Pshe cas saving the pink dolphins

  1. 1. Saving the PinkDolphinsBy Daniel Liu and Hank Ng 10Eand Jack Tsien 10N and RafaelPang 10D, Chun Yiu Yu 10~
  2. 2. Introduction Pink DolphinsThe Pink Dolphin (Sousa Chinensis Chinensis) is a species of Humpback Dolphin. Pink Dolphins canbe white or pink as it matures, but most of the dolphins in Hong Kong are pink. This is a result of itsoverdeveloped blood vessels which is ideal for thermoregulation. This humpback dolphin has anunusual diving posture, first lifting its beak out of the water and arching its back, and then pausingbefore dipping below the surface or flipping its tail to dive. Male pink dolphins measure up to 3.2metres and females up to 2.44 metres. The weight of the dolphin ranges from 150 to 200 kg.Observers can sometimes see small groups of around three to seven dolphins swimming together in apod. Their average speed is 4.8 km/hr which is quite slow. However, they slap the surface of the waterwith tail when jumping out of the water and they raise their heads vertically out of the water and sinkbelow the surface silently. The dolphins prefer to consume fish that can be directly swallowed,however, their diet depends mainly on their distribution. Natural predators include sharks and killerwhales. On the IUCN (International Union for Conservation of Nature) list, these dolphins are underthe Near-Threatened category. The Pink Dolphins that we are concerned about are the dolphins thatinhabit the Pearl River Estuary located in the vicinity of Hong Kong. The locals of Hong Kong call themthe “白海豚” or”烏忌白忌/乌忌白忌”.Currently, there are approximately 2,500 Pink Dolphins in Hong Kong. The human threats of the PinkDolphins are over-fishing, entanglement in fish nets, water pollution (causing both habitat loss anddiseases when breathing in), coastal development and heavy marine traffic. This species of dolphinsprefer the coasts and therefore, coastal development affect their population numbers.
  3. 3. Our GoalsWe aim to:● Make the waters of Hong Kong and the Pearl Riverdelta cleaner so we can preserve what remains of thecoral reef in Hong Kong● Reduce marine traffic or decrease water pollution, sothat the fish we consume wont be polluted.● Make Hong Kong a more sustainable place.● Re-introduce more pink dolphins to the vicinity of HongKong.● Raise the awareness that the population of pinkdolphins is diminishing● Save the pink dolphin
  4. 4. Our Values● Make the waters of HK and Pearl River delta cleaner so we can preservewhat remains of the coral reef in Hong Kong.● Reduce marine traffic or decrease water pollution, so that the fish weconsume and other predators wont be polluted.● Make HK a more sustainable and environmentally aware place● Re-introduce more pink dolphins into the vicinity of HK.● Raise the awareness that the population of pink dolphins is diminishing● Save the pink dolphins
