premise: Blue-and-white agapanthus cling to the top of the promontory, and pine and eucalyptus creep right to the edge, but an even greater degree of daring can be seen hundreds of feet below, where farmers have managed to salvage tiny plots of arable land, terracing them into little green postage stamps stuck onto the sides and base of the cliff.
hypothesis: The farmers on these tiny plots are making very small profits for their efforts.
