Well, for economic effect: the economy boomed (in america). War efforts make the economy boom, with guns, ammo, rations, etc. Women were given jobs in factories. For environmental: bombs, trenches, and guns ravished the land. Buildings and cities were bombed, people were killed, fields were covered in mud, dead bodies, and trenches. Rats and lice were rampant. farms were destroyed.
