Marine life, habitats, and ecosystems have a chance to recover within 30 years according to a new study in Nature. While this would require huge conservation efforts and major policy changes, we have the knowledge to make this happen by 2050. The researchers cited a series of smaller conservation success stories, like the Humpback Whale in Eastern Australia, the Sea Otter in Western Canada, and Green Turtles in Japan along with the incredible resilience of marine life as evidence. Centuries of overfishing, pollution, and coastal destruction have caused massive declines in marine biodiversity. However, one of the main messages from the study is that ocean biodiversity is resilient. If we stop killing marine life and double down on conservation efforts, they can bounce back. There are three key actions needed to make this happen across the globe.
