ABSTRACT
Key concepts for sustainability education:
Population growth, which implies an increasing demand for limited resources, is predicted to continue to increase and reach 10.9 billion at the end of the century.
Environmental as well as social problems will intensify as population growth increases the demand for resources in a world of finite resources.
The need to feed a growing population has increased the global ecological footprint to 21.2 billion global hectares, which now exceeds the estimated world’s biocapacity by 65%.
Reduction and stability of population size are critical to ensure an essential balance between population resource demands and the ability of the world to provide for those demands.
Reduction of population size would be associated with an increase in the well-being of global citizens and ensure better intergenerational equity of global resources.
