Objectives: We aimed to critically evaluate the extant and probable links between plant function and human health, drawing on the pertinent literature. Discussion: Here we provide a number of critical examples that range over various health concerns related to plant biology and climate change, including aerobiology, contact dermatitis, pharmacology, toxicology, and pesticide use. Conclusions: There are a number of clear links among climate change, plant biology, and public health that remain underappreciated by both plant scientists and health care providers. We demonstrate the importance of such links in our understanding of climate change impacts and provide a list of key questions that will help to integrate plant biology into the current paradigm regarding climate change and human health. Key words: aerobiology, contact dermatitis, food security, pharmacology, toxicology.
