"Life exists to modify carbon"?

I read an article several years ago in which the following argument was made: "life" exists to modify carbon. The assertion was that "life" arose as the most efficient method for creating certain forms of carbon utilizing all available resources, including sunlight, etc. Does anyone know of the article or of the broader theory?
