  12. Urbanization: Mega-Cities • Megacities today • Cover just 2% of the Earth’s land surface • 75% of industrial wood use • 60% of human water use • Nearly 80% of all human produced carbon emissions • Megacities tomorrow • By 2025 more than 300 cities worldwide will have more than 1 million people • The struggle to achieve an environmentally sustainable economy for the 21st century will be won or lost in the world's urban areas Map source: www.channelone.com IIIIII Source: www3.sympatico.ca/truegrowth/demographics.htm

  13. Global Population: Rising Demand for Resources • Too Many (especially in developing world) • Too Old (especially in developed world) • Too Urban (globally) • Global Migration

  14. Population and Human Development Needs Of 6.5 billion people in the world today 1.6 billion lack basic energy services 2.5 billion use wood, dung or other biomass to cook their food 2.6 billion people lack access to clean water and sanitation By 2050, almost 2.5 billion people will be born. Is there enough to go around? IIIIII

  22. the greenhouse gas emissions arising every year from the production and consumption of cheeseburgers is roughly the amount emitted by 6.5 million to 19.6 million SUVs

  23. "In a world where an estimated one in every six people goes hungry every day, the politics of meat consumption are increasingly heated, since meat production is an inefficient use of grain …... Continued growth in meat output is dependent on feeding grains to animals, creating competition for grain between affluent meat eaters and the world's poor.” Worldwatch Institute IIIIII
