The COVID-19 pandemic has brought humanity's strained relationship with nature into sharp focus, with calls for cessation of wild meat trade and consumption, to protect public health and biodiversity. However, the importance of wild meat for human nutrition, and its tele-couplings to other food production systems, mean that the complete removal of wild meat from diets and markets would represent a shock to global food systems. The negative consequences of this shock deserve consideration in policy responses to COVID-19. We demonstrate that the sudden policy-induced loss of wild meat from food systems could have negative consequences for people and nature. Loss of wild meat from diets could lead to food insecurity, due to reduced protein and nutrition, and/or drive land-use change to replace lost nutrients with animal agriculture, which could increase biodiversity loss and emerging infectious disease risk. We estimate the magnitude of these consequences for 83 countries, and qualitatively explore how prohibitions might play out in 10 case study places. Results indicate that risks are greatest for food-insecure developing nations, where feasible, sustainable, and socially desirable wild meat alternatives are limited. Some developed nations would also face shocks, and while high-capacity food systems could more easily adapt, certain places and people would be disproportionately impacted. We urge decision-makers to consider potential unintended consequences of policy-induced shocks amidst COVID-19; and take holistic approach to wildlife trade interventions, which acknowledge the interconnectivity of global food systems and nature, and include safeguards for vulnerable people.
COVID-19 大流行使人类与自然的紧张关系成为焦点,呼吁停止野生动物贸易和消费,以保护公共卫生和生物多样性。然而,野生动物对人类营养的重要性,以及其与其他食品生产系统的紧密联系,意味着将野生动物从饮食和市场中完全去除将对全球食品系统造成冲击。在应对 COVID-19 的政策中,应该考虑到这种冲击的负面影响。我们表明,由于食品系统中突然的政策导致野生动物的缺失,可能会对人类和自然造成负面影响。饮食中野生动物的缺失可能导致粮食不安全,因为蛋白质和营养减少,或者为了用动物农业替代失去的营养而导致土地利用变化,这可能会增加生物多样性的丧失和新发传染病的风险。我们评估了这些后果在 83 个国家的严重程度,并定性地探讨了在 10 个案例研究地点中禁令可能产生的影响。结果表明,对于粮食不安全的发展中国家来说,风险最大,因为在这些国家,可行、可持续和社会可接受的野生动物替代品有限。一些发达国家也将面临冲击,尽管高容量的食品系统可以更容易地适应,但某些地方和人群将受到不成比例的影响。我们敦促决策者在 COVID-19 期间考虑政策冲击带来的潜在意外后果;并采取整体方法来干预野生动物贸易,承认全球食品系统和自然的相互联系,并为弱势群体提供保障。
