The report seems to say "Ethanol-use makes global warming worse. To make cereals, many forests which take in CO2 will be vanished. As a result, CO2 increases substantially.".
As I said, Japan will proceed ethanol vapour made of weeds in 2 years, already is proceeding ethanol vapour made of scrap woods. perhaps, Japan's one is no problem. We can use thinned wood too and cutting thinned wood is good for forest. That rice for bio-fuel is not beautiful. My aesthetic feeling doesn't accept it.
Cars can be turned to Hybrid car, electric car and hydrogen car etc. But we, human, need cereals. Skyrocket of dietary item's price may cause riots in the world. That is, Bush's policy is wrong if the report is right. Bush is a hasty man?
I took the photo.
