What type of crisis would you consider to be best for humanity to overcome in order to "change" (open to your own interpretation)?
It isn't much of a crisis for the whole of humanity unless there's a possibility of our extinction.
Obviously the crisis type the highest chance of us surviving would be "Ourselves" and the crisis type with the highest chance of us getting wiped out would be "Extra-terrestrial threat" (because I highly doubt a space age civilization capable of travelling all the way over here would have a hard time wiping the floor with us, if they so wished).
Take note that ,for example, "Extra-terrestrial threat - alien invasion" indicates the type of crisis (i.e. a crisis involving intelligent extra-terrestrial beings) and then after the dash is an example of the said type of crisis (i.e. an alien invasion).
Also, I know that technically solar flairs and asteroids are of extra-terrestrial origin, so there's no need to point that out.
Here is a explanation of the types:
Ourselves - we are the cause of our own crisis point.
Gradual - the crisis happens over a period of time.
Sudden - the crisis happens suddenly without warning.
Imminent and unavoidable - the crisis' occurrence is imminent (i.e. it hasn't happened yet) and unavoidable (in other words the crisis point is the anticipation of the crisis).
Extra-terrestrial threat - the crisis is a result of intelligent extra terrestrial beings (as apposed to unintelligent extra-terrestrial beings (need I provide examples?)).
None at all - we don't need a crisis to spur us to "change" (self explanatory).
None - humanity wouldn't come out any "better" anyway (self explanatory).
Other/specific - you don't like my options/ you hate my guts/ you want to suggest a more specific type of crisis/ you wanted to click something.
EDIT: just noticed I put "Immanent" instead of "Imminent" in the poll. please excuse that mistake. Also just noticed that there's a limit to the length of the question asked in the poll (that or I mis-typed it)?
