What do environmental contaminants and climate change have in common with the virus SARS‐CoV‐2 and the disease COVID‐19? We argue that one common element is the wealth of basic and applied scientific research that provides the knowledge and tools essential in developing effective programs for addressing threats to humans and social‐ecological systems. Research on various chemicals, including dichlorodiphenyltrichloroethane and per‐ and polyfluoroalkyl substances, resulted in regulatory action to protect environmental and human health. Moreover, decades of research on coronaviruses, mRNA, and recently SARS‐CoV‐2 enabled the rapid development of vaccines to fight the COVID‐19 pandemic. In the present study, we explore the common elements of basic and applied scientific research breakthroughs that link chemicals, climate change, and SARS‐CoV‐2/COVID‐19 and describe how scientific information was applied for protecting human health and, more broadly, socio‐ecological systems. We also offer a cautionary note on the misuse and mistrust of science that is not new in human history, but unfortunately is surging in modern times. Our goal was to illustrate the critical role of scientific research to society, and we argue that research must be intentionally fostered, better funded, and applied appropriately. To that end, we offer evidence that supports the importance of investing in scientific research and, where needed, ways to counter the spread of misinformation and disinformation that undermines legitimate discourse.
