While health has improved for many, the extent of health inequities between and within countries is growing. Meanwhile, humankind is disrupting the global climate and other life-supporting environmental systems, thereby posing serious risks to health and well-being, especially in vulnerable populations but ultimately for all. The underlying determinants of health inequity and of environmental change overlap substantially. They reflect, in particular, an economic system predicated on asymmetric growth and competition, shaped by market forces that mostly disregard health and environmental consequences and limits rather than by values of fairness and support. A shift is required in priorities in economic development, healthy forms of urbanisation, more efficient and renewable energy modes and a sustainable and fairer food system. Addressing the social determinants of health will not only improve global health, but advances will also be made in poverty eradication and social equity such that people, communities and nations will be able to resist current climate change and avert further damage to the global environment and climate. This paper will explore in particular the issues of economic development, urbanisation and food systems in the context of global health equity and climate stabilisation
