For me, the biggest problem right now is climate change. Due to development that does not pay attention to the environment, causing CO2 to increase. Eventually there is global warming. Global warming has a devastating effect on Earth.The consequences are:
-the temperatures on earth are rising
-the glacier at the poles melt
-water surface rises
-many animals lose their habitats and are threatened with extinction
-after will threaten human life

Well I am most afraid of North Korea. Look at that country by now. The north Korea is a great country possessing great army and weaponry. And take note. They also possessed nuclear weapons. And we do not know nuclear weapons could destroy this world in a second.
The scariest world problem is the climate change. Our climate has been extreme for the past years and even more extremer this coming years. We cannot even predict when would that calamity will hit the earth I do pray that i would not happen.
Climate change will be the worst.
The biggest problem for the whole world - Politicians do not want to negotiate among themselves. This problem and other problems and war, and famine, and even global warming.
The world's most frightening problem is the existence of corruptors who are not quickly destroyed, because the problem can eat enough people's money. 
What scares me is earthquake, storm and other natural calamities. I dont want to experience earthquake.
Nuclear war threats is the scariest world problem that we have right now
The climate change, as it's coming not from people, we can't even influence it
The most scariest world problem out there is the possibility of a war between 2 country which can effect the entirety of the world in general. The war might bring down major cities and country which can really devastate the economy and the life of the people in it. I hope we don't experience one.
Climate change is happening, global warming is already in the door, the long never ending winter, too hot summer in europe, too many raining in the not tropical country, the earth is getting old.
too many human nature will lead to destruction. human are greed and crazy to conquer. human nature is the true scariest world problem.
Climate change, it's kinda scary to think about it but it's real and happening.
Artificial Intelligence
I think future wars will be the option we may have to fear.
Any war is a lot of death and destruction, but after the war always there is a sharp upturn of the economy. The worst thing is irreversible consequences for the earth. For example global warming. And the war is not scary. The world has survived many wars and will survive many more.
Scarcity would the worlds biggest problem and that applies everything we need as a necessity like food, water, money and of course bitcoin. If there are less supply it'd be a problem for everyone I'm sure. If people have shortage of those basic needs then there would be chaos because everyone wold be striving to have those needs then comes war.
I think war and human conflict are the top! We are violent creatures and have a history of violence beyond anything else in our history. With that said, I think it will only help bitcoin. I think we will see a day (not for a while) where gov't currency fall apart - I mean there is simply too much debt in world gov'ts for them not to eventually collapse imo. With that collapse bitcoin will boom! Big time imo. Many moons away though
I absolutely agree with you. Among all the problems in the world, war is the scariest problem of them all. Come to think of it. Countries have been continuously fighting over territories. They do not think of what would be its effect to the people not just in their country but in the world. Why won't they just be contented on what they have? If the reason is resources, why won't they utilize the resources that they have and let the other use what's really theirs? Sometimes, the reason why wars are being experienced is because of greediness in power, resources, and the people.

A direct hit by an asteroid would make all the other problems go away very quickly. You can't say that about the other problems on the list, so an asteroid would scare me the most.
