It is these very conditions that facilitate the emergence of new infectious diseases and that also inflict horrific harms on animals — being kept in confined conditions and then butchered. Simply put, the coronavirus pandemic is a result of our gross maltreatment of animals.
Those who think that this is a Chinese problem rather than a human one should think again. There is no shortage of zoonoses that have emerged from human maltreatment of animals. The most likely origin of H.I.V. (human immunodeficiency virus), for example, is S.I.V. (simian immunodeficiency virus), and the most likely way in which it crossed the species barrier is through blood of a nonhuman primate butchered for human consumption. Similarly, variant Creutzfeldt-Jakob disease probably had its origins in its bovine analogue — bovine spongiform encephalopathy (B.S.E.), or “mad cow disease.” The most probable mechanism of transmission is through human consumption of infected cattle.
