Cancer. that would be the most proper answer
I would say that <u>a deadly water-borne microorganism in a city's water source</u> would most quickly devastate a human population, merely because a huge number of people uses this water for some kind of a purpose.
The answer is: "social epidemiology" .

Hi !
The distinction between an accident and a risky behavior
An accident may be caused by something , someone else than you. You're not responsible for what happened. A car may have hurt you, you may have fallen and break your legs.....and you may be hurt by someone who has risky behaviours.
People having risky behaviours are aware of what they're doing. If something happen to them they are fully responsible.
Hope I helped !
