Everyone talks about climate change, but no one discusses overpopulation. 2000 years ago there were 300 million people living on earth. Today there are 6.8 billion, and our population numbers continue to grow - with disastrous consequences. As the affluence of industrialized countries is based on inexpensive fossil fuels, and slowly but steadily these fuels are running short, billions of people live in poverty - and their numbers are increasing daily.Dudo Erny not only elaborates on the consequences of overpopulation, but also its causes. He breaks taboo after taboo and more than once faces the question of why so little has been written about the overpopulation crisis until now.
