"There are two interrelated dimensions to the ongoing global food crisis, which has spearheaded millions of people around the World into starvation and chronic deprivation, a situation in which entire population groups no longer have the means to purchase food.
First, there is a long term historical process of macroeconomic policy reform and global economic restructuring which has contributed to depressing the standard living Worldwide in both the developing and developed countries.

These price hikes are in large part the result of speculative trade in food staples. " (Thanks A)
