We know enough about nature-based solutions already to act on them now. They are critical for climate change mitigation and adaptation and can help avert collapses of healthcare systems and support biodiverse ecosystems, thus reducing risks of infectious diseases. The health sector can meaningfully enhance uptake of nature-based solutions in 3 ways:

1. Recognising humanity's interdependence with nature. We need a paradigm shift in medical curricula, which often do not yet integrate climate change and biodiversity loss.

2. Advocating for policies that advance nature-based solutions. Stakeholders must work together across disciplines and sectors.

3. Expanding the evidence base of the health benefits of nature-based solutions.

Despite the massive impact of nature-based solutions, investment levels are only approximately a tenth of what is required. A comprehensive approach that addresses root causes is needed to avert catastrophic climate impacts and to secure a liveable future. Lack of knowledge should not be used to justify inaction.
