By Lin Chia-nan / Staff reporterVoters should support political parties that agree to help protect algal reefs in Taoyuan’s Guantang Industrial Park (觀塘工業區), the Rescue Datan’s Algal Reefs Alliance said yesterday, as it evaluated parties’ responses to the issue. The alliance sent letters to several parties asking if they would promise to demand that the central government extend legal protection to the reefs. Pan also expressed disappointment about the Green Party Taiwan, which replied with revised letters, saying that the party should have demonstrated greater attention for environmental issues. Scientific evidence has shown that the biodiversity in the intertidal zone where the reefs grow is best along Taoyuan’s 27km coastline, Academia Sinica Biodiversity Research Center research fellow Allen Chen (陳昭倫) said. Separately yesterday, the Green Party Taiwan said on Facebook that it revised the letters because it only agreed with certain parts.
