“…Using systems thinking (Figure 3), we show the interconnections among the seven drivers of zoonotic diseases, climate change, and biodiversity along with factors that influence the transmission of COVID-19 and other zoonotic diseases, such as urbanization (Connolly et al, 2020), population density (Simpson et al, 2020), and international trade, which has been linked to invasive species introductions (Gallardo et al, 2015). Causal loop diagrams and systems thinking are useful for representing interconnections, causes, and effects in complex systems (Lezak & Thibodeau, 2016;Palmberg et al, 2017) and have been used to represent the connections in the interacting domains of the environment, agriculture, climate change, and international trade (Ortiz et al, 2021). This diagram will undoubtedly simplify the complex and nuanced connections between these domains.…”
