  Funny how you get used to a word so much you stop thinking about what it means.
  We have three capitals: financial, social and natural; and  our objective is social and environmental growth. Like this:
  
  

investing in our soil: constantly adding organic matter, increasing microorganisms, improving structure, going LARGE on compost....black gold!

investing in our habitat: planting bee friendly plants, trees and flowers and massively increasing biodiversity from a bracken and bramble tangle of low biodiversity value
