The researcher draws nine scenarios that are already hidden.
Destroying humanity from chemical weapons or lava to weapons of mass destruction may sound like a Hollywood movie scenario. The new report shows that there really is actually a possibility.
The global Cheltenham organization, which investigated the greatest risk that humanity could disappear, released the analysis that created Newsweek's most potent scenario.
According to Martin Rees, a British astronomer and co-founder of the Cambridge Existential Risks Center, people are afraid of the possibility of a fall, such as an airplane crash, and are at risk of crossing the "red line" in terms of rapidly evolving new technologies and environments.
"The possibilities may seem slim, but in our interconnected world, the consequences of this type of threat can spread terraced globally," Rhys said. Here are the scenarios in which we are most likely to prepare our fate in reverse order:
Nuclear war
Experts warn that the probability of a nuclear war is much higher than it was ten years ago. The Hiroshima bombing killed 150,000 people and the world has experienced another war so far.
An influential weapon has the power to destroy 80 to 90% of life forms at a radius of 1 to 4 km, including humans. There are about 7,000 nuclear warheads, and countries like the United States and Russia have the biggest weapons. Britain, France, China, India, Pakistan, North Korea and Israel are either nuclear weapons states or nuclear states.
Nuclear warfare can not only eradicate all cities and countries on the planet, but can also lead to a small era of radioactive contamination.
Biology and
Chemical warfare
Compared to other traditional means of attack, biological and chemical weapons are relatively inexpensive. At the same time, technological advances in genetic engineering and synthetic biology make it more than ever possible to use microorganisms for dangerous purposes.
If these small things are dropped or deliberately removed from misplaced laboratories, it could cause an infectious disease at an unprecedented rate, the report said.
fatal
weather change
In 2015, over 200 countries signed the Paris Climate Convention (President Donald Trump left the US last year), claiming that global warming will be limited to more than two degrees above the pre-industrial average. However, according to the authors of this article, the odds of going up to 3 degrees or higher already are 30%.
In this scenario, New York, Mumbai, Shanghai and other coastal cities will remain in the water, and a billion people living on the coast or low altitude will have to find new homes as climate refugees. Experts have clarified the possibility of eradicating human civilization without controlling the level of destruction.
Ecological
Collapse
The report stressed that a balanced ecosystem is necessary to survive on the current socio-economic level. Ecosystems are relatively resistant to human activity, but they can no longer tolerate it. Air pollution, aliens, the emergence of atypical species, and the destruction of natural habitats.
When an ecosystem loses its ability to recover, there is a lack of fresh water, soil degradation, and biodiversity seriously affected. This will lead to serious deterioration in people's daily lives. For example, Chad Lake, a victim of transient exploitation, climate change and drought, has fallen by 90 percent since 1960, which has already had a negative impact on the lives of 40 million people.
epidemic
The rate of disasters such as cholera and malaria has decreased significantly over the past century due to medical advances such as the implementation of large-scale immunization programs.
But the threat of a new epidemic and a new disease that we can not prevent is likely to occur in the near future. It is not likely to be infected with high-density urban areas and microbes in the water. Resistance to antimicrobials is also a major concern because it removes very important weapons in the fight against microorganisms and supermicro.
Asteroid collision
People's accidental attitude to their planet is not the only danger they face. The asteroid probably has extinct dinosaurs, and there is no reason to think that none of the large rocks that are circling the earth can attack again. According to existing data, a potentially catastrophic collision occurs every 120,000 years.
Experts are afraid that all of this will lead to pollution of the atmosphere that the sun has hidden for months. This will destroy crops and ecosystems and cause hundreds of millions of people to die.
NASA warns that 90% of Earth objects larger than 1 km are found and do not pose a direct threat, but only 30% of people at 140 m to 1 km are identified. However, the authors wrote that the blows from them could have significant regional consequences and indirectly lead to confusion in the social and economic systems.
explosion
Super volume
And explosion of expansion is defined as explosion of material over 400 cubic meters. Data on such eschatological events are limited and, in principle, volcanic eruptions are difficult to predict. Nonetheless, volcanologists believe that an explosion of high capacity occurs every 17,000 years, and certainly one of them came to New Zealand 26,500 years ago.
The eruption of super-sulfur from Yellowstone in the United States will destroy hundreds of thousands of horizons and animals and destroy agricultural infrastructure. Pollution by sulphate and dust will block the sunlight for a while, which will also reduce the temperature and this will also be a big threat to all life.
clear
Geotechnical
This approach is a double-edged sword. Spraying particles such as aerosols into the air and returning direct sunlight and heat to space can slow down the rise in harmful temperatures. But if all these things go wrong, life on Earth can be painful and disappearing.
The authors of this report warn that these activities can destabilize the regional and global climate as well as various elements of the global ecosystem. In addition, the abrupt termination of solar geoengineering will result in rapid and severe global warming, which will have no time and opportunity to adapt to natural and social systems.
A.I
The authors of this study are most concerned about the possibility that robots not only overtake human intelligence but also focus their companies on developing devices rather than ethics. Despite the efforts of these machines to have some kind of morality, minor mistakes can make people helpless slaves with a skill of a certain level of intelligence.
The most dangerous of all scenarios is not only the conversion of artificial intelligence into weapons, but also the destruction and sowing of deaths using smart machines programmed for good purposes.
