Climate change forces people to cross borders.

One extra reason for concern that was not examined in the study (since it is much more difficult to predict) is the appearance of new pathogens that spread from animals to humans. In this aspect covid is the rule, not the exception and this single disease have had a huge impact that would have been impossible to predict in 2019, climate change can increase the risk of the next pandemic to begin and cause similar disruptions.
