野猪(Sus Scrofa)曾多次被引入世界各地。在适应性生物学和人类刻意引入的帮助下，美国入侵野猪的范围在过去30年里从17个州扩大到38个州。这种猪的多面性饮食，再加上高密度的种群，可能会使保护受威胁和濒危物种的努力复杂化，仅在美国，农作物破坏和牲畜捕食造成的损失估计就超过10亿美元。此外，野猪可能是多种病原体的宿主，其中一些是人畜共患病。管理层通过减少人口数量来缓解这些威胁的措施，面临着来自珍视野猪作为生存或运动狩猎的团体的抵制，这导致了极其分裂和难以实施的复杂政策行动。
Feral swine (Sus scrofa) have been repeatedly introduced to locations around the world. Aided by both an adaptable biology and deliberate introductions by people, the range of invasive feral swine in the United States has expanded from 17 to 38 states over the past 30 years. The swine's generalist diet combined with high population densities can complicate efforts to conserve threatened and endangered species, and losses from crop damage and livestock predation in the United States alone are estimated to be more than $1 billion. In addition, feral swine can be a reservoir for multiple pathogens, some of which are zoonotic. Management responses to mitigate these threats by reducing population numbers face resistance from groups that value feral swine for subsistence or sport hunting, which results in complicated policy actions that are extremely divisive and difficult to implement.
