Meet Anne and Paul Ehrlich

---

The Ehrlichs have worked together since the 1950s, beginning their scientific collaboration through research on butterflies as a test system for answering key questions of biological classification, ecology, and evolution. Anne Ehrlich is a prominent American biologist and ecologist known for her significant contributions to the study of population biology, environmental science, and conservation biology. She is widely recognized as one of the most influential voices in the field of sustainability and conservation.  By 1993, the Ehrlichs’ perspective had become the consensus view of scientists as represented by the “World Scientists’ Warning to Humanity” and the statement issued by the Population Summit of the world’s scientific academies in New Delhi.

Ehrlich co-authored the book "The Population Bomb" with her husband Paul Ehrlich, which warned of the dangers of overpopulation and its impact on the environment. The book was a seminal work in the field of environmental science and helped to shape the public debate on issues related to population growth and sustainability.  

Paul Ehrlich’s book, “The Population Bomb,” co-authored by Anne Ehrlich, has been called a wake-up call for an entire generation. It warned of the dangers of overpopulation and its impact on the environment. The book was a seminal work in the field of environmental science and helped to shape the public debate on issues related to population growth and sustainability.  

Anne Ehrlich has conducted extensive research on butterfly populations, studying the impact of habitat loss, climate change, and other environmental factors on these species. Her research has helped to improve our understanding of the complex relationships between species and their environment.  

Paul Ehrlich’s contributions on the population ecology of butterflies led to development of the powerful concept of co-evolution (with Peter Raven, Ph.D.), an important understanding of the dynamics of animal populations. 

Anne Ehrlich is a strong advocate for environmental conservation, and she has worked tirelessly to raise awareness about the impacts of human activities on the natural world. Her advocacy has helped to shape public policy and has inspired countless individuals to take action to protect the planet.  

Ehrlich's contributions to the field of conservation biology have had a significant impact on our understanding of the natural world and on efforts to promote sustainability and protect biodiversity. Her work continues to inspire new generations of scientists and environmental advocates.
