Tai O Field Trip

Introduction:
I participated in a field trip to Tai O earlier. Before writing this report, I must first thank the teachers for organizing this extremely meaningful field trip. In this journey, I not only learned many of Tai O’s traditional culture, but also reflected on the balance between conservation and development. In the following, I will describe three parts that I think are very interesting during this journey.

Facts of Tai O:
Tai O is a famous fishing village located in the western part of Lantau Island, Hong Kong. People lived here very early, and the original residents were “Tanka people”. Tai O was their place of residence for generations. Their main occupation is fishermen. From the beginning of the Song Dynasty, there was also

It is therefore an honour to have the chance to see the habitat of Chinese White Dolphins this time.
At present, there are about 2,500 Chinese white dolphin inhabiting Hong Kong, and this number has continued to decrease in recent years.
The tour guide leading us told us that the construction of the Hong Kong-Zhuhai-Macao Bridge did pose a threat to the living environment of this lovely mammal. In addition, many yachts ignored the safety rules and passed through the waters at high speed, causing injuries to the dolphins. It also scares many of the same species and keeps the Chinese white dolphins away from Hong Kong waters. Of course, we must mention over-fishing, water pollution, etc., it also destroy their ecological environment.
B. Feeling:
This is my first visit to Tai O, but it is not the first time I have tried to watch the Chinese White Dolphins. Before this time, I had several opportunities to watch the Chinese white dolphins, but I could not see any dolphins. Therefore, my viewing this time is also holding a profitable mentality. Fortunately, the weather is well and the dolphins were also "cooperating" with us. When our ships sailed into the waters, they all jumped out of the water and surfed gracefully. I am very honored to be able to see their wonderful Hong Kong

Otherwise, it will be too late to make any remedial measures when their numbers are reduced or even extinct.
Mangrove
A. Facts and Finding:
Mangroves are a unique ecological environment. They are generally found in the estuaries of tropical and subtropical regions. The plants that grow there are often washed by the tides and rivers and form a unique growth pattern.
In fact, the ecological environment of mangroves can be said to be very harsh for the general plants: the salinity of the water are variable, the soil is loose, and the oxygen is sometimes paralyzed... It can be said that the animals and plants that can finally stand there, All are very "resolute" species.
In Tai O, the mangrove we visited was named "Yantian Mangroves." Its area is not large, but it can already find two of Hong Kong’s eight “red mangrove trees”: Kandelia and Rattus.
The formation of this "Yantian mangrove forest" was due to a previous salt factory in Tai O. After the closure of this manufacturing plant, salt and fresh water flooded into the original salt drying place of the plant, making it slowly evolve into a mangrove forest and enriching the biodiversity of Tai O.
