Ethics of Killing Invasive Animals

Not every species introduced by humans becomes a problem – but some do, especially on islands. In this episode of Inside Biodiversity, invasion biologist Marten Winter (iDiv and Leipzig University) explains how we define alien vs. invasive alien species, why the raccoon is a management challenge for Europe, and why management is particularly tricky in places like Australia. We also discuss the ethical dilemmas of controlling species such as the red fox – and whether it is possible to identify non-native species without knowing their origin.
