If you want to explore the concept further, I suggest you watch the movie "Never Let Me Go" (2010). The premise is very similar, apart from the fact there's no secret or conspiracy about it, children are just grown to become sacrificial organ donors, and since it's socially accepted, there's no way out of it.

Fair warning: it's pretty depressing.

I second this recommendation. And "The Island" is 100% the Hollywood / Michael Bay version of that story.

Based on a book by the same name. I haven't watched the film but I can recommend the book.
