Corn

Because of the war, Ukraine was unable to ship grain out using the Black Sea so they created a corridor through Romania and Bulgaria. Russia recently attacked three grain ships in this area which means grain coming from Ukraine may be in jeopardy. Under current law 40% of US corn must be used for ethanol. When people start going hungry in parts of the world will it be time to change the law and start using corn as feed. It has already been shown that this way to manufacture fuel is not reducing CO2.
