  • we are running up an ecological debt of $4tr (£2.5tr) to $4.5tr every year
  • populations and consumption keep growing faster than technology finds new ways of expanding what can be produced from the natural world

  • The global average consumption was 2.7 hectares a person, compared with a notional sustainable capacity of 2.1 hectares.

  • The study calculates that the Mau Forest's value to the electricity sector is $131.6m.
  • This blaze of lurid colour helps to make tourism one of Kenya's biggest earners, and the study reckons this industry receives $65 million in benefits from the forest.
  • Further services provided by the forest include an estimated $89million in storing carbon, $98million in controlling soil erosion and $21million in support for fisheries.
