It's a weird world, seeing for example hungry people in Ethiopia and on the other hand German companies occupying 32.000 acres for biofuel and India growing flowers and other food there... Or in the Republic of Congo where China has 7 million acres to produce biofuel...
According WFP (world food program) these countries in Africa have the highest rate of unnourished people.
I know, the answer is simple: plain greed!
It's sad to see it's all for biofuels, as there are heaps of alternatives; take your bike!!!
