Take a Step, Save the Ocean
Ocean is one of the brilliant habitats that nurture countless species in an interdependent ecosystem.
Every species is important and play a unique role in the whole system. Even the subtlest change in one component may well lead to a chain of events, and at its worst the collapse of the whole eco-system. For example, cownose ray has become more abundant due to overfishing of sharks, the predator of cownose ray. Consequently, the population of scallop declines. Not only was the ecosystem affected, some century-old fisheries were forced to shut down as well.

5 threatened marine species
Few threatened species
Found in tropical waters throughout the world, coral is home to countless species. Pollution and climate change, which might lead to extensive coral bleaching, are the two major threats faced by the species.
Chinese white dolphin
They can be found in the western waters of Hong Kong. Habitat loss, high speed vessel traffic and fishing gear entanglement are threatening their survival, resulting in a continuous abundance decline.
Chinese horseshoe crab
The “living fossils” have been living on earth long before the appearance of dinosaurs. However, the species is experiencing a drastic decline in its juvenile population due to the loss of habitat resulted from coastal development and pollution.
Indo-Pacific Finless porpoise
They live in the eastern and southern waters of Hong Kong with only about 200 remaining individuals. Their population is under threats including high speed vessel traffic and fishing gear entanglement.
A more common seahorse species in Hong Kong.
Seahorses are overexploited as a kind of traditional medicine. They are further threatened by habitat destruction due to marine pollution and coastal development.
