The Marine Mammal Protection Act Abstract This paper includes information a particular environmental law. Specifically, the Marine Mammal Protection Act is discussed along with the history and background of this particular environmental law. In addition, the reasoning behind its existence will be elaborately deliberated. The Marine Mammal Protection Act The Marine Mammal Protection Act was established and signed in 1972. According to Ray and Potter (2011), this bill was “passed, despite

When you think of mammals, what do you do you think of? You probably think about warm-blooded, air breathing animals. Mammals are animals with spinal columns, which are called vertebrates, that have warm blood, hair, and they breathe air. Yes, all mammals do indeed breathe air; it depends on the size of the mammal for their frequency of breathing. All mammals also provide milk through mammary glands. For example, women get pregnant and they produce breast milk through the mammary glands of their

The Navy Marine Mammal Program (NMMP), located in San Diego, California, has been going on for many years, beginning in the late 1950s, when the Navy began to study the unique attributes of marine mammals, such as their hydrodynamics. By understanding how certain animals maneuver in the water, perhaps the Navy could improve torpedo, ship and submarine designs (Marine Mammal Program). The Navy soon realized that dolphins would be valuable assistants to their divers working in the abyss of the open

Nets in order to reduce Marine Mammal Bycatch A topic that is known for its controversy is the use of acoustic pingers on fishing nets in an attempt to reduce marine mammal bycatch. While this idea seems appealing and has its potential benefits, there are also drawbacks to the use of this kind of device as well. When a device such as the acoustic pinger is invented, it is important to consider the various types of impacts it will have, especially in terms of marine mammal species conservation. The

having on all kinds of organisms, marine mammals came into focus as particularly vulnerable and at risk for adverse health effects with exposure to these contaminants. Since then researchers have worked to determine exactly what harm these animals are succumbing to. The chemical properties of persistent organic pollutants along with the biomagnification of organochlorines through the trophic levels and the bioaccumulation of these chemicals in the blubber of marine mammals, explain why these animals are

Throughout the years, marine mammal bycatch has continued to be a growing concern due to a steady increase in mammal mortality rates. Mike Gaworecki mentions in his article that during this past month the National Oceanic and Atmospheric Administration initiated a rule limiting seafood imports from different countries that do not meet the United States new bycatch standards. Bycatch is a term that means catching unwanted species when intending to fish for a different type of species. On a daily basis

Ecological Roles of Marine Mammals In the recent past, extensive researches have been carried out to determine the role of marine animals in the ecosystem. According to the World Ocean Assessment Team (2017), sea mammals feed at various tropic altitudes, ranging from fresh marine ecosystems to open-ocean ecosystems, and they are also present in almost all latitudes. This paper seeks to examine the ecological roles and significance of the marine creatures in the aquatic ecosystems. Stabilizing the

the world whom specialize in marine mammal toxicology and ecology. These people have devoted their time and efforts towards trying to determine how humanly integrated chemical pollutants are affecting marine mammals. The issue of the impact of chemical pollution on marine mammals has not recently surfaced. This issue has been a big concern to scientists ever since analytical techniques improved and tissue levels of known highly toxic compounds were found in marine mammal species. The source of these

Marine Mammals in Captivity Imagine you are a young orca living out in the ocean, enjoying life, and having a great time. One day you get caught in a huge net, separated from your friends and family, and taken away from your home. You are captured in a concrete tank and forced to perform tricks for money for the rest of your life. Except you are not the one getting paid, but the people that captured you. There are so many anti-slavery organizations in the world today and we are all frightened by
