Food is one of the most important commodities to sustain human life. Our amount of food in this world is technically sufficient for the entire population, but the distribution is not even. That is there are still starvation and famines in some countries but a large amount of food wasted in other countries.
My sketch of the grain barn or known as the grain elevator is a sign of the surplus of production. Life is plentiful, but we humans are greedy for more gains.
