ANIMALES EN PELIGRO DE EXTINCIÓN
Mcgavin G.
Cinco grandes extinciones se han producido, por lo menos, en la historia de la Tierra, en las que al menos el 95% de las especies desaparecieron. Las causas han sido atribuidas a masivas erupciones volcánicas, al potente impacto de algún meteorito y a los cambios climáticos. Este libo examina la sexta gran extinción atribuible a la actuación del ser humano.
