10 ways the world is most likely to end
The Global Challenges Foundation which works to address the threat of global issues to humanity publishes each annually-released report on global catastrophe dangers. The group released group published the report for 2018 in the month of September and the list is terrifying The report includes: Chemical warfare, supervolcanic eruptions collisions between asteroids, and growing consequences of climate change could to trigger everything from civilisational collapse to the extinction of humans. What would be a better option to end the earth?
Certain of these risks sound as if they come from science fiction, however, they were the use of weapons of mass destruction as well as changes in the weather 100 years ago. In the words of Allan Dafoe and Anders Sandberg of the Future of Humanity Institute write their report, our brains don’t excel in thinking about the possibility of catastrophic risk, because they “completely ignore or are massively overweight” items with very unlikely to happen.

The positive news:
The positive news for us is that scientists believe that the globe can be inhabited for at most several hundred million years. The bad thing is there’s a lot to change the way things are. The risks mentioned in the report creating mass casualties are tiny however this doesn’t mean they rent worth paying attention to and especially in the event that the worst-case scenario could lead to the end of humankind.
Here’s what’s likely to keep you awake at night, and what is likely, will cause humans to become like dinosaurs.
1) War with nuclear
A nuclear explosion by one of today’s most potent weapons could cause a blast with a fatality rate of between 80 and 95 percent within the blast zone, which extends up to a radius of four kilometers, though “severe destruction” could extend six times that far.
However, it’s not just the deaths that we have to be concerned about. It’s an entire nuclear winter. It’s when the clouds of smoke and dust created by the explosions engulf the planet and block the sun, causing the temperature to fall, perhaps for several years If the detonation of 4,000 nukes weapons happened.
The biggest concern here is the nuke arsenal. Although the number of nukes has decreased over the past few decades there is a huge gap between the United States and Russia have the largest arsenal of just less than 7000 and 7,000warheads each which is the biggest collection around the globe. It is believed that the UK, France, China, India, Pakistan, North Korea, and Israel all possess nuclear weapons.
A plethora of nuclear weapons are in the process of being released in a matter of minutes and this is a disturbing fact given that the greatest danger of nuclear war could be the result of a mistake or miscommunication. There have been a few instances since the 60s Russian officials (and later, on the day of 95 President) narrowly decided not to unleash an attack with a bomb in reaction to what they would later discover were false warnings.
2) Chemical and biological war
In contrast to nuclear weapons that require sophisticated engineering, biological and chemical warfare can be made at a very low cost and using relatively accessible materials.
Over the past several years over the past few years, in the past few years, Syrian government has been using chemical weapons during the civil war that has devastated the country. The chemical attacks using chlorine and sarin have shocked the world and highlighted the harm chemical weapons can cause. Chemicals that are toxic to humans can do immense harm to a particular area — for example, when the poisons were released into the air or the drinking water system.
Bioweapons pose a more risk of catastrophic destruction. The advancements in synthetic biology have made plausible the possibility that malicious actors could create dangerous pathogens that could be used to weaponize. If there were an epidemic that is rapidly spreading, the world would be extremely at risk.
3.) Changes in climate that are catastrophic
A United Nations panel of scientists released an article last week stating the world is only given 12 years to reduce the global temperature from rising to moderate levels.
The projections of the impact of climate change differ based on the extent to which the Earth gets warmer (usually modeled using an increase of one to 3 degrees Celsius). All of these scenarios appear very promising.
At the very least, we’re seeing more frequent and intense tropical storms. Midrange predictions suggest the destruction of the vast majority of the planet’s world agricultural water sources and land and major coastal cities such as New York and Mumbai ending in the sea. At the very least, humanity could end.
Catastrophic changes in climate are not something we pay sufficient focus on Leena Srivastava, acting director general of the Energy and Resources Institute, states that we’ve invested enough resources and time into the safety of airplanes that we only have 27 planes involved in crashes every year. However “if the possibility of dying in a plane accident were more likely than a 3degC global temperature rise and it would mean that the number of passengers killed in planes each year would be around 15 million in the United States.”
4.) The ecological collapse
Ecosystems are the fragile community of living creatures, such as animals and humans, that interact
with their non-living surroundings such as the air or water. According to the study, we could be nearing that threshold.
Lake Chad in West Africa Lake Chad in West Africa is an illustration of the ecological decline. The drought of the past 60 years, the overuse of water, and the effects on climate have diminished this lake to 90. The massive reduction has negatively affected the lives of over 40 million people from Chad, Nigeria, Niger, and Cameroon who depend on it.
Researchers believe that this point in the past is the beginning of an era of geological change known as”the Anthropocene. In the present era, humans are the main change agents, swiftly destroying what makes the earth habitable, increasing the concentration of greenhouse gases, and harming the health of marine ecosystems. the well-being of marine ecosystems.
Twice in recent history, the world has been struck by plagues. the globe with the potential to kill around 15 percent of people in only a few years. They happened in the 5th and 14th century and 14th centuries, respectively -but there’s a high possibility that an infectious disease that is new could trigger another outbreak, especially in the current world population that is mobile and urban.
Fortunately, deadly diseases that have the ability to spread across the globe are extremely rare. However, they occur — in the past century, Spanish flu claimed the lives of over 50 million persons. The outbreaks of SARS as well as Ebola in recent years raise alarm alarms.
Our most effective defense against illness is losing effectiveness since certain varieties of bacteria develop resistance to them. Antibiotic-resistant bacteria account for the deaths of 700,000 annually. If we don’t come up with new methods to fight the resistance to antibiotics, the amount could reach 10 million by 2050.
6.) Impact of steroid
Asteroids are rocks that revolve around the sun and occasionally collide with Earth. Asteroid sufficient in size to cause an all-encompassing catastrophe strikes Earth each year for 120,000 years according to scientists. It’s probably what killed dinosaurs. And if an asteroid that was even a tenth of as large as the one that led to their extinction came upon Earth in the present, the consequences will be devastating.ASA declared in 2011 that it had identified over 90 percent of space objects larger than 1 kilometer in size and found it was found that none of them were likely to impact Earth. However, there’s a lot we do not know about smaller objects that, though unlikely to cause a major catastrophe, however, could cause a large enough impact on a local scale to cause disruption to economic and social systems.
7) Supervolcanic eruption
Certain experts believe this was the cause of the largest mass extinction of animal and plant species in the history of mankind, pushing the species close to the point of extinction. What would be a better option to end the earth?
It’s difficult to tell as we don’t have a lot to compare it with however data suggests that an eruption of supervolcanic origin occurs approximately once every 17,000 years. If this is true that’s the case, then we’re the long overdue most recent one we’ve heard of was in the year 26,500 located in New Zealand.
There is no way to anticipate eruptions for more than several weeks or months ahead as well as we don’t have any method to decrease the possibility of eruptions at moment, however, scientists are monitoring a variety of areas at risk, such as Yellowstone and Yellowstone in the US.
8) Solar geoengineering
There’s a drastic option to stop or reverse the rise in global temperatures however, it’s a significant risk.
Solar geoengineering will reflect heat and light out of Earth and back to space through the injection of aerosols into the stratosphere which is the 2nd layer in the Earth’s atmosphere. It currently is only a computer simulation however, the first test is currently being planned through Harvard researchers.
Solar geoengineering is among two technologies emerging that can alter the atmosphere and decrease the risk of climate change. Another is the direct removal of CO2 from our atmosphere. This isn’t available yet on a sufficient scale.
If geoengineering in the solar system were to be implemented in the future, it could affect the entire atmosphere and would be humanity’s biggest-ever global project. Although it’s the only method that has been identified to slow the rise of temperatures. Any manipulation on this scale without knowing the consequences could be disastrous for humanity.
9) Artificial intelligence
Researchers have estimated an average of there is 50% possibility that AI being able to perform all tasks or even better than humans by 2050. There is at most a 5-percent possibility of surpassing human intelligence just a few years later.
It’s a popular belief that the biggest threat to AI could be that AI can become evil according to the report: “If you ask an intelligent, well-behaved car to drive you towards the airport as quickly as feasible, it could be able to get you there, surrounded by helicopters, and be splattered with vomit, performing not the way you would like but exactly the thing you wanted.”
10) Unknown dangers
It wasn’t so long back that nuclear war and climate change were almost unheard of. These days, we’ve seen the devastating consequences and we’re worried that they’ll become much more severe.
