Environmental Dimension 4/23/2012 11

Environmental Management Atmosphere: Freshwater and oceans: Land use 4/23/2012 12

Energy 4/23/2012 Water Food Materials 13

Management of Human Consumption Energy Plants grow making sugars, cellulose and complex molecules from simple raw materials, mostly water, CO 2 and sunshine. 4/23/2012 In addition to harvesting food, people extract fuel and base materials for industry and commerce. Manufactures make wares, measuring profitability in environmental and social terms as well as financial. The end user reuses and repairs, only recycling after as long a useful life as possible. At the end of its life the article decays, reducing large complex molecules to simple raw materials by the action of bacteria and fungi composting. Plants grow making sugars, starches, oils, cellulose and complex molecules from simple raw materials, mostly water, CO 2 and sunshine. 14

Economic Dimension Decoupling environmental degradation and economic growth: The bio-economy needs to decouple the historical relationship between economic growth, energy use and environmental degradation 4/23/2012 18

Economic Dimension Nature as an economic externality: 4/23/2012 19

Economic Dimension Economic Opportunity: Treating the environment as an externality may generate short-term profit at the expense of sustainability The triple bottom line (also known as the three pillars) 4/23/2012 20

Social Dimension Peace, security, social justice: -> environmental security -> global environmental agreements Sustainability and poverty: As population growth continues to increase, increasing pressure is being placed on the local ecosystem to provide these basic essentials. 4/23/2012 21

Social dimension Human relationship to nature: humans must dominate nature is a common idea in hierarchical societies Human settlements: ->approach to sustainable living (small-scale urban transition towns and rural eco-villages) -> seek self-reliant communities based on principles of simple living http: //www. youtube. com/watch? v=B 5 Ni.
