In this special issue, we document the broad and emerging impacts of U.S. government funding cuts on a wide range of research and projects in the U.S. and abroad, the scientists who conduct that work, and the people who benefit from it. We highlight public health in action—at the Comstock Center, on construction sites, and in labs both mobile and brick-and-mortar. And we share stories with lessons that can help us navigate the current moment—from Argentina, from the School’s history, and from the real-world experiences of our faculty, students, and alumni.

In this special issue devoted to planetary health, our writers explore many of the ways humans have transformed Earth's natural systems to the detriment of human health: the rising infectious disease risks associated with disrupted ecosystems, the nutrition deficits caused by increased CO2 levels, the health and environmental costs of industrial food animal production, the physical and mental health tolls of higher temperatures. They also highlight research aimed at repairing the harm: climate-smart transportation, preserving glacial ice, reducing food waste, and constructing sustainable cities are just a few approaches. The Earth crisis is urgent, and this issue shows that public health and planetary health have tools to meet the moment.
