"Although commercial whaling of the species is now banned, the population is now so small that any further mortalities may severely impact on the survival of the species." (source 9) This is explaining that if another severe harm came to blue whales they could become extinct. The blue whales may no longer be commercial fished, but there are other factors that can significantly reduce the amount of blue whales in the ocean. "Blue whales have few predators but are known to fall victim to attacks by sharks and killer whales, and many are injured or die each year from impacts with large ships."
