Hoak eat baby bird

This a video about a hoak eats a baby bird...It was shot by my friend and I was beside her... During the procedure, the mommy and daddy attack the hoak all the time...BUT, nothing change... It happened on our campus... Some people may blame us that why we didn't stop this cruel behavior... However, what can we do? Throw a bottle to the hoak? Is it the same as the hoak eats the baby dird... This scene lets me remeber a famous photo---“Pulitzer Prize” winning photo taken in 1994 during the Sudan Famine. That picture depicts stricken child crawling towards an United Nations food camp, located a kilometer away. That vulture is waiting for the child to die so that it can eat him. This picture shocked the whole world. No one knows what happened to the child, including the photographer Kevin Carter who left the place as soon as the photograph was taken. Three months later the photographer committed suicide due to depression. This is the rule of the nature...Nobody knows whether the baby of the hoak is still alive and maybe the baby hoak has been eaten by another bigger bird. At some point, we are the most cruel in the nature because we eat amost all the plants and animals... We grab the animal in order to let them in our zoo, let them perform and let them to follow us... The video shocks me very much...The family ties and the cruel rule of the nature...
