A big leap forward in the ambitious campaign to save the world's last unspoiled gray whale nursery at San Ignacio Lagoon in Baja, Mexico.The Mexican government has just announced that 109,000 acres of federal lands surrounding this spectacular whale habitat will be donated for conservation. This fantastic decision may well be the nail in the coffin of a decade-old Mitsubishi plan to build the world's largest industrial saltworks on the shores of the whale sanctuary.
