As climate change and the rise of the sea-level become more prominent, humankind has been dealing with a series of water-related problems requiring creative solutions. Island nations like Tuvalu and Kiribati have already undergone geographical changes due to sea-level rise, even as residents of low-lying outer islands within Kiribati’s national boundary retreat inward. One proposed solution is “Seasteading,” a promising alternative to traditional, terrestrial governance to vulnerable island nations like French …

Earth is rightfully called the Ocean Planet – more than 70 percent of the surface is covered by sea. Despite being such an essential part of life, more than 80 percent of the world’s oceans are unmapped. According to the American Museum of Natural History in New York, merely 10 to 15 percent of the seafloor has been mapped with accuracy, which means we know less about the seafloor than the surface of Mars.
However, technologies of sea exploration…
Seaweed is a type of macro-algae generally live on the bottom of shallow waters that are exposed to sunlight. It is a lower level plant belonging to the thallophytic division. The classification of seaweed is divided into 4 classes based on its pigment content, namely green seaweed (Chlorophyta), red seaweed (Rhodophyta), brown seaweed (Phaeophyta) and blonde seaweed (Chrysophyta). All parts of the seaweed body are called the thallus. There are various forms of…

Ecosystem services are something from ecosystems that are beneficial to humans (Costanza, et al., 1998). An ecosystem service contributes various interrelated ecosystem structures and functions. Well-functioning ecosystems and proper natural resources are the basis for constant ecosystem services to humans. Ecosystem services found in coastal areas include mangroves, coral reefs, seagrass meadows and small islands. These ecosystems are interrelated…

The seafood industry remains booming. It comprises 16% of the protein we eat globally, the majority of which is farmed. Aquaculture is surpassing global beef production, and by 2030, it is predicted that over 60% of the world’s seafood will be farmed. However, most of our seafood resources are depleting, as there have been many reported cases of overfishing, resulting in decreased wild-caught seafood production. As a way to curb this problem, open ocean aquaculture…

As the global population is expected to reach 9 billion by 2050, demand for food and feed will substantially increase, and meeting the demand of the world’s growing population is becoming a major challenge. Inland aquaculture may be a better alternative but it could involve clearing more rainforest and draining more aquifers or using more fertilizers and pesticides as agriculture spreads to marginal lands. For these reasons, offshore mariculture offers significant potential…

Marine debris or litters can be defined as all persistent, manufactured, or processed solid materials disposed of or abandoned over coastal and marine environments. Within marine debris, plastics constitute the dominant pollutant item. Its distribution ranges from the world’s most remote beaches, floating in the middle of the ocean, the deep seabed, and inside aquatic animals, to frozen within the polar ice. The detrimental impacts of plastics are largely associated with its high…

People have been living on islands for decades. It may be from the busiest, well-developed island to the most isolated one. People are drawn to reside on an island due to its beauty and rich marine biodiversity. As more resorts and tourism spots were developed, there has been a significant spike of inhabited island. Human expansion on an island is often followed by a large number of wastes, which may include solid based litter such as marine debris or wastewater. Wastewater …
