Human extinction is the hypothetical end of the human species due to either natural causes such as population decline due to sub-replacement fertility, an asteroid impact or large-scale volcanism, or anthropogenic (human) causes, also known as omnicide.
How mankind is driving the next mass extinction?
The study states that this mass extinction differs from previous ones because it is entirely driven by human activity through changes in land use, climate, pollution, hunting, fishing and poaching. The effects of the loss of these large predators can be seen in the oceans and on land.
How are humans causing the sixth mass extinction?
Other, related human causes of the extinction event include deforestation, hunting, pollution, the introduction in various regions of non-native species, and the widespread transmission of infectious diseases spread through livestock and crops.
What is the biggest threat to humanity today?

|---|---|
| All wars (including civil wars) | 4\% |
| Engineered pandemic | 2\% |
| Nuclear war | 1\% |
What is known as Sixth extinction?
The sixth, which is ongoing, is referred to as the Anthropocene extinction. These extinctions were caused by “catastrophic alterations” to the environment, such as massive volcanic eruptions, depletion of oceanic oxygen or collision with an asteroid.
Can humans survive mass extinction?
We’re so uniquely adaptable, we might even survive a mass extinction event. Given a decade of warning before an asteroid strike, humans could probably stockpile enough food to survive years of cold and darkness, saving much or most of the population.
