The oceans are extremely vast and filled with incredible and mysterious creatures. Unfortunately, many of these creatures are endangered or are threatened because of pollution and overfishing. The pollution has become such a problem in our oceans that there is an area, in the ocean, known as "The Great Pacific Garbage Patch." It is about the size of Texas! Not only are sea turtles trying to much of the jellyfish-like trash bags, but other animals are beginning to digest and become tangled in this mess of garbage.
Overfishing has also become a large part of the endangerment of sea creatures. In Asia, several sea creatures are being caught and killed for commercial use. Tuna, sharks, sea horses, and many others that are being placed on the endangered list of animals.
If these amazing creatures were to become extinct, then the balance of the ocean would become chaotic. In order for other species to be balanced, the other species (that eat other species) must remain alive. It has always been this way and should remain this way.
