Core Viewpoint - The local government has implemented a ban on beachcombing activities in Beihai Xia Village to protect the ecological environment and allow the coastal ecosystem to recover, following years of overexploitation and environmental degradation caused by tourism and illegal fishing practices [10][12]. Group 1: Environmental Impact - The use of destructive fishing gear, such as fine-meshed nylon nets, has led to significant ecological damage, particularly affecting the population of horseshoe crabs, a nationally protected species [3][5]. - The increase in beachcombing tourism has resulted in a decline in marine biodiversity, with many small marine organisms being collected indiscriminately by tourists, which disrupts the food chain for migratory birds [5][6]. - The activities of tourists, including digging and driving vehicles on the beach, have created physical barriers that hinder the movement of juvenile horseshoe crabs and other marine life, leading to increased mortality rates [3][5]. Group 2: Economic and Social Dynamics - Initially, local villagers engaged in beachcombing tourism cooperatively, setting a unified price of 38 yuan, which fostered a sense of community and ecological responsibility [6][8]. - The influx of external businesses has disrupted this cooperative model, leading to price wars and a focus on profit over ecological sustainability, resulting in a decline in local community cohesion [8][10]. - The local government's ban aims to restore the ecological balance and provide a respite for the beach ecosystem, with hopes for improved management practices in the future [10][12].
