Environmentalists are concerned that concrete structures are replacing the islands' natural coastlines. Lin said the concrete structures have seriously damaged the tidal zones of Penghu. For decades, the government has been keen on building fishing ports in Penghu in an effort to develop the local fishing industry. According to Penghu County's Construction Bureau, there are 67 ports in 97-village Penghu. Some villages that are joined together and could have shared one port have their respective ports, while some villages have more than one port.
Many ports are just unnecessary.
Also located around the Penghu islands are embankments and land reclaimed from the sea. The land adjacent to the embankment, a strip also several hundred meters long and tens of meters wide, was a large illegal waste dump. Embankments on tidal zones are not only meant to prevent land erosion by the sea but also create places for the soil dug out for ports to be relocated. Chen asked rhetorically. But look, behind many embankments there are wastelands where no one lives.
