That's actually all there is to Soylent Green: the population has grown too large, and in order to feed everyone, people eat "synthetic" food, but it turns out the synthetic food is made of people. The movie's plot has something to do with a detective investigation, and class dynamics, and a romance, but really, all anyone needs to know is: Swift, but with corporations.

Childhood's End is the one where a planet has a ZPM that runs a shield, but the shield is too small to accommodate a large population so as soon as people turn 25, they commit suicide. Of course, Our Heroes (tm) are appalled by this and "fix it" so that people can live past 25. It's a lot like that TNG episode Half a Life, where people committed suicide when they reached 60 so no one had to care for the elderly.
