Transcript from the Spanish nature program "El escarabajo verde". This episode is called "Pueblos en peligro de extinción," and it deals with the phenomenon of poor, marginal Spanish towns that are losing population and, in some cases, disappearing entirely. The program interviews former residents, activists trying to rescue the towns from oblivion, and economists who discuss the reasons behind the phenomenon.
