What?
What happened? A news report says boat traffic and underwater noise in Hong Kong's waters are proving too much for Chinese white dolphins (Sousa chinensis chinensis). Numbers have dropped sharply.
Who?
Who raised the alarm? The Hong Kong Dolphin Conservation Society did. The charitable society was formed in 2003. Its website says it is the only society dedicated to saving Hong Kong's whales, dolphins and porpoises. It wants to raise public awareness about the plight of the dolphins and preserve their habitat.
When?
When were the drops in numbers observed? The society said the fall in dolphin numbers was especially marked in 2003-04 and 2007-08. They coincided with increases in boat traffic. In 2003, the SkyPier ferry terminal opened at Hong Kong International airport. The society's chairman, Samuel Hung, says plans to build a third runway would increase ferry traffic and place further strain on the dolphins.
