Vital Role of Marine Biodiversity

Vital Role of Marine Biodiversity

The marine life has dramatically decreased since industrialization started in the 19th century. According to, The destruction of marine habitats is mainly caused by climate change, pollution, and trawler fishing. Amid the uncontrollable distraction, there’s only a limited recorded and identified deep sea as well as polar oceans species. Hence the marine species are far more difficult to discover than that on the land.

How important is biodiversity?

All species are a part of the ecosystem. Every one of them plays a specific role needed by the environment to thrive for animals’ survival and, most importantly, humans. Each marine and land species alike work by:

Capturing and storing energy;

decomposing organic material;

producing organic material;

helps in the regulation of climate;

controlling pests or erosion;

and helps regulate atmospheric gases.

Economically the marine biodiversity is a great source of food, namely livestock, agriculture, seafood and fish, and biomedical research. The coral reefs provide a home to thousands of varieties of species that could be discovered or developed into medicines. This thenceforward is used to maintain human and animal health alike. It could also be processed for Industry – cosmetics, textiles, recreation, and tourism- beaches, ecotourism, etc.

How does biological diversity work?

All of the species have a customized physical and biological needs. There are living things that can thrive without the need to deprive the needs of their fellow species. For instance, some of the algal species require sunlight to grow and form a tree-like crown. While the other algal types prefer to stay in the shadow beneath the latter algal specie for its nature, only require minimal sunlight. The two can perfectly survive together without depriving the needs of one another. These two produce more food resources for other species than single specie who need to thrive alone. This positive characteristic of marine biological diversity is called the “complementary effect.”

On the other hand, the “particular ecosystem” is the contraposition of the complementary effect. These are the efficient species that are required to survive alone. For example, the gastropods and isopods are two invertebrates wherein each has different food preferences. The gastropods graze on the thin layers of microalgae using their sturdy rasp-like tongue, while isopods opt for larger filamentous algae types. The seagrass then is grazed by the gastropods when the algae flora on the seagrass’s blades was occupied by thin growths of microalgae. In some cases, when the water has a higher nutrient content, the fibrous algal species predominate. As a result, it allows the isopods function to keep the seagrass free from algae.

These two species, however, performs depending on the environmental conditions. To wrap it up, the selection effect is performed only by single species.

The ocean is a plethora of types in which some have the same species but has differences in terms of genetic makeup.

How are the marine biodiversity under threat?

The instant changes in water temperature, nutrient concentrations, and salinity were bought by habitat destruction, overfishing, pollution, and the introduction of new species, resulting in a dramatic decline in the ocean’s diversity. Species, identified or not yet discovered, are continuously disappearing because of this. Coral reefs are commonly known to bestow a great biological diversity and are being disturbed and transformed by overfishing. The scarcity of reef fishes keeps the coral free of the algal overgrowth living the coral larvae struggle to establish themselves.


The globe was made of 71 percent water; likewise, the marine species or organisms cater to humanity’s economic, cultural, scientific, environmental, and ecological needs. Removing or destroying their habitat makes all these provisions fade. Therefore, the more we take care of this diversity of ecosystems to flourish, the greater the balance will be maintained, and the productivity will increase.

Being aware of marine biodiversity’s vital role is the first step to taking care of these ocean lives. Thus, prioritizing this as subjects for classes is essential, either via online tutoring or offline at school, just to make the future generations understand and comply.
