Are Introduced Species Always Harmful?

What should we really aim for in nature conservation—and who gets to decide? In this episode of Inside Biodiversity, science writer Emma Marris challenges long-held ideas about wilderness, ecosystem integrity, and invasive species. She argues that conservation is driven by human values—not objective science—and calls for a more democratic, transparent approach to setting goals for nature. If you’ve ever wondered whether “naturalness” is an illusion or why change in ecosystems isn’t always a loss, this thought-provoking conversation will make you see biodiversity in a whole new light.
