These 7 Frightening Things Might Actually End the World, Scientists Say

Who or what will end the world as we know it? Will be sooner than expected? 

When did nuclear war seem so unlikely to happen? Seems like a million years ago and the fact that it no longer does demonstrates how swiftly dangers to humankind may evolve and how crucial it is to take everything seriously.

Chemical warfare, asteroid collisions, supervolcanic eruptions, and the impending consequences of climate change pose a danger to anything from the fall of civilizations to the extinction of humans.

Now, with these dangers in mind, we can easily picture something similar to what happened in the Mad Max franchise and fantasize about how bad it will be. But no more of this; let’s start with the number one threat that can easily end the world as we know it, according to scientists:

1. Ecological collapse

One of the first calamities that can end the world is an ecological collapse. Ecosystems are fragile communities of living things, including people and animals, that interact with the nonliving elements of their surroundings, such as the air and water.

There is a point in time at which ecosystems can no longer withstand the effects of human activity, such as habitat loss or temperature rises, and the research suggests that we may be approaching that threshold.

Can a drought end the world? Well, let’s discuss, for example, Lake Chad, located in West Africa. This is the best example of an ecological collapse. The lake has decreased by 90% as a result of 60 years of drought, excessive water consumption, and the effects of climate change. The lives of almost 40 million people who depend on it in Chad, Nigeria, Niger, and Cameroon have been severely impacted by its drastic depletion.

Who is really to blame for the end of the world? Well, humans are the primary change agents, the ones who are really changing everything and contributing to the overall damage to the ecosystem.

2. Robots taking over the world

Technology helped us in so many ways; that’s why there is doubt it helped us get so far. But at what cost? A lot of video games and movies depict various scenarios in which androids will end the world, and none of them is a happy one. But realistically speaking, there is no chance that AI will become malevolent.

Scientists estimate that by 2050, there is a 50% possibility that artificial intelligence (AI) will be as good as or better than humans in performing the majority of activities that humans do now. Maybe AI will not end the world; putting AI weapons in the hands of the wrong individuals will.

3. Nuclear war

One thing is certain: nuclear war is going to end the world! Other dangerous things mentioned above may be easily avoided—not entirely, but still, we can’t escape from a nuclear war. In the 4 km-radius blast zone, a nuclear explosion from one of today’s most potent weapons would result in an 80–95% death rate, but “severe damage” may spread six times as far.

However, we should be more concerned about the nuclear winter than about mortality rates. At this point, the earth is covered in clouds of smoke and dust that obstruct the sun, perhaps resulting in a prolonged period of low temperatures.

A nuclear war between the US and Russia, who own the great bulk of the world’s arsenal, might result in the detonation of 4,000 warheads, which would result in an unknown number of deaths and an 8-degree Celsius reduction in global temperatures for four to five years.

Anarchy and bloodshed would break out if humans were unable to produce food. Remember that Mad Max scenario I was talking about? This is going to be the same. The worrying thought is that nuclear weapons can be released at any time and end the world in a matter of seconds…

4. Global epidemics

Back in the day, in 2020, we were all petrified about COVID-19. There was no cure for it; medical personnel didn’t know much about it, and this caused a huge panic worldwide. Can you imagine going through something similar again? If not we, our grandchildren and grand-grandchildren will do.

The Black Plague, which almost killed the world in the fourteenth century, has been a topic of conversation once more in recent months. Does anyone recall the cholera outbreak? or the measles?
The most terrifying scenario, according to several experts, would be the introduction of a strain that transmits so quickly that we are unprepared for it or that defies all chemical containment techniques, maybe as a result of human disturbance of the ecological balance.

Luckily, deadly diseases are pretty rare, but there is always a huge possibility for them to end the world. However, we must still try to develop new, stronger antibiotics by 2050 to be able to fight against various types of resistant bacteria.

5. Volcanic eruptions

Another one on the list of frightening things that might end the world is volcanic eruptions. A big volcanic eruption can happen every 17,000 years, and if that’s the case, we’re past due—the last one we know of occurred in New Zealand 26,500 years ago.

On the other hand, neither scientist can predict when the next eruption will occur or how to lessen the chance that it will. However, one thing is certain: experts are keeping an eye on many dangerous regions, including Yellowstone in the United States.

6. Change of climate (global warming)

The fact that the Earth is warming steadily every day is not surprising at all, and although we may not like to hear it, we are somewhat to blame. A warmer Earth may also help spread infectious diseases by giving parasites a better environment and expanding the spectrum of tropical infections, according to researchers like Harvard Medical School’s Paul Epstein, who has expressed concern about this hypothesis more recently.

These are regrettably really bad news since they might have a severe impact on agriculture, leading to starvation in the end. Earth may ultimately resemble Venus, where the average daily high is 900 degrees Fahrenheit.

7. Asteroids hitting the Earth

The last, but not least, of the multiple causes that can end the world, are asteroids. However, what are the chances that this will occur soon? Yes, one asteroid is big enough to bring about a worldwide disaster, but it takes place once every 120,000 years.

Now, NASA declared a couple of years ago that it had mapped over 90% of space objects with a diameter of one kilometer or more and that none of them were likely to collide with Earth. Pfew good news! That means we can breathe a sigh of relief! However, if not a big asteroid, there are still many other small objects that can damage our planet in a matter of seconds.
