The Covid-19 culprit is us, not pangolins (Opinion)
CNNEditor’s Note: Dr. Robert Breiman is an MD and a professor of Global Health and Infectious Diseases at Emory University. Scientists have found coronaviruses, genetically similar to the Covid19 virus, in pangolins, leading to a hypothesis that they served as an intermediate host, much like civet cats did with SARS. As it has with civets, deforestation has dramatically affected the areas available for pangolins’ foraging, putting them in closer contact with other animals including bats, which are reservoirs for other dangerous viruses like Nipah virus, and possibly Ebola. Given our unprecedented mobility, a single “spillover” event, a virus jumping from animal to human, in a remote location can rapidly result in a global calamity like what we are experiencing now. We can accept that outbreaks like Covid-19 will continue to occur, and likely accelerate in number, as human populations grow, as our incursions into a variety of habitats expand and as our penchant for certain animals continues.
