Following our failure to fully achieve any of the 20 Aichi biodiversity targets, the future of biodiversity rests in the balance. The Convention on Biological Diversity's Post-2020 Global Biodiversity Framework (GBF) presents us with the opportunity to preserve Nature's Contributions to People (NCPs) for current and future generations through conserving biodiversity and averting extinction across the Tree of Life. Here we call attention to our need to conserve the Tree of Life to maintain its benefits into the future as a key mechanism for achieving intergenerational equity. We highlight two indicators available for adoption in the post-2020 GBF to monitor our progress towards safeguarding the Tree of Life. The Phylogenetic Diversity indicator, adopted by IPBES, can be used to monitor biodiversity's capacity to maintain NCPs for future generations. The EDGE (Evolutionarily Distinct and Globally Endangered) Index monitors how well we are performing at averting the greatest losses across the Tree of Life by conserving the most distinctive species. By committing to safeguarding the Tree of Life post-2020, we can reduce biodiversity loss to preserve nature's contributions to humanity now and into the future.

保护进化历史以保护我们的未来：将生命之树纳入生物多样性政策

在我们未能完全实现 20 项爱知生物多样性目标中的任何一项之后，生物多样性的未来就岌岌可危了。《生物多样性公约》的 2020 年后全球生物多样性框架 (GBF) 为我们提供了通过保护生物多样性和避免生命之树灭绝来为今世后代保护自然对人类的贡献 (NCP) 的机会。在这里，我们提请注意我们需要保护生命之树以保持其未来的利益，这是实现代际公平的关键机制。我们强调了 2020 年后 GBF 可采用的两个指标，以监测我们在保护生命之树方面取得的进展。IPBES采用的系统发育多样性指标可用于监测生物多样性' 为子孙后代维护 NCP 的能力。EDGE（进化独特和全球濒危）指数监测我们通过保护最独特的物种在避免整个生命之树的最大损失方面的表现。通过承诺在 2020 年后保护生命之树，我们可以减少生物多样性的丧失，保护现在和未来自然对人类的贡献。
