I would say government and rights of the public to decide whether we should war or not.
WWII affected women in a great way! During his time of war, the women at home helped build big planes and bullets and artillery shells being used by their boyfriends or husbands or brothers and fathers in Germany fighting. But also this gave the woman the time to stand up for women's rights and to fight for equality of pay and work. without the women's help in the factories back at home our army would have been in trouble overseas.
Flooding rivers helped contribute to the beginning of farming communities because of sediment deposits that would be spread beyond the banks of the river to the land near rivers. This sediment helped to create highly fertile land that could then be used for farming. The mineral rich sediment helped to develop early farming and allowed for the natural cycle of rivers to boost agricultural production.
