Hong Kong's 'pink' dolphins under threat from airport and Macau bridge

Conservationists fear Hong Kong's unique dolphins are at risk of disappearing due to loss of habitat and pollution from two major construction projects

Conservationists have warned that projects to expand Hong Kong's airport and build a new bridge to Macau could result in the loss of the city's beloved "pink" dolphins.

Dolphin numbers have declined sharply in Hong Kong harbour over the past few decades, and campaigners fear that the large-scale construction work will drive the mammals away for good.
