The Global Deal for Nature (GDN) is a time-bound, science-driven plan to save the diversity and abundance of life on Earth. Pairing the GDN and the Paris Climate Agreement would avoid catastrophic climate change, conserve species, and secure essential ecosystem services. New findings give urgency to this union: Less than half of the terrestrial realm is intact, yet conserving all native ecosystems-coupled with energy transition measures-will be required to remain below a 1.5°C rise in average global temperature. The GDN targets 30% of Earth to be formally protected and an additional 20% designated as climate stabilization areas, by 2030, to stay below 1.5°C. We highlight the 67% of terrestrial ecoregions that can meet 30% protection, thereby reducing extinction threats and carbon emissions from natural reservoirs. Freshwater and marine targets included here extend the GDN to all realms and provide a pathway to ensuring a more livable biosphere.
全球自然协议（GDN）是一个有时限的、以科学为驱动的计划，旨在拯救地球上生命的多样性和丰富度。将 GDN 与《巴黎气候协定》相结合，可以避免灾难性的气候变化，保护物种，并确保基本生态系统服务的安全。新的研究结果使这种联合变得更加紧迫：不到一半的陆地完好无损，但要将平均全球温度上升控制在 1.5°C 以下，就需要保护所有本地生态系统——加上能源转型措施。GDN 的目标是到 2030 年，正式保护地球的 30%，并指定另外 20%为气候稳定区，以保持在 1.5°C 以下。我们强调了 67%的陆地生态区可以达到 30%的保护目标，从而减少自然储备的灭绝威胁和碳排放。这里包括的淡水和海洋目标将 GDN 扩展到所有领域，并提供了确保更宜居生物圈的途径。
