Episode Overview

Coral reefs, known for their stunning beauty, serve as vital habitats for more than 25% of marine species and play a significant role in human communities worldwide. However, rising ocean temperatures and climate change are leading to widespread coral bleaching and reef decline. In response, a global coalition of marine researchers is uniting to tackle this crisis through a method known as assisted evolution. Join these dedicated scientists as they work to hybridize heat-tolerant corals and transfer algae from one species to another, striving to prevent the extinction of these essential underwater ecosystems.
