"Why does 'nature' use fractal process for creation?"

Simple; once you have a pattern created, reuse it, on varying scales, and in varying positions. Why waste something that works? That is the essence of a fractal's nature: self-similarity and repition of it's parts.

However, I don't believe that "Fractal Mathematics" was "born to describe things in nature..." as Fractographia said. The 'fractal nature' of nature is a hindsight issue. It began as a pure numbers experiment by Mandelbrot, Julia, and others. The art portion arrived when those mathematically derived numbers were plotted in a visual graph of the results, and it was realized then that the results were visually pleasing, and similar to what could be seen in nature. We just didn't have the proper math to describe all of nature's complexity until after fractal math was invented. Thus, the 'art' of fractals is a secondary result of the mathematics.
