"Today, banks and other investors, as well as dedicated investment funds established as subsidiaries of the ABCDs themselves, have invested billions of dollars in food commodities with no interest in taking possession of any physical commodity," the report reads.
This is what is referred to as the "financialization" of the food commodities market, which essentially means that the ABCDs have a great deal of control in influencing the prices of the products they are trading in, as well as the ability to hedge on their investments to forestall market volatility.
This is particularly troublesome in times of low food production -- which is becoming more common as climate change causes worse droughts and harsher weather conditions -- because the ABCDs have no incentive to keep food prices affordable despite humanitarian concerns.

That 85% sensitivity when the ugly duckling sign was applied by non-clinicians is much higher than the percentage seen in studies of the ABCD method, Dr.
