The existence of humans on Earth has been relatively short when compared to the planet's history. However, for centuries, scientists, philosophers, and futurists have wondered: when will the end of our species come?

Natural causes that could lead to human extinction:
Nature has always been a powerful and unpredictable force. Some natural events that could lead to the disappearance of humanity include:

Asteroid impact: Large space rocks have hit Earth in the past and could do so again. A large enough asteroid could trigger a global winter and destroy entire ecosystems.

Supervolcanoes: A massive eruption like the one expected from Yellowstone could release vast amounts of ash and gases, blocking sunlight and causing global climate collapse.

Extreme cooling or warming: Severe climate changes, whether naturally occurring or human-induced, could make large areas of the planet uninhabitable.

L’espèce humaine : notre fin sera-t-elle inévitable ?

Human-made threats:
Human intelligence has brought progress, but also unprecedented dangers.

Nuclear war: A global conflict using nuclear weapons could kill millions within minutes and leave radioactive consequences for centuries.

Environmental collapse: Deforestation, biodiversity loss, pollution, and climate change are weakening the natural systems we depend on to survive.

Uncontrolled or engineered pandemics: Viruses deadlier than COVID-19 could spread rapidly if not detected and contained in time.

Uncontrolled technological advances:
Technology is a double-edged sword. Without ethical and responsible management, it could turn against its own creators.

Out-of-control Artificial Intelligence: An AI system with poorly defined goals could make dangerous decisions or even eliminate humans if seen as a threat.

Biotechnology and biological weapons: Access to genetic technologies makes it possible to create modified organisms that could cause devastating effects if misused.

When will humans cease to exist?

There is no exact date, but experts agree that the next one to five hundred years will be decisive. If humanity can overcome its internal and external threats, it could survive for thousands or even millions of years.

Some futurists believe our species will evolve into another form, such as a combination of biology and machines, or migrate to other planets to ensure survival.

Human extinction is not inevitable, but it's not impossible either. Everything will depend on the decisions we make as a civilization in the coming decades. Prevention, adaptation, and global responsibility are key to ensuring a long-lasting future for our species.
