At its core, what is work? Isn't it the use of energy to rearrange things into a more useful form? What do you do at work all day? No matter whether your rearranging digital data, physical objects, or music notes, most jobs can be summed up that same way, right? But what is the origin of the energy we use to do our jobs? Unless your using nuclear power it all comes/came from the sun!
Natural systems use energy from the sun to rearrange things in the environment into more useful forms. Why not tap into that energy, and let it work for us instead of just fighting (mowing?) it? It IS possible to rearrange the places we live so that the energy of the sun is working for us, rather than making work for us.
The job of the Permaculture Designer is to understand how energy flows through where you live, and then to layout an efficient system, where (preferably) the needs of everything in the system are met by something else in the system. Again, small steps are ok, but its so much fun enjoying your environment, rather than fighting it, the steps come easily.
