Campaigners mount last-ditch attempt to save 30 vaquita porpoises left in wild

Mexico's vaquita marina is edging closer to extinction as scientists warned on Wednesday that only 30 were left despite navy efforts to intercept illegal fishing nets killing the world's smallest porpoise.

"The already desperate situation has worsened, despite existing conservation measures and current enforcement efforts," said the report by the International Committee for the Recovery of the Vaquita (CIRVA).

"At the current rate of loss, the vaquita will likely decline to extinction by 2022, unless the current gillnet ban is maintained and effectively enforced."
