Sorry, I'm incompetent. Copy and paste from my mobile phone to ask:

From a photo: hungry children and vultures

A child in Sudan is trying to climb to the UN Food Relief Office. Along the way, he was stared at by a greedy vulture, apparently starving to death. The vulture was waiting for that moment, expecting a good meal. Photographer Kevin Carte won the highest honor in American news reporting for taking this shocking photo, but committed suicide three months after taking the photo.

Because of this photo, kevin carter was criticized by people: Why didn't the reporter leave the camera and give the dying child a pot of water and a loaf of bread? Why not save the child from the sickle of death and the beak and claws of vultures? Isn't a child's life worth less than a news photo or a news award? The reporter explained to public opinion that at that time, African countries were starving and there were deaths everywhere, and external assistance was just a drop in the bucket. No one can do anything about the death of the victim. When he left the local disaster area with a heavy heart, when the plane carrying out the task had started before he was about to board the plane, he saw this heartbreaking human tragedy, immediately turned around and photographed it, and then had to leave quickly. But the public opinion did not stop because of his explanation. Finally, the reporter thanked the world with his own life. 1On July 27th, 994, kevin carter was found dead in his small train, apparently committing suicide, at the age of 33.
