Why do humans tend to prefer strict geometric design when nature seems to flow in a chaotic and organic way?

This separation of man from nature made me investigate further. I realized that nature actually does follows certain patterns and that humans sometimes prefer the organic flow rather then the well defined, controlled and organized.

The most significant realization for me was that we are inseparate. Sprung out of the same realm of potential, into life - the never ending play of definition and destruction. Or as I visualize it, a play of geometric shapes and organic chaos.
