Commercial fishing’s impact on bird evolution, and the threat of coral eating starfish

The evolutionary impact of commercial fishing on seabirds. Also, how a plague of coral eating starfish is threatening Australia’s Great Barrier Reef.

We look at the impact of climate change, overfishing and pollution on marine eco-systems and examine the scientific solutions to some of those issues. Presented by Joel Werner from the Australian broadcaster ABC Radio National, the series focuses on the improvements both for marine life and the people who depend on oceans for their livelihoods.

In the third programme Joel looks at how data analysis has helped reduce deaths of seabirds caught up in commercial fishing operations. He hears how the same operations may have also had an evolutionary impact on the birds. He looks at the effects of a plague of coral eating starfish on Australia’s Great Barrier Reef.  And he hears how undersea volcanic activity near Papua New Guinea is providing clues about the future direction of ocean climate change.
