特稿|戴青丽:填补生物多样性融资缺口,绿色金融催化全球可持续发展
Di Yi Cai Jing· 2025-06-18 01:28
生物多样性的紧迫性 例如,授粉者数量减少正威胁着全球粮食生产,毕竟约75%的农作物都依赖授粉。生物多样性丧失会破坏土壤健 康、降低水质,还会导致局部气候不稳定,而这些恰恰是人类发展和经济韧性所不可或缺的基础。 此外,对自然生态系统的干扰增加了人畜共患疾病传播的风险。这些疾病的暴发往往与环境恶化、森林砍伐以及 非法野生动物贸易直接相关——而这些都导致生物多样性锐减的严重后果。 与此同时,我们正面临一个越发凸显的悖论。减缓气候变化对于地球上生命的存续至关重要,然而,若管理不 慎,有时反而会加剧生物多样性的丧失。比如,风电厂和太阳能园区等可再生能源基础设施的快速扩张,如果忽 视生物多样性保护,就可能无意间破坏候鸟的迁徙通道,或是损害脆弱的沙漠和海洋生态系统。因此,协调气候 目标与生物多样性目标,已不再是可有可无的选择,而是势在必行的举措。 我们亟须开展一场全面的全球行动,把生物多样性保护提升到与脱碳工作同等紧迫、同等具有战略意义的高度。 这不仅要求各方在政策层面加强协调配合,还需要在金融领域进行创新,推动机构之间的合作,并同时引导私营 部门参与其中。 全球认可与政策进展 生物多样性在全球稳定中所发挥的作用正得到越来 ...
