Harriet Ritvo explores the intersection of environmental history and environmental concerns, emphasizing how the discipline reflects the growing awareness of global environmental challenges. While environmental history often aligns with national boundaries due to evidence and legal frameworks, the environment itself transcends these borders, offering opportunities for broader, transnational approaches. Despite the challenges of distilling complex scholarship for public and political engagement, environmental history continues to flourish, driven by contemporary environmental issues. To advance further, the field must internationalize its priorities and draw from interdisciplinary sources like geography and evolutionary biology to enrich its global perspective.
