Marine Mammals Need Distance?
Does mankind have a positive effect on marine mammals as a whole? As usual, the direct answer is non. Specifically, mankind continues to have a negative effect on marine mammals such as sea otters, and whales. Mankind's negative effect on marine mammals traces back to the time mankind learns to efficiently kill whales in the 1800's since mankind learns to effectively hunt whales; additionally, in the 1900's mankind begins to hunt sea otters in California. Thankfully, as Tom Garrison states, a science professor, "In 1994, the International Whaling Commission voted overwhelmingly to ban whaling in about 21 million square kilometers around Antarctica, thus protecting most of the large whales."

Specifically, the discovery of large quantity oil in whales, such as the gray whale and right whale, susceptibly causes humans to hunt them in the 1800's until the International Whaling Commission bans the hunt for the majority of whales. However, pirates still hunt whales illegally, thus whales will be in danger regardless of laws that prohibit whaling. Additionally, besides the endangering of whales due to humans hunting them, whale populations continue to decline thanks to pollutants that humans release out into the ocean, which causes them to not be able to reproduce. For example, as Dr. Ross notes, a member of the Institute Of Ocean Sciences, polychlorinated biphenyls (PCBs) "PCB’s have been associated with toxic effects in marine mammals such as endocrine disruption, which can cause impairment of reproduction."( Wildwhales.org). Besides whales, humans have caused sea otters to decline in population since they have the densest coat out of all the mammals in the world. In fact, sea otters have 1 million individual hairs per square inch and have 3 layers of fur. Additionally, another human activity which is net fishing causes sea otters to die, because marine mammals need to go up to the surface to breath. However, arguably the most devastating impact towards both sea otters and whales that result from human activities is oil spills. Indeed, as defender.org states, a website informing on how to protect sea otters, "When sea otters come into contact with oil, it causes their fur to mat, which prevents it from insulating their bodies."(defenders.org), and leads sea otters to be unable to be warm, causing the to die from hypothermia. By contrast, oil spills cause food not to be abundant causing whales to stress beach themselves on accident while searching for food. To top the negative effect humans have on marine mammals they try to keep them in captivity
Specifically, humans keep marine mammals
