Journalist Ashley Pierce observed that, in the wild, male orcas live to an average of sixty-five years while females live an average of ninety years. The natural environment creates more than double the lifespan faced in captivity (Pierce 1). Orcas live a shortened lifespan in captivity because the whales can not handle the lack of space given. Over a period of the orcas’ life in confinement, results in the bodies shutting down more and more every day. The Beacham 's Guide to the Endangered Species of North America, expresses that, orcas venture throughout the Pacific Ocean within the whales lifespan (Killer Whale 1).
Lars Gustafson 11/4/15 GEOG 304 Research Paper: Shark Finning With an alarming one in four shark species endangered across the globe, we have come to a breaking point where our oceans ecosystems could suffer permanent damage if the practice of shark finning in the oceans off of Eastern Asia continues as shark population’s plummet. According to www.stopsharkfinning.net, tens of millions of sharks are killed every single year just for the fins that are the main ingredient in shark fin soup. Shark fins are harvested to feed the growing demand for shark fin soup that is an Asian delicacy food. When the sharks are finned they are usually thrown back into the water and left to drown slowly.

The endangered pupfish, though rare, also rely on the basin for survival (10). Pupfish are also the only native species in the Salton Sea, thriving in shallow bodies of water with a high salt and heat
