Whales and Dolphins in Danger

In 2007, a film called “The Cove” was released revealing the savage hunt of dolphins in Taiji, Japan. In 2013, “Blackfish” was released, revealing the monstrosities of keeping killer whales captive at SeaWorld. Both films received award nominations and massive media attention for their call to action and revelation of the endangerments of marine mammals. However, there are so many more dangers to whales and dolphins than just dolphin slaughter, or circus shows at SeaWorld. This paper will cover the threats to these marine mammals, and why the world should care about their endangerment.

Whales serve as nutrient recyclers; they act as both predators to a wide range of fish, but can also be prey to other killer whales. After their death, even, they provide nutrients for other organisms. Whales store a lot of carbon in their bodies so in death they serve as both food and as a home to other creatures.
