Four decades of Hawaiian monk seal entanglement data reveal the benefits of plastic debris removal 四十年来夏威夷僧海豹缠绕的数据揭示了清除塑料碎片的好处 ▲ 作者：JASON D. BAKER, THEA C. JOHANOS et al. ▲ 链接：https://www.science.org/doi/10.1126/science.ado2834 ▲摘要：废弃渔具会对海洋物种和生态系统造成危害。为了减轻这些海洋塑料碎片造成的破坏，已经建立了各种清理计划。但据我们所知，这些努力对海洋物种和生态系统的好处尚未得到实证证明。 我们研究了在西北夏威夷群岛开始大规模海洋垃圾清除工作前后40多年的夏威夷僧海豹海洋垃圾缠绕记录，表明在垃圾清除工作最集中的地方，缠绕率大幅降低。大规模、持续地清除废弃渔具对海洋生态系统有益，并有可能改变生态恢复工作。 ▲ Abstract：Abandoned, lost, or otherwise discarded fishing gear causes harm to marine species and ecosystems. To mitigate the destruction wrought by this ocean plastic debris, various cleanup programs have been established, though to our knowledge the benefits of such efforts to marine species and ecosystems have not yet been empirically demonstrated. We examined more than 40 years of Hawaiian monk seal marine debris entanglement records before and after large-scale marine debris removal efforts were initiated in the Northwestern Hawaiian Islands, demonstrating a substantial reduction in entanglement rates where debris removal effort was most concentrated. Large-scale and sustained removal of abandoned, lost, or otherwise discarded fishing gear meaningfully benefits marine ecosystems and has the potential to be transformational in restoration efforts. |
