Challenge of the century: Sustainable
Development China imports: • 1/3 of “agriculture
products” • 1/2 of natural gas and oil • Economical issues
• Pollution of Air, Water and Garbage in China is probably one of the worst in the world. (Environmental issues)
• Severe problems in desertification, water and soil erosion, and loss of biodiversity. (Ecological issues)
• The Key Challenge:Imbalance b/w Population + development vs Nature resource supply + regeneration
