The two-day conference on the "One Health" framework concluded by identifying critical issues and systemic barriers. These included major public health concerns regarding harmful environmental exposure affecting vulnerable groups, even at low levels. Furthermore, a critical lack of communication and collaboration between diverse environmental and health organizations is leading to severe ecological consequences in shared ecosystems. Moving forward, the conference proposed seeking funding for practical and effective ecological actions and establishing governance measures for better control and binding collaboration among organizations.
