This document discusses environmental health issues and solutions across three eras: 1) The U.S. Civil War era 1860-1865 2) The early-mid 20th century period of increased legislation like the Clean Air and Water Acts 3) The current era where the environment is negatively impacting human health through events like wildfires and hurricanes. It calls for environmental health professionals to provide policy solutions, clearly define their roles, and communicate a vision focused on public health issues. Standardized approaches are suggested for issues like wildfire clean-up and respiratory protection. The future of the field is discussed as requiring agility, experimentation, and viewing science in its social context.
