It is interesting to note that many of the countries that do well are composed of small islands (including the Dominican Republic, Jamaica, Cuba and the Philippines). Half of the ten small island nations included in the latest global HPI are in the top 20 per cent of the HPI rankings. Only one of the remaining five is not in the top-half of the rankings. The remarkable survival and relative success of other islands suggests that more immediate contact with, and hence a greater awareness of, physical limits can successfully encourage ecological efficiency.
