the nature of things

So we step away from nature for the sake of civilizing ourselves, thereby creating a void that we try to fill up with stuff, activities,entertainment, whatever, it doesn' really matter what we chose to fill it with, the fact that civilization as we practice it leaves us with a burning hole to fill is the point I'm trying to make. There are numerous case studies of indigenous peoples. These studies show that they do not experience such a void. In fact there are diseases found in civilized cultures that are not found in the natural environment, such as schizophrenia , bi-polarism. Einsteins theory of relativity, we've made monumental strides towards physical health issues but we're loosing our minds in the process. I just don't think we can change the nature of things.
