Three main goals of sustainability:
1. Environmental health
2. Economic profitability
3. Social and economic equality
Systems that the Earth consists of are the biosphere, atmosphere, hydrosphere and
geosphere.
Biosphere – regions of the surface of our earth occupied by living organisms
• Ecosystems
• Evolution by natural selection
• Biodiversity
• Biogeography
• Life in the oceans
Geosphere – soil is the interface between all systems
• Plate tectonics
• Rock cycle
• Biogeochemical cycle
Effects:
• Agriculture
• Mineral extraction
• Urbanization
Atmosphere – envelope of gases surrounding the Earth
• Atmosphere composition
• Climate
Hydrosphere – all the water on and above Earth’s surface
• Water pollution
• Water use
UNDERLYING THEMES
-human population
-sustainability
-bio mimicry
-global perspective
-urban world
-values, ethics & knowledge

Document Summary
Three main goals of sustainability: environmental health, economic profitability, social and economic equality. Systems that the earth consists of are the biosphere, atmosphere, hydrosphere and geosphere. Biosphere regions of the surface of our earth occupied by living organisms: ecosystems, evolution by natural selection, biodiversity, biogeography, life in the oceans. Geosphere soil is the interface between all systems: plate tectonics, rock cycle, biogeochemical cycle. Effects: agriculture, mineral extraction, urbanization, atmosphere composition, climate. Atmosphere envelope of gases surrounding the earth. Hydrosphere all the water on and above earth"s surface: water pollution, water use.
