Our bodies are engineered to walk within nature. This is oxymoronic from an evolutionary perspective, because Earth is nature, and humans have never been separated from it until very recently, in evolutionary terms. For most of our species’ history, we have been one with nature. I suspect this is why I enjoy hiking so much. The filtered light through the trees, the feel of dirt and mud and rock on my feet, the sound of songbirds and water. It returns my body to what it was designed for. What if the solution, the starting point to solving our global problems, was simply to return to nature more? For on the trail, perspective feels true. Who I am and where I am seems simple and clear: I am a human being walking the Earth.
