Less then 400 right whales are left on earth today and the US has taken action to try and save the species. Today a new law takes effect that forces freighters to slow down when traveling through migration paths in the North Atlantic.

The right whale was driven almost to extinction in the 1700's by capitalists seeking whale oil. In recent years they were threatened more by the enormous ships that crisscross their migratory path.
Studies have shown that deceasing the speed over these areas could reduce right whale deaths by 80%.

Once endangered, scientists say that this new law may mean the survival of the species.
