Photographer documents how we are killing our oceans
Six decades spent capturing what's beneath the waves has shown photographer how badly marine life is treated but also how beautiful it is
Sixty years of diving have shown David Hsiung Bing-kuan the most beautiful things in the ocean - and the ugliest.
In a career that has taken him across much of the South China Sea, the 73-year-old scuba diver and underwater photographer has seen and photographed stunning vistas as well as "dead zones" created by poison and dynamite used in illegal fishing.
The practice did not just damage the ecology, but once almost took his life when he accidentally swam into a blast zone.
"I could feel the powerful pressure and my heart felt as though it was being pulled out of my body," he said.
The worst destruction he remembers was in Hainan in the 1980s. "I had thought this was going to be a fish paradise, but it turned out the sea was dead. The only living zone was around a pier where dynamite fishing was banned as the facility was near an oil pipe," he said.
