The author has retired and spends time protecting endangered animals in Africa. He has found that elephants and rhinos are being slaughtered industrially for their tusks and horns. Additionally, rich people like Donald Trump's son believe they can hunt these animals for fun. The author wrote a novel called "Rare Earth" to expose these practices, which upsets him to write about. He is trying to fund his conservation efforts through sales of the novel and asks the reader to purchase or share it to support stopping the killing of these animals.
