Carnegie Museum of Natural History’s active research team is studying the natural world and how the billions of humans on Earth are impacting it. Population Impact is an exhibition that highlights their work and examines how the choices humans make affect our environment.

Population Impact focuses on real-world issues such as changes in the human population through history, urbanization, and the effect of human populations on plants and animals. Watch as the population map changes across the timeline of human history, explore the ways in which population growth affects four global cities, and discover how changes in medicine and science alter populations.

The exhibition focuses on the research projects conducted by Carnegie scientists, like documenting animals and plants in the endangered mountain forests of Hispaniola (Dominican Republic and Haiti) and addressing the highly debated white-tailed deer population of western Pennsylvania.

Population Impact also examines the work done at the museum’s environmental research center Powdermill Nature Reserve, where one of the country’s longest running bird-banding programs tracks bird migration and populations.
