A science journalist has shown eight ways the world could go down, with deadly biotechnology, terminator robots, and nuclear war the biggest threat to life on Earth.
Bryan Walsh, 41, a former foreign correspondent and author of Brooklyn, also addressed climate change, super-volcanoes, asteroids, diseases and even aliens in his new book.
End Times: A Short Guide to the End of the World After Walsh had spent two years investigating the terrible possibilities of the world face Armageddon.
He has assessed both the severity of each disaster and the likelihood of its actual occurrence.
Mr. Walsh says, " I do not want people to feel us." It's doomed to failure and the world will go down tomorrow and all.
"I want them to see that in each of these risks things are done or that we can do something.
"We have to make it clear that these disasters do not happen because you can not hide in a hole for years to avoid this.
The most credible and unsettling threat to planet Earth is biotechnology, according to Walsh.
He fears that extremist scientists experimenting with diseases may develop a super-virus that could withstand vaccines and antivirals, with the intention of killing a large amount of the human race.
The use of genetic engineering in disease, he notes, can change people's lives For the better, but the catastrophe that could happen if done wrongly or in the wrong hands could bring the world to a standstill.
The most credible and unsettling threat to planet earth is, according to Walsh, biotechnology (file photo) eerie point t In recent years, ISIS and former Al-Qaeda have been trying to combat the smallpox disease that has existed since 1977.
The death of such a disease or the recent threat of Ebola in conjunction with the rate of infection of a common cold could cause chaos and create the "perfect bio-weapon".
Mr. Walsh says, "This is the one I consider the most worrying. It's the ability to use new technologies, such as gene processing, to create viruses that are worse, more contagious, and deadlier than anything else in nature.
In one example he uses the John Hopkins Center for Health Security in Washington DC found that 150 million people were killed by a biotechnology disease – 2 percent of the world's population.
The effects of this disease are also costly in the experiment as economies collapse and unemployment spikes.
The terror caused by the public's recognition that the deadly disease is not a freak act of nature, as is usually the case, but is caused by the "malice" of radicals or "an alienated scientist" the Pandemonium only reinforced.
And if produced, the variety could be repeatedly publicized, leaving physicians and scientists in a losing battle for the treatment of those affected.
"It is worrying because only a normal disease can kill many people," says Walsh. "But if you intentionally or accidentally make something in the lab that's even more powerful than anything in nature, that's really dangerous . "
Criminals may not be that far from accessing the deadly biological weapons.
Mr. Walsh warns that unlike in the past, only a small number of twisted virologists need to realize the dream of the terrorists.
And as he adds, there are about 1 million scientists with the ability to commit to such a task.
But there is hope.
Mr. Walsh is also in the linked world of gene sequencing, where researchers now have the ability to quickly diagnose diseases and prevent their undetected spread.
He says it may be an option to compete with the slower process of vaccination.
This might be the way, according to Walsh, to counteract an outbreak of super viruses – with an equally effective technical antidote that can suppress the error among those affected before killing millions.
Another product of Man's tremendous technological advances is the fear that the Terminator movie could now be realized ,
Breakthrough in Artificial Intelligence (AI)) has been blown up in the last decade when creators pursued a growing demand for robots to make life easier at home.
But could it threaten the world in the same way that the cyborg assassin of Arnold Schwarzenegger did in 1985?
The result of man's tremendous technological advances is the fear that the Terminator movie (pictured) could now be realized.
Walsh says, "If we can actually develop an AI that is truly intelligent, it can feel like a buzz. A being that is really disturbing.
He warns, "It could mean it could literally take over.
In a shocking demonstration of power transfer, he adds, "We're going to be junk.
The threat stems from the fact that computers are now "learning" and taking away the control people have.
Fortunately, Walsh says, machines are currently hidden from people in what they are allowed to learn
But their ability to store huge amounts of data and process them far faster than the human brain means they could become far superior intellectuals – "superintelligent," as Walsh puts it.
And our widespread presence According to the author, this planet could stand in the way of the robots' plans and lead to our extinction, just as humans have done with less intelligent animals such as the dodo and the western black rhino.
There is a flip side – the Creation of superintelligence could lead to superchances.
The potential to live forever through & # 39; consciousness in a virtual sky & nbsp; Make AI our ally and savior instead of killing him.
At this stage, however, Walsh says: "It's really hard to say [which way it will go] because it depends on what you're going to do with AI.
"We are essentially at the top of the food chain on this planet because we are the smartest species that was created."
Still, he adds, "But creating a smarter species than we could possibly be worrying."
Severity: 9/10  The nuclear war is possibly the largest talked about and foreseen the end of the world.
The huge stock of weapons after the Second World War as well as the increasing tensions between superpowers like the USA, Russia and China in recent years can lead to catastrophes.
The largest and most powerful thermal-nuclear bomb ever detonated was the RDS-220 hydrogen bomb, Kno wn as the "Zar Bomba."
The atomic weapon was transferred to the Soviet Union on October 30, 1961 Anniversary Tested.
Nuclear war is perhaps the most discussed and anticipated way the world will end (File photo)  But the devastating bomb had the explosive power of 3,800 Hiroshima bombs and sent a mushroom cloud of 130,000 feet or four and a half Mount Everest high.
It is estimated that up to 166,000 people were killed in the attack on Hiroshima. This means that a "Zar Bomba" has the potential to wipe out 630,800,000.
This is about two of the United States.
Mr. Walsh describes the nuclear threat as "the last curtain on humanity."
[Nuclear war] is still a big problem and has actually deteriorated in recent years, as you have seen. Together with the US under Trump and Russia under Vladimir Putin they both withdraw from the global arms control treaties ", says Walsh.
Commenting on the massive Nyonoksa explosion in Russia on August 8, he adds, "You know, a few weeks ago, we saw the accident related to one of its nuclear weapons programs in Russia.
"This is quite disturbing and you see a lot of aggression both there and in China."
In his book, Mr. Walsh deals with the history of the atomic bomb, and traces it back from its origins during the Second World War to the Cold War to its own experience of the nuclear threat.
He Notes US Scientists and Military Chiefs at the Time It was the largest and most powerful thermal-nuclear bomb ever detonated, the hydrogen bomb RDS-220, known as the "Tsar Bomba". (pictured) ” class=”blkBorder img-share” />
He believes that the short-term success of a more powerful nuclear arsenal for politicians overshadows any attempt to investigate the long-term threat.
He says, "I think we have to choose leaders smart enough to retreat from the brink of war, we must realize what we are doing towards the end of the Cold War, where leaders come together and make contracts
"We need people, the public, to get them moving in. Once there was a public opinion about it, but nowadays they are not so closely related anymore."  In a man's daily life, the prospect of nuclear war remains unlikely and unthinkable scenario, says Walsh.
It "still defies reality," he adds.
Despite the threats posed by the other seven in Factors being discussed in his book, nuclear power is the "most significant existential risk we are exposed to now, today."
He relates that there is no defense against them and that they have the potential to "deny ruin the entire planet and even destroy our species ".
A human being remarks, "It makes me angry to know that my son was born into a world where this fear is very real again."
Still, Mr. Walsh discusses the things people can do to survive a nuclear war.
Perhaps surprisingly, he says, "Ducking and covering is actually a good piece of advice."
However, this only applies to small nuclear weapons such as kilotonnes bomb.
In the case of a complete nuclear war, he cites the historian Alex Wellerstein the words: "One can not do much."
Supervolcanoes are the most dangerous natural threat to existence, according to Walsh.
Dangerous asteroids can be traced decades before they could affect the Earth, whereas humans know far less about the much more obvious threats to volcanoes at home.
And super eruptions could be planned at any time, said Mr Walsh Jonathan Rougier, a scientist from Bristol University , citing that an explosion could occur every 17,000 years.
Supervulkane (photo archive) are the most dangerous natural existential threat food, according to Mr. Walsh  The last one was more than 26,000 years ago, which made us overdue.
Mr. Walsh calls the Yellowstone Park in Wyoming a sobering example.
The world's most famous super volcano has had three super eruptions in the last 2.1 million years, and it is still very active, writes Mr. Walsh.
If it exploded, it would destroy life as Magna spurts out of its 28-mile-wide caldera, which was caused by the last explosion 640,000 years ago.
Mr. Walsh outlines how the Super Volcano could possibly end this world.
There would be violent earthquakes as magma rages on the earth's surface, followed by a "titanium eruption" when the giant toxic discharge breaks through.
Lava would devour 40 miles around the National Park and continue to spit ash and gas for days on end.
It is these gases that pose the greater threat to life on Earth as they rush 15 miles into the atmosphere, plunging much of the US into darkness and ripping people apart of tissues and eating their lungs.
