===They are the friendliest of the five sub-species of dolphins and it is reported that their pink coloration is due to the large amount of crustaceans that they consume. It is reported that their numbers are decreasing at a rate of 10% per year with the biggest problem being degradation and pollution of their natural environment. River pollution is one of the most serious causes, with gold mining spewing out large amounts of mercury as a by-product of the mining process. This is killing the pink dolphins at a fast rate.=== ===The increased traffic upon the waterways destroys the pink dolphins' delicate guidance and navigation system, resulting in many accidental deaths of this magnificent creature. The construction of several dams along the waterways will result in the dolphin groups being cut off from one another, further lowering their breeding rates.=== ===Fishing is another cause of pink dolphins becoming endangered. The dolphins become entangled in the fisherman's nets and the fishermen view them as competition for their catch. They either drown as a result of becoming entangled in the nets or they are killed by the fishermen to prevent them eating all their fish.===
 * ===Pink dolphins are only distantly related to their ocean going cousins and live in the rivers of the Amazon rain-forest and can also be found in the Orinoco and Madeira rivers in South America and in the Pearl River in Hong Kong.===
 * ===As with most every other endangered species on our fragile planet, the finger can be pointed squarely at people. Man and his impact upon the environment is directly to blame for the endangerment of this unusual and beautiful mammal.===

The reasons why pink dolphins have become endangered are many and we can only hope that man will see the error of his ways before these amazing creatures are forced into extinction.
=== |||| **White Dolphin, with a local name of White Cow, is a member of the 79 cetacean families, distributed in South Africa, Australia, and along the coastline of China up to the area around Yangzi Jiang. The Hump-backed Dolphins living in Southeast Asia have their unique colour - they are deep grey in colour at birth, and as they grow, the colour becomes lighter until they become white or light pink.** **Most of the Chinese White Dolphins live along the coast and in river mouths, such as the outlet of Zhujiang, where sea water and river water meet. The Chinese White Dolphins in Hong Kong waters are mainly found in Deep Bay, Sha Chau, Lung Kwu Chau, Lantau Island and the west of Lamma Island.**  ** ===The waters around Sha Chau and Lung Kwu Chau are the main habitat of Chinese White Dolphins in Hong Kong. To protect this important habitat, the Government has designated the area, waters of 1200 hectares, as Sha Chau and Lung Kwu Chau Marine Park in November 1996, in accordance with the Marine Park Ordinance (Chapter 476). Inside the park, Chinese White Dolphins can avoid threats such as being hit by high-speed ships and being hurt in destructive fishery activities like shrimp trawling and double trawling.===

 * According to the statistics from the Agriculture, Fisheries and Conservation Department, the Chinese White Dolphins living around the outlet of Zhujiang (including Hong Kong waters) amount to around 1000. However, according to the report on the investigation carried out in Hong Kong by Hong Kong Dolphinwatch, the number of Chinese White Dolphins found in Hong Kong waters (excluding Zhujiang Delta) is estimated only to be about 100 to 150.

===To improve water quality and reduce possible threats caused by toxic pollutants in the water (e.g. heavy metals, fertilizer DDT, etc.), the Government is setting up a series of waste disposal system and upgrading the existing sewage treatment facilities.===

===The Agriculture, Fisheries and Conservation Department deploys artificial reefs in marine parks and other sites in order to rebuild the local fish stock and therefore enhance the availability of the dolphins' preys. We are also formulating a fisheries resources conservation and management plan to rectify the over-exploitation situation and to promote the sustainable development of the fishing industry.===

===A comprehensive conservation programme for the Chinese White Dolphins has been prepared. It specifies the conservation of the Chinese White Dolphins in the outlet of Zhujiang so that they can continue to use Hong Kong waters as their habitat.===
