Antarctica is considered one of the Earth's largest, most pristine remaining wildernesses. Yet since its formal discovery 200 years ago, the continent has seen accelerating human activity. Reporting in the journal Nature, a research team including Tilburg University show where human activities have been conducted and uncover two main concerns: wilderness in Antarctica is decreasing due to an increasing "human footprint" and biodiversity is under pressure because species mainly depend on areas that are strongly influenced by humans. However, much opportunity exists to take swift action.
