Document Summary

The lightbulb calculation---over the next 12 years we will be adding 1 billion people. Giving each new person one 60 watt lightbulb: material: 15000 small cars. Energy: each use 4 hours per day, will new 20 new 500 megawatt power plants, with a 10000. To stabilize population: limit population growth, education of women, children not needed for labor, access to family planning, child survival. Ps: kg co2/kg food=g co2/g food; m3/lg=l/kg.

If everyone substituting beans for beef, could reduce about 46-74% of reductions needed to meet the 2020 ghg target for the united states. Demand for empty calories increases with income, yet china is a notable exception. Total demand for calories including waste in also increasing with income. Diets are happening all the time: reduced ruminant mean and diary consumption will be indispensable for reaching the 2 degrees target with a high probability.
