Marine mammal rehabilitation programs have been underway and regulated in the United States for more than 40 years. In 1973, injured and distressed manatees were rescued or aided in Florida. Eventually, the program was formalized into the Manatee Rescue, Rehabilitation, and Release Program managed by the US Fish and Wildlife Service.
Harpoons enabled the Inuit to hunt large marine mammals from a distance in the umiak and kayak in the open Arctic Ocean. Hominy – this is a specialized corn dish known by many North American native people. Today, it is most commonly seen in the Southern United States.

Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans ( whales , dolphins and porpoises ), pinnipeds ( seals , sea lions and walruses ), sirenians ( manatees and dugongs ), sea otters and polar bears .
Erich Hoyt's work is "very much at the forefront of work on marine protected areas," [34] [driving] the shift from taxon-oriented protectionism (e.g., the Marine Mammal Protection Act) to more ecosystem-oriented approaches to conservation [and] marking...the growing relative importance of marine conservation vs. terrestrial conservation."

Their mission statement for their 14th goal, Life below water, is to "conserve and sustainably use the oceans, seas and marine resources for sustainable development". [13] The United Nations has also declared 2021–2030 the UN Decade on Ecosystem Restoration, but restoration of coastal ecosystems is not receiving appropriate attention. [14]
Marine life can be roughly grouped into autotrophs and heterotrophs according to their roles within the food web: the former include photosynthetic and the much rarer chemosynthetic organisms (chemoautotrophs) that can convert inorganic molecules into organic compounds using energy from sunlight or exothermic oxidation, such as cyanobacteria ...
Marine conservation, also known as ocean conservation, is the protection and preservation of ecosystems in oceans and seas through planned management in order to prevent the over-exploitation of these marine resources. Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is driven by ...
