One of the key elements of Pagan thought is connecting with the Earth, Nature, and/or the land. As a general thing, Wiccans seem to focus more on Nature, Druids seem to focus more on the Earth, and Heathens seem to focus more on the land. however, there are always individual exceptions to these generalities. I have always felt very attached to the land around me, especially hills and ranges of hills.
The Pagan revival began, in part, because people felt alienated from Nature by the Industrial Revolution and living in cities.
Looking at other indigenous spiritualities and religions around the world, we can see that connection to the land and Nature is extremely important to them. This connection includes awareness of ecosystems, bio-regions, animals, plants, seasonal changes, rivers, rocks, and trees.
