Steve Dunn is a retired journalist who has self-published two books, about former State Senator Pat Deluhery’s political career and the history of professional baseball in Des Moines.

Retired anesthesiologist Dr. Dick Wheeler of Des Moines put people to sleep for a living. Now he wants to wake people up to what he believes is the No. 1 threat to humanity: overpopulation. At 103 years old, Wheeler is more concerned about the future of his four children, eleven grandchildren, and fifteen great-grandchildren than his own.

He has been concerned about overpopulation for a couple of decades. “I read one article about it, which had a bunch of statistics that really alarmed me,” he explained. “Someone had asked a group of experts of various persuasions how many people could Earth support. After due consideration and research, they decided all the way from 11 billion to 17 billion.”
