People who spend much of their time inside either working or watching tv become disconnected from the natural world. This causes a kind of apathy toward the importance the natural world has both on our physical well being and our spiritual well being. Also if people do not experience things, they become afraid of it. Oooh dirt, oooh bugs, oooh germs and the creatures in nature which are vitally important in the balance of our natural world become disposable. "Out of sight, out of mind" and we all suffer from that mentality.
