The Love Birds

Introduce to you the mother and father of the babies. At first, I was puzzled why there was two birds with food in their beads take turns flying in and out of the nest instead of the mother bird only. Finally, I realised that the father bird also done his part in bringing food to the babies. This reflects to us that love exist in this world, we should preserve such love. I can't imagine why we human some time chose not to live in peace but go for war, commit crime and participate in terrorism. Your opions on this are most welcome.
