    • Sustainablity relies on lilving within only the naurural income generated by natural capital and not using the capital.
    • Sustainable development that meets current needs without comprimising the abilty of future generations to meet their needs and without degrading the environment.
    • The human carrying capacity can be increased by use of technology, reducing energy use or recycling.
    • The ecological footprint of a population is the land area required to sustainabley supprot it and can be calculated.
    • Population growth and ecological frootprint size are influenced by stage of development of a country and by its worldview.
