A University of Maryland study published in Frontiers in Environmental Health finds that wildfire smoke is now systematically offsetting the prenatal air quality gains achieved since the 1970 Clean Air Act. Despite an 80% reduction in human-source air pollutants, fossil fuel-driven climate change has intensified wildfires, making their smoke a greater threat to prenatal health—particularly for low-income, rural, and Indigenous communities.
Background
The Clean Air Act of 1970 has successfully reduced emissions from vehicles and industrial sources by nearly 80%, but climate change driven by fossil fuel combustion is increasing wildfire frequency and intensity worldwide.
