Answer:
Because of the social and moral impact it expresses.
Explanation:
"A Harvest of Death" is considered the most famous and most important photograph of the American Civil War, due to the social and moral impact it transmits, making it a worldwide reference on the results of a war.
Photography shows that there is no beauty, civility and splendor in war, but death, rottenness, abandonment, lack of beauty and theft regardless of who is winning or losing. In this photograph, we can see Union and Confederation soldiers killed and thrown in a field. The heat of the sun caused their bodies to swell to the point of tearing their clothes, which sets a horrible scene. In addition, the soldiers are without their shoes and with their pockets turned outwards, showing that the citizens, deprived of resources, have removed, from the bodies of the dead, everything that could have any kind of value, so that they could meet their needs.
