Cassava for biofuels?

It’s bad enough that corn is grown for ethanol, but cassava?  Many populations depend on cassava for food.

According to today’s New York Times, cassava is the new “go to” crop to burn for fuel.  Doing this, of course, prices cassava beyond what people can afford:

It can be tricky predicting how new demand from the biofuel sector will affect the supply and price of food. Sometimes, as with corn or cassava, direct competition between purchasers drives up the prices of biofuel ingredients. In other instances, shortages and price inflation occur because farmers who formerly grew crops like vegetables for consumption plant different crops that can be used for fuel.

The Times graph of the increase in use of food for biofuel is sobering:

None of this makes sense to me.  We need a sensible food policy and a sensible energy policy.
