摘要

单独评估塑料污染、气候变化和生物多样性丧失这三个相互关联的问题,可能会忽略可能对全球生态系统过程产生积极或消极影响的潜在相互作用。最近的研究表明,受威胁的物种和生态系统容易受到塑料污染和气候变化压力的影响。在这里,我们以全球南方为重点,考虑这三个环境问题之间的联系和知识状况。在长期气候风险指数(CRI)(2000-2019)排名前十的国家中,有九个位于全球南方,但研究的重点是全球北方。对排名前10位的长期气候风险指数(CRI)(2000-2019)国家的文献检索发现,共有2416个(占全球出版物的3.3%)关于气候变化的搜索结果相匹配,其中56个(占全球出版物的4%)关于塑料污染,7个(占全球出版物的7.7%)关于气候变化和塑料污染。全球南方与高生物多样性热点、高粮食不安全和低环境绩效之间存在很强的相关性。以孟加拉国为例,我们展示了侵蚀率和海平面上升的情景,这些情景将增加海洋塑料污染并影响生物多样性高的地区。减轻贫困和促进可再生能源和绿色做法可以大大减少对环境的压力。我们建议,要解决这些相互关联的地球威胁,最好的办法是采取全面合作的研究方法,关注全球南方,制定雄心勃勃的政策议程。

The ecological impact of plastic pollution in a changing climate.

Assessing three interlinked issues, plastic pollution, climate change and biodiversity loss separately can overlook potential interactions that may lead to positive or negative impacts on global ecosystem processes. Recent studies suggest that threatened species and ecosystems are vulnerable to both plastic pollution and climate change stressors. Here we consider the connectivity and state of knowledge between these three environmental issues with a focus on the Global South. Nine out of top ten Long-Term Climate Risk Index (CRI) (2000-2019) ranked countries are located within the Global South, yet research is focused in the Global North. A literature search for the top ten Long-Term Climate Risk Index (CRI) (2000-2019) ranked countries matched a total of 2416 (3.3% of global publications) search results on climate change, with 56 (4% of the global publications) on plastic pollution, and seven (7.7% of the global publications) on both climate change and plastic pollution. There is a strong correlation between the Global South and high biodiversity hotspots, high food insecurity and low environmental performance. Using Bangladesh as a case study, we show the erosion rates and sea level rise scenarios that will increase ocean-bound plastic pollution and impact high biodiversity areas. Poverty alleviation and promoting renewable energy and green practices can significantly reduce the stress on the environment. We recommend that these connected planetary threats can be best addressed through a holistic and collaborative approach to research, a focus on the Global South, and an ambitious policy agenda.
