Climate change is impacting health in a myriad of ways, including by leading to death and illness from increasingly frequent extreme weather events, such as heatwaves, storms and floods, the disruption of food systems, increases in infections and food, water and vector-borne diseases, and mental health issues. We need to be ready to deal with an uncertain climatic future and respond to health emergencies quickly.

We live in a world driven by traditional linear economies, where we take resources, make things, consume them, and throw them away. This way of living uses finite raw materials and produces vast waste. In contrast, in a circular carbon economy, things made from carbon, such as chemicals and plastics, are created and consumed in a way that minimises our use of virgin-fossil resources, cuts waste and reduces carbon emissions. We must accelerate our transition to a truly circular carbon economy.

To take a bite out of inequality, health crises, climate change, and ecological destruction, we need sustainable food systems. Given the global population increase, humans have never produced or consumed as much food as we currently do. But how our modern food systems operate is killing us and our planet. Climate change is and will continue to affect all four dimensions of food security: food availability, food accessibility, food utilisation, and food system stability. We must rapidly create more sustainable food systems, from seed to spoon.

Organisations must collaborate with various professional services to foster growth. In planetary health, this involves partnering with patent attorneys, lawyers, accountants, scientific service organisations, trade bodies, financial specialists, and business development experts.
