Four decades of Hawaiian monk seal entanglement data reveal the benefits of plastic debris removal 四十年來夏威夷僧海豹纏繞的數(shù)據(jù)揭示了清除塑料碎片的好處 ▲ 作者：JASON D. BAKER, THEA C. JOHANOS et al. ▲ 鏈接：https://www.science.org/doi/10.1126/science.ado2834 ▲摘要：廢棄漁具會對海洋物種和生態(tài)系統(tǒng)造成危害。為了減輕這些海洋塑料碎片造成的破壞，已經(jīng)建立了各種清理計(jì)劃。但據(jù)我們所知，這些努力對海洋物種和生態(tài)系統(tǒng)的好處尚未得到實(shí)證證明。 我們研究了在西北夏威夷群島開始大規(guī)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纏繞記錄，表明在垃圾清除工作最集中的地方，纏繞率大幅降低。大規(guī)模、持續(xù)地清除廢棄漁具對海洋生態(tài)系統(tǒng)有益，并有可能改變生態(tài)恢復(fù)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. |
