In the rest of the book Ehrlich discusses things which readers can do to help. This is focused primarily on changing public opinion to create pressure on politicians to enact the policies he suggests, which he believed were not politically possible in 1968. At the end of the book he discusses the possibility that his forecasts may be wrong, which he felt he must acknowledge as a scientist. However, he believes that regardless of coming catastrophes, his prescriptions would only benefit humanity, and would be the right course of action in any case.
