At that time, they didn’t know the scale of the problem. By recognizing the interconnectedness of natural systems and human activities, the integrity and resilience of ecosystems can persevere in the face of challenges like climate change, habitat degradation and over-exploitation. But in 1985, a hole was confirmed in the ozone layer over antarctica.
