Scientist swimming against the tide: Dr Samuel Hung
Dr Samuel Hung is clear on his mission: the dolphins come first. And that means speaking out against officials for failing to protect them
It's a hot, hazy afternoon and a marine biologist is taking a group of reporters out to sea for an update on the plight of Chinese white dolphins.
He lambasts the government, its development plans and what he says is a complete disregard for the animals, which he has been working hard to protect.
For Dr Samuel Hung Ka-yiu, chairman of the Dolphin Conservation Society, it's just another day at the office.
Hung is perhaps the most oft-quoted expert on cetaceans in Hong Kong and one of few willing to openly criticise the government and large corporations for failing to protect what he sees as one of the city's priceless assets.
"I'm not the only dolphin expert or marine biologist in Hong Kong. But I'm guessing journalists come to me because I tell them nothing but the truth," he tells the South China Morning Post. "Too many authoritative experts on dolphins have vested interests and may not necessarily want to speak out too critically against large corporations or the government."
