The Rio Earth Summit was highlighted by a speech from then 13 year old Severn Suzuki.
The event was later referred to as “The Girl Who Silenced the World”.

23. The earth summit
The Rio Declaration and Suzuki’s speech reflect the growing perspective of Earth as a single, closed system.
They also reflect the realization that development within the system must be sustainable.

24. Sustainable development
The term ‘sustainable development’ was popularised by the World Commission on Environment and Development (WCED) in its 1987 report entitled Our Common Future.

25. Sustainable development
One of the most important outcomes of Our Common Future was the realisation that environment and development issues are inextricably linked and therefore worrying about either environment or development on its own was inappropriate.

26. Sustainable development
The special contribution of the concept of sustainable development is that it emphasises respect for cultural values and, thus, does not see economic indicators as the sole measure of development.

27. Sustainable development
Rather, sustainable development represents the balanced integration of social and environmental objectives with economic development.

28. Sustainable development
These three aspects of sustainable development – society, environment and economics – were named as the three pillars of sustainable development at the World Summit on Sustainable Development in Johannesburg in 2002.

29. PILLARS Of Sustainable
development
Environment
… an awareness of the resources and fragility of the physical environment and the effects on it of human activity and decisions, with a commitment to factoring environmental concerns into social and economic policy development.

30. PILLARS Of Sustainable
development
Society
… an understanding of social institutions and their role in change and development, as well as the democratic and participatory systems which give opportunity for the expression of opinion, the selection of governments, the forging of consensus and the resolution of differences.

31. PILLARS Of Sustainable
development
Economy
… skills to earn a living as well as a sensitivity to the limits and potential of economic growth and its impact on society and on the environment, with a commitment to assess personal and societal levels of consumption out of concern for the environment and for social justice.

37. reflection Respond to the following reflection questions:
Explain why the Earth can be characterized as a closed system, while parts of it are considered an open system.
What makes the systems model a useful tool for studying environmental impacts? Use excerpts from Suzuki’s speech to support your answer.
The Medicine Wheel of Sustainability holds at the centre “healthy land, healthy nation, healthy people. Discuss how these are interconnected. How might a specific event or action within the environment quadrant affect the three other quadrants?
