Let's just say all men disappear from the face of the Earth tomorrow. Do you think women would be able to maintain civilization? I personally don't think they would be able to do it. Because women would be unwilling to do the tough and dangerous jobs men do to keep civilization running. Jobs such as mining, repairing bridges, building cars, planes, trains, ships, constructing tall buildings, ocean fishing, building rockets and so on. Do you really think women are capable/willing to do these kind of jobs?
