Global Change: a Public Health Researcher's Ethical Responsibility.

PURPOSE: Loss of biodiversity and globalized environmental degradation result in planetary-scale changes which impact human societies. RECENT FINDINGS: This paper highlights the urgency for public health researchers to integrate a global change perspective into their daily work. The public health community needs to answer several questions, e.g., how to weight the health of present and future generations; how to balance between the possible immediate adverse impacts of mitigating climate change vs. long-term adverse impacts of global change, how to limit the environmental impacts of public health intervention; and how to allocate resources. Public health practitioners are faced with a moral responsibility to address these challenges. Key elements to ensure long-lasting, innovative global change and health solutions include (i) empowering the population, (ii) tailoring the framing of global change and health impacts for different stakeholders, (iii) adopting less conservative approaches on reporting future scenarios, (iv) increasing accountability about the health impacts of mitigation and adaptation strategies, and (v) recognizing the limits of science.
