When I first came to Shenzhen, my family would take me to the mangroves to see waterfowl, the birds not only beautiful and has large number of waterfowl. But in 2014, the global synchronization of coastal waterfowl survey data show that Shenzhen's waterfowl continued to decrease in the number of this year compared to last year's, 17 percent reduction, especially in the most talked about rare birds black-faced spoonbill, this year only recorded 252.(SZ NEWS,2014) Ecological change and human disturbance or changes in the status of the most important reason birds. A large number of human beings will go to see birds, leading to an artificial environment pollution; and, soil and water quality to deteriorate, along with the deterioration of the ecological environment.
