Lorna Benton and colleagues argue that including planetary health in guidance for researchers would help to prioritise effective responses to current environmental and human crises Human activity has pushed Earth’s natural systems beyond safe and just planetary boundaries, creating threats to human health and survival (box 1).1 Evidence shows that six out of nine identified planetary boundaries have already been breached: climate change, novel entities (including synthetic chemicals), freshwater, biosphere integrity, land use, and biogeochemical (nitrogen and phosphorus) flows.3 Surpassing these thresholds will detrimentally alter environmental exposures that affect health outcomes through multiple pathways, both direct, such as changes to heat exposure or air pollution, and indirect, such as effects of population displacement.2 Box 1 ### Planetary boundaries Planetary boundaries are interconnected, so breaching a threshold for one boundary could increase risk in other domains. For example, climate change is a major driver of biodiversity loss.RETURN TO TEXT Net zero targets have incentivised widespread design of climate mitigation actions from local to national levels. Global action and commitment to reverse transgressions in planetary boundaries is increasing, with much effort focused on reducing greenhouse gas (GHG) emissions. But the scale of ambition and implementation is still not commensurate with the urgency needed to prevent catastrophic climate change. Counterarguments often focus on costs, uncertainty of effectiveness, or concerns about trade-offs, including for inequity. Perceived public support may also inform which interventions are considered acceptable or feasible in any setting and is influenced by near term effects such as …

在气候和健康复杂干预措施的指导中需要从地球健康的角度出发

Lorna Benton 及其同事认为，将地球健康纳入研究人员的指南中，将有助于优先考虑对当前环境和人类危机的有效反应。人类活动已将地球的自然系统推向了安全和公正的地球边界之外，对人类健康和生存构成了威胁（框 1）。有证据表明，在已确定的九个地球边界中，有六个已经被突破： 气候变化、新实体（包括合成化学品）、淡水、生物圈完整性、土地利用和生物地球化学（氮和磷）流动.3 超过这些阈值将有害地改变环境暴露，这些影响通过多种途径影响健康结果，既有直接的，如热暴露或空气污染的变化，也有间接的，如人口流离失所的影响.2 框注 1 ### 地球边界 地球边界是相互关联的， 因此，突破一个边界的阈值可能会增加其他领域的风险。例如，气候变化是生物多样性丧失的主要驱动因素。返回正文净零目标激励了从地方到国家层面广泛设计气候缓解行动。全球采取行动和承诺扭转地球边界的违规行为，并大力减少温室气体 （GHG） 排放。但雄心壮志和实施的规模仍然与防止灾难性气候变化所需的紧迫性不相称。反驳通常集中在成本、有效性的不确定性或对权衡的担忧上，包括对不公平的担忧。感知到的公众支持也可能告知哪些干预措施在任何环境中被认为是可以接受或可行的，并受到近期影响的影响，例如......
