Rationale

It's the year 2022... People are still the same. They'll do anything to get what they need. And they need SOYLENT GREEN.
That's a tagline from the 1973 film, titled appropriately enough, "Soylent Green". It took its name from one of the most nutritious of the Soylent (Soy+Lentil, get it?) line. Soylent Red and Yellow could never match the zest and delicious aftertaste of their Green cousin. Fresh food is a luxury, and the "high energy food concentrates" from the Soylent Corporation feed the masses. The Green version is supposed to be made from plankton, and it quickly becomes the favorite among the food-wafer consuming crowd. Couple this with a government sponsored euthanasia program, and you've got the beginnings of a real ugly little food chain, as our hero discovers.
How sad that Chuck Heston didn't live to see the world food crisis that is presently erupting. It's not 2022, but it might as well be. I have grown used to seeing images of starving people from foreign lands. Weren't we all raised with the need to clean our plates since there was somebody starving in China, or Africa?
Imagine my surprise when I heard on the radio that Sam's Club, a unit of retail giant Wal-Mart, said on Wednesday it was capping sales of rice at four bulk bags per customer per visit. The previous day, rival Costco Wholesale Corp reported mounting demand for rice and flour as worried customers stocked up. In my mind I pictured food riots being dispersed by giant front-loading tractors. And that's when I thought of my chocolate Power Bar. What are those things made of, anyway?
