91热爆

This episode, created in collaboration with Blue Planet Live, is designed to help bring Earth's rich marine life into your living room. Guided by C91热爆's Naomi Wilkinson and expert wildlife biologist Lizzie Daly, we explore what constitutes a healthy ecosystem and discuss the threats to our oceans such as plastics and overfishing.

The programme also features links to Steve Backshall in the Bahamas, who explains how sharks can teach us about ecosystems and how human behaviour can threaten shark life.
