Reasons for the increase of hunger according to FAO, State of Food Insecurity 2009 The food price crisis The global economic slowdown Insufficient investment in agriculture The increase is not a result of poor crop harvest Source: policybriefs/multimedia0/presentation-the-state-of-food- insecurity/en/ 10

Findings In developed world, more people die in winter, but trend is downward due to greater wealth and fuel affordability Deaths and death rates from extreme weather events, malaria, hunger, and other climate sensitive health risks have declined over the long term Mortality Rates Life Expectancies GW ranks below the top 20 global health problems today, and will advance only if these other risks are solved first Death and disease from biofuel production more likely to be real than those estimated due to GW Increased death and disease from biofuel production most likely exceeds any reductions from reduced GW 20
Conclusions GW or its underlying human causes (if any) have not increased death and disease in the aggregate. In fact, they are probably responsible for the worldwide decreases in mortality rates and increase in life expectancy over the last century. GW policies may already have killed more than they have saved And may kill even more if they reduce energy use prematurely and/or economic development, particularly for the less well-off 21
