Bandas, enjambres y devastación: Las plagas de langosta a by Xavier Sistach

By Xavier Sistach

Las plagas de langosta han amenazado al hombre desde el neolítico, momento en que éste aprendió los rudimentos de l. a. agricultura y fijó su residencia en un lugar permanente, sedentarizándose. Un enjambre de langostas migradoras puede albergar miles de millones de individuos que no respetan el equilibrio de los angeles naturaleza y destruyen a su paso los angeles masa vegetal existente, rompiendo por completo los angeles cadena trófica y exponiendo a los seres vivos que de ella dependen a una muerte segura por inanición. El hombre ha sido testigo, siglo tras siglo, de estas enormes catástrofes que aparecen y desaparecen de forma súbita. Las ha intentado explicar y las ha combatido con escaso éxito. Entre los años 2003 y 2005 tuvo lugar en África los angeles última gran plaga de langostas. Pero no será los angeles última.
