Ships must slow down more often to save whales, feds say

Vessels off the East Coast must slow down more often to help save a vanishing species of whale from extinction, the federal government said Friday.

The National Oceanic and Atmospheric Administration made the announcement via new proposed rules designed to prevent ships colliding with North Atlantic right whales.

Vessel strikes and entanglement in fishing gear are the two biggest threats to the giant animals, which number less than 340 and are falling in population.
