End of the World Scenarios

Asteroid Impact

One theory about how our planet came into existence is that a large asteroid collided with Earth in its early days. If another asteroid were to hit us in modern times, we would have no chance against it. If this happens, the only thing you can do is hope for a quick death or pray for God’s mercy on your soul!

The impact would throw debris into the atmosphere blocking out light, heat, and oxygen. The temperature on Earth’s surface could drop to below freezing, killing plants in a matter of minutes.

Ice Age (hyperborean theory)

The Ice Age (also known as the “Hyperborean theory”) is the end of the world theory that states that the Earth is presently in an ice age that will eventually result in an absolute cold.

Several theories suggest that the Earth is in an ice age that eventually results in an absolute cold. One popular idea is that there were four periods of time when glaciers covered the Earthirst period, known as the Huronian Ice Age, which occurred around 2.4 billion years ago and lasted 100 million years.

The second, the Azolla Event, took place approximately 550–600 million years ago and lasted for 50 to 80 million years. The third event, called the Makganyene Ice Age, took place 300-400 million years ago. Since no major glacial deposits have been found from this event, it may well have consisted of a series of brief episodes rather than one single episode lasting millions of years.

Volcanic Winter (volcanic eruptions)

The volcanic winter theory posits that global cooling and other climatic changes following the eruption of a supervolcano could trigger an ice age. The last time such a catastrophe occurred was during the Toba eruption in Indonesia about 74,000 years ago.

The Toba super-eruption caused reduced sunlight because of aerosols in the stratosphere, lowering temperatures globally by 3-5 degrees Celsius for several years. This is comparable to the cooling following significant explosive volcanic eruptions such as Krakatoa in 1883 and Mount Pinatubo in 1991.

A large volume of particulate matter was pushed into the upper atmosphere, but this layer gradually settled over India and China after one year because of their high altitudes.

Zombie Apocalypse

The Zombie Apocalypse is one of the most popular and widely discussed ends of the world theories. Some believe that a zombie apocalypse could happen due to an unknown pathogen or virus. Still, it may also be caused by an electromagnetic pulse or another natural disaster such as an asteroid impact. This event would be followed by chaos and panic, as well as a general breakdown in society. The zombies will cause widespread fear and panic among people.

There is debate about whether zombies are real or not, but many believe that they could happen because we don’t know what lurks inside our Earth (e.g., what animals and insects might be lurking).

The word “zombie” is often used to metaphor various phenomena such as brainwashed people, human bodies deprived of souls, and the walking dead.

According to experts, if there were ever a zombie apocalypse, it would be possible that government and military might use weaponized diseases to attack the enemy population with bio-weapons. Experts theorize that this could give rise to a real-life virus that turns humans into zombies. And this information comes from an FBI agent! People who do not die from attacks from these biological weapons or those who are not turned into zombies will have no idea what they should do next.

In addition, most cities would be invaded by large numbers of zombies easily because many buildings wouldn’t provide any shelter from the infection and the undead (e.g., prisons). As such, zombies would easily overpopulate cities and destroy any supplies that humans could use to survive.

Supervolcano Eruption

In the scenario of a supervolcano eruption, there is a significant production of ash and sulfur dioxide in the atmosphere.

  • This can be fed by a combination of gas and magma in the volcano.
  • The level of particulates in the atmosphere is enough to block out all or most sunlight from entering the Earth’s atmosphere.
  • This is known as a volcanic winter.

In the past, global temperatures have dropped significantly due to this scenario. There was reduced vegetation which led to a collapse of animal populations that feed on that vegetation. Although global temperatures may lower from this eruption, they would most likely return to what they were before once it eventually dissipates.

The leading cause for concern with the supervolcano eruption is not necessarily the temperature drop but rather what happens after it has stopped erupting.

After all, we are talking about a volcano with an eruption volume of 1,000 cubic kilometers – more than enough to blanket continents in ash and potentially plunge the Earth into another ice age if it remains in for several years or decades.

This is the scenario that is most likely to wipe out a significant number of lives, not necessarily directly because of the eruption but rather all the horrific events that are likely to occur due to it.

The Mauna Loa volcano in Hawaii erupted three times during its history, with each one leading to mass extinction on Earth. The first time they erupted was 2 million years ago, and this led to significant cooling of temperatures around the world which lasted about 200,000 years.

Wind From Sun Flares Pushing Away Ozone Layer

The ozone layer is the region of Earth’s stratosphere that contains relatively high levels of ozone gas; it also absorbs most of the sun’s ultraviolet (UV) radiation. The depletion of this ozone layer will lead to skin cancer, cataracts, and other medical conditions.

  • An ozone layer is a layer of the atmosphere made up of molecules, primarily O3, which can absorb solar UV radiation.
  • A current concern for this layer is depletion.

This has been attributed to the rise in levels of certain substances that destroy ozone molecules. The wind from sun flares would cause the Ozone Layer to be pushed away, allowing more pollution to enter the Earth’s atmosphere and its surface.

Nuclear War

In a nuclear war scenario, there would be an intense amount of destruction. All the buildings and structures that were manufactured will be destroyed.

  • All the vegetation that was living on land would be destroyed.
  • The sky would turn pitch-dark due to all the dust in the air.
  • The sun and the stars would not be seen due to all the dust and ash particles in the air.

After nukes detonated on land, this is what it will look like before nuclear winter sets in. Since the bombs have destroyed all vegetation, there is nothing left to filter carbon dioxide from the atmosphere. This leads to massive amounts of carbon dioxide being released into the atmosphere resulting in a greenhouse effect that traps heat near Earth’s surface and rapidly heats up our planet.

After a nuclear bomb detonates on water, it will create a tsunami wave as seen above. This would be the first thing you see if you’re lucky enough to survive all else and be near an ocean when nukes go off. The power from one nuke going off under the sea can kill millions of people from drowning. If you’re not so lucky to survive being caught in the middle of a tsunami wave, then a quickly heating planet or a lack of oxygen is your demise.

Ecological Collapse

The ecological collapse end of the world scenario is where humans have caused the extinction of all life on Earth. Sometime in the future, humans will extract more from nature than they can replenish.

  • This will lead to a global-scale cycling crisis.
  • Eventually, natural resource extraction rates will be greater than natural regeneration rates, and civilizations will crumble owing to environmental factors such as climate change and pollution.

The idea was first proposed by ecologist Eugene F. Stoermer in the 1980s and popularized by environmentalist Paul R. Ehrlich in his book “The Population Bomb” (1968). Ehrlich saw the collapse of civilization due to overpopulation, which he stated is caused by overconsumption. The estimated rate of global human population increase peaked around 1970.

Some proponents argue that if the biosphere reached a “critical state,” depletion would follow, causing eventual devastation to all life forms on Earth, including humans; however, this has not happened yet to any degree worth mentioning; also there are questions about economical ways forward for humanity without using up what only can be found at one place on Earth – its surface.

The environmentalist movement is mainly concerned with man’s destruction of the natural world, which they think could cause a mass extinction. The idea championed by scientists such as Stephen Hawking does not necessarily subscribe to anthropogenic climate change but views humanity as its primary threat.

Economical Disaster

The Economic Disaster end of the world scenario is when a change in the economy causes all marginal workers to lose their jobs instantly.

This would happen when the government was no longer able to regulate, control, and provide for the needs and wants of its citizens, and citizens took matters into their own hands through protest or rebellion.

Once this happens, it is tough to reverse the course of events.

This would be the most significant cause of the Economic disaster end of the world scenario. When people are so hungry, they no longer care about anything else but one day’s food; then there is a high chance that workers will revolt. The government may also collapse due to malfunction, corruption or inefficiency.

This would be an instant economic crash that may produce another type of end-of-the-world scenario. If reserves were low, countries may start trading oil for food instead of money-making other kinds of unaffordable items except for the rich and powerful few which causes civil unrest and revolution throughout all lower-class citizens who cannot afford even one meal per day.

This means that the rich and powerful would control all the food and water supplies since they own most of the farmland, leading to death, famine, and disease for those who cannot afford these life essentials.

Another effect is that there is no one to harvest crops or deliver goods due to a lack of workers. This leads to starvation as those people would not be able to sustain themselves and also means that the government has no revenue coming in from taxes which means that there is no money left with anyone to do anything like pay soldiers meaning that law and order breaks down leading citizens into a state anarchy which leads society into social disorder.

Economic disaster end-of-the-world scenario can also happen if machines replace most such as driverless cars, delivery drones, robots that can serve tables in restaurants or clean other people’s houses, leaving all the people unemployed who would have worked in these areas. This means there is no money coming into the government, which means the government cannot provide for its citizens leading to civil unrest and even revolution where citizens violence against one another trying to get food, water, land, etc.

Global Pandemic

Pandemic end of the world scenarios are kinds of scenarios for apocalyptic and post-apocalyptic fiction, including, but are not limited to, viral pandemics. The pandemic is often a zombie apocalypse. The metaphor is often used in fictional media as a kind of cataclysm.

In a pandemic scenario, a pandemic disease is a sickness that spreads across a large region, for instance, an entire country or the world. The origins of pandemics include animal and human contact with deadly agents such as bacteria or viruses. If a pandemic disease reaches an isolated island or remote area, it may take longer for humans to develop immunity against it.

In some cases, quarantine is not possible due to many people being infected at the same time. Terrorists have even engineered pandemic diseases to create biological weapons through genetic engineering. A global epidemic occurs when infections from all over the Earth are spread throughout the entire world in one season, rather than being confined to limited outbreaks within countries continents.

Electromagnetic Pulse

An electromagnetic pulse (EMP) is a short burst of electromagnetic energy. An EMP can be generated by naturally occurring events, such as lightning strikes and solar flares, and man-made events, such as nuclear explosions. Nuclear explosions produce gamma rays, which in turn make a pulse of electrical and magnetic energy. EMP effects were seen during atmospheric nuclear testing in the 20th century and by solar storms in 2012.

The burst of electromagnetic energy associated with an EMP disrupts or damages electronic equipment and infrastructure that rely on electrical power to operate. Although most people equate EMPs with lightning or solar events and think these can only cause minor problems, there is some concern about how much damage could result from an EMP caused by an artificial device such as a high altitude nuclear explosion (HANE).

HANE’s are sometimes called “Electromagnetic Pulse Bombs,” “Super-EMP Bombs,” or “E-Bombs.” Without question, HANE’s represent the most dangerous type of EMP, with the potential of being 1,000 times more powerful than a solar flare.

The effect of EMP on modern devices is what’s causing so much concern today. The average person has dozens of electronic gadgets connected to power cords and the Internet in their home or office. These include computers, televisions, microwaves, refrigerators, sewing machines, flashlights…even wind-up clocks!

All these devices are vulnerable to EMP effects because they all have computer parts, making them susceptible to damage from an “electromagnetic pulse bomb.” If you are caught out in the open during a high-altitude nuclear explosion (HANE), nothing will protect you from the direct blast energy of the blast itself.

Conclusion

Whether it’s nuclear war, a zombie apocalypse, or an electromagnetic pulse, there are many different ways the world could end. The best strategy for survival is to prepare now and know what you would do in each circumstance that may cause your demise.
