How long will there be life on Earth?

The authors of this study estimate that the total habitable lifetime of Earth – before it loses its surface water – is around 7.2 billion years, but they also calculate that an oxygen-rich atmosphere may only be present for around 20%–30% of that time.

What year will the Earth explode?

End of the Sun Gamma-ray burst or not, in about a billion years, most life on Earth will eventually die anyway due to a lack of oxygen.

What is the maximum population the Earth can sustain?

Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people. One such scientist, the eminent Harvard University sociobiologist Edward O. Wilson, bases his estimate on calculations of the Earth’s available resources.

What year will we run out of food?

According to Professor Cribb, shortages of water, land, and energy combined with the increased demand from population and economic growth, will create a global food shortage around 2050.

How long will it take for humans to go extinct?

7,800,000 years
Humanity has a 95% probability of being extinct in 7,800,000 years, according to J. Richard Gott’s formulation of the controversial Doomsday argument, which argues that we have probably already lived through half the duration of human history.

What would happen if Earth ran out of water?

Due to their large surface area, they lose a lot of water to evaporation. If this happened, it wouldn’t take long for the common water supply to become unsanitary under these conditions. The polluted water supply would kill aquatic life, further reducing the available food supply.

What would happen if we ran out of food?

Like trees, plants feed us and give us the oxygen we breathe—and if they were to run out, humans and animals would starve and suffocate. According to New Scientist, oxygen would remain in the atmosphere for quite a while, but we would run out of food long before we’d run out of air.
