Over-fishing is a massive environmental and economic challenge. Fortunately, there are new solutions being trialled – including in a tuna hotspot in the Pacific.

A rash of white shark attacks this summer points to a rebounding population in the US – a sign of healthier oceans and the need to coexist with this apex predator.
To create accurate models that predict how ice sheets and oceans will react to changing climate, modelers need precise current data. One researcher heads to the ends of the earth to collect just that.
Although frightening, the footage of Mick Fanning at Jeffreys Bay is a reminder that sharks are present in the oceans, and that the vast majority of interactions between people and sharks end without fatality or injury.
