Why are the families starving? Is the only option in that area growing cocoa for export to the West? Why can't those people work for themselves, to grow their own food, to feed themselves?
Is it because some wealthy landlord owns all the land? Is it because we dump subsidized food on the global markets, making local agriculture non-competitive? Could either of those have anything to do with it?
There seems to be a very obvious economic solution somewhere between 'grow cocoa for other people for a pittance' and 'starve'. These people are poor, not helpless.
