The Greatest Threats To Humanity!

It might seem like the end of the world is nigh at times because of catastrophic storms, the refugee crisis, and the genuine fear of nuclear war. But what are the biggest problems facing mankind, and is there anything we can do to avert them?

Every year, experts from the University of Cambridge's Center for Study of Existential Risk and the Global Challenges Foundation in Stockholm use scientific research to examine this issue.

Some threats might occur millions of years in the future, such as asteroid-like gamma-ray bursts from stellar explosions that would wipe out our ozone layer or perhaps cause the cosmos to implode or expand too much.

Closer to home, we have our Sun, which will eventually age into a red giant and swallow the entire planet, but that won't happen for another five billion years. Even more imminent is the possibility of an asteroid big enough to cause a global catastrophe, which is thought to happen every 120,000 years. Although none are currently predicted to strike Earth anytime soon, there is still a global effort to search the skies.

If it occurs, it may trigger a worldwide chilling catastrophe similar to the Ice Age. However, even smaller asteroids might have a major effect on human and natural ecosystems; one even closer possibility is the supervolcano that caused Mount Vesuvius' destruction in Pompeii.

Supervolcano

released around four square kilometers of magma, but these mega volcanoes are capable of releasing more than 500 square kilometers. The main concern from this, though, is the ash cloud that would block off sunlight, cooling the planet and severely impairing agriculture. Researchers estimated that eruptions happen every 30,000–50,000 years, with the latest reported eruption in New Zealand occurring around 25,000 years ago.

Scientists are keeping an eye on Yellowstone in the United States as a possible future location, but not all of our concerns come from natural overpopulation that might surpass Earth's ability to generate enough food and other resources. The risk of infectious pandemics is increased by overpopulation because of high densities and perhaps because of bioengineered illnesses.

On the other hand, data is already suggesting that fertility rates are dropping. Will this mean that there won't be as many people born as there are now?Changes in Climate

Will climate change outweigh this worry? Three degrees Celsius more would be extraordinarily?

In addition, longer and more destructive wildfire seasons, more powerful hurricanes, heat waves, food insecurity, and droughts can all have an impact on and amplify violent incidents in countries already experiencing problems with water and climate, which in turn can have an impact on declining economic conditions.

Furthermore, tensions surrounding North Korea and the nuclear weapons have elevated this confrontation to a new level.

Russia and the US have 7,000 known warheads, while the UK, France, China, India, and Pakistan have nuclear weapons. North Korea and Israel the Doomsday Clock that was produced by Atomic Scientists Bulletin

Since its establishment in 1947, nuclear war has received a lot of attention. The closest we've ever been to midnight or the end of the world was in 1991, when the clock was 17 minutes to midnight. As of now, in 2017, the clock is 2.5 minutes to midnight, which is the second-closest it has ever been.

A nuclear winter might result from even a little nuclear conflict.

It can eventually result in droughts lasting longer than ten years due to global cooling and ozone layer destruction.

However, the biggest threat facing researchers today is artificial intelligence. Experts estimate that if growth continues at the rate of the industrial and agricultural revolutions, autonomous machines will reach nearly human intelligence levels by 2075. Even if these machines don't turn evil or become malicious, what happens when AI designed to do good ends up being used destructively or when it is programmed to kill?
