You remember last summer when gas was $4 a gallon? It was an unusual thing considering demand had plummeted and there were overflowing storage tanks not just here but around the world. What was driving such high prices? Speculators looking for the next bubble. And now they're looking for their next bubble but this time it's going to be food but to get that food they will need land and that is exactly what they are doing now. Aquiring land like something not seen since the land rushes of days gone by only this land grab makes the ones of the past pale by comparison. Large tracks of land in Africa and Asia in of course poor nations are being bought up at bargin basement prices with the lion's share of the crops leaving the country. The land is being bought right out from under poor farmers who will see little to nothing in return.
I saw a similar situation in Brazil where European nations are backing soy farms for animal feed. The local farmers have been pushed off the land and must rely on handouts from the government that is when the government is feeling generous which isn't too often.
