I might try to write this but might as well put it here.

This was inspiried by Local 58 analogue horror series ("Contingency" episode in perticular)
It's about the world when humanity goes extinct. Not in some cataclysm but on their own will, without violence and peacefully. I imagine idea of anti-humanism spreading quickly through population, and how suicides and murder is normilized (and later gloryfied) in media. Politicians push mandatory sterilazation for all teens, but it's not like anyone is opposed to it. When last fertile people are dead or can't reproduce anymore, the president (wich I imagine to be a woman) appears on all tvs and thanks everyone for taking part in making a "world piece" and calls upon act - mass suicide. To show example, she executes herself live. This might involve just random suicides, organised disposion, or, in case perticularly big cities, gathering everyone together and just nuking the whole place. Is this too dark?
