I have a great one for you! Write about women in the military and use some key points:
1) If men (tribal days) went to war and only two men survived, but all 20 women were safe in the cave, the tribe could reproduce and continue on as a powerful tribe. If 2 women returned to 20 men, only two children a year could be had and only two of the men might survive the fight for the remaining women. Now, there are 6 billion people and we worry about over-population.
2) The military had less checks in the former days and could not prevent men from raping citizens of conquered lands, let alone women if they were in the military. Now, we have security measures even if it is not perfect
3) Men are generally stronger than women, but a women can press a 'launch missile button' as well as a man can. No more having to have large mussels to kill with swords
4) Men still have a hold back on killing women, but it is impossible to tell who is in a plane: man or woman.
Hope this helps
