become uninhabitable. Life more complex than a bacterium has only been around for 600 million years, so it looks like we are about half way through the ‘Golden Years’.
What has humanity accomplished in the past 100 years?
Over the past century or so, humanity has accomplished a great deal of innovation. We learned to fly (at least with the help of airplanes), built huge machines, cured diseases, and developed computers, the Internet, and smart devices.
What will happen to the Earth in 300 million years?
In 300 million years or less, it may become very inhospitable for life to continue to exist on the land, and if we leave it alone, evolution may encourage life to return to the sea where the climate will be a bit more moderate. As for humans, we may adapt to living on the land, or we may decide to leave the planet.
