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.

Trawling effects on marine biodiversity

Trawling effects on marine biodiversity

Trawling is an approach in fishing that involves pulling fishing nets through nets behind at least one boat. In trawling, a special net used for fishing is known as a trawl. It is same as online courses to help you prepare for the GRE testduring exams time.

Trawling is different from trolling. Students often in the exam preparation process confuse the two terms. The difference between the two methods is while trolling is for recreational and commercial fishing, trawling is mainly done for commercial purposes. Besides, trawling is used as a scientific sampling method.

The fishing boats used for trawling are called trawlers or daggers. They vary in size from small to large depending on the user’s preferences.

Trawling is divided into two:-

Bottom trawling

This refers to towing trawl close or along to the sea bed.

Bottom trawling

Midwater trawling

Refers to towing the trawl through free water just above the sea bed.

Midwater trawling

Pros of trawling

Provides human food such as fish for consumption

Creation of employment opportunities

Cons of trawling

It causes overfishing hence extinction of a particular fish species. Species that can be extinct include, eel, Atlantic code, sea bass, sturgeon, etc

Kills seabed microorganisms as a result of heavy fishing machinery moving across the seabed.

Trawling is a fishing method that adversely affects the environment. Trawling is a fishing method that is discouraged due to the lack of selectivity; also, it causes a lot of damage to the seabed.

Selectivity effect

Trawling is a method of fishing kicked off in the 15th century. Trawls used in fishing are non-selective. They sweep all the fish of all sizes. Both the desired and undesired in the market.

Some fish species end up being killed accidentally as the trawls sweep across the sea bed.

Trawls also catch unwanted fish species like sea turtles, sharks, dolphins.

In trawling, size selectivity will be controlled by cod-end’s mesh size. The cod end is the part of the fish where the fish are stored when they enter the trawl nets. Some fishermen make them smaller and therefore catch very small fishes hence extinction of a particular species of fish in the sea.

To reduce the catch of unwanted size of fish species, grinds of nets should be fitted to the parts of the trawl to allow a given size of fish to escape while retaining the rest.

Damaging of environment

Trawling has been so controversial because it causes a lot of damage to the sea environment. Bottom trawling involves the act of towing heavy fishing gear above the seafloor. This large sea gear causes environmental destruction in the ocean such as coral shattering and damage of fish habitats. The weeds, which are used as fish food, are also destroyed.

The impact caused by these heavy fishing gears reduces the species diversity and further causes ecological changes in the fishing area.

Trawling directly kills various fish species around the world. For instance, this method of fishing kills coral reefs by breaking them and burying them in sediments. Besides, it kills coral reefs by wounding coral tissues hence being exposed to infections

The sea ecosystem plays a concrete role in the global functioning of the planet. The functions largely depend on deep-sea diversity. Trawling along the seas has major impacts on sea biodiversity and it causes their degradation. It causes the collapse of benthic biodiversity and ecosystem functions. There is a need for immediate actions to sustain fisheries in the deep sea from destruction.

What to Wear When Scuba Diving

What to Wear When Scuba Diving

Scuba diving is an enjoyable activity that only a few would even dare. If you are a scuba driver, you might have discovered that your fellow divers usually wear clothing under the custom t shirts or wetsuit.

These undergarments are important because they help uphold body temperature and safeguard you from the harsh conditions of the sun and many other hazards. Sometimes, the deeper waters are colder than the upper waters, so when you dive, the undergarment will protect your body from the cold temperature. In case you’re wondering what to wear beneath the standard wetsuit, here are a few we can suggest.

Diving Shorts

Fitting shorts are ideal for both men and women when worn beneath the wetsuit. It serves as an additional layer for protecting the body skin from colder temperatures. Also, you can wear and remove your wet suit easily.

To get a suitable diving short, make sure the materials are soft and comfortable. The neoprene fabric is ideal as it is light and thick, thereby providing you with more warmth.  Furthermore, it is easily stretchable and doesn’t shrink when you wear a wet suit. The shorts are generally unisex, so you don’t have to go out searching for a different brand for your partner.

One-Piece bikini

Bikinis or one-piece swimming costumes are an excellent undergarment for women. They cling onto the body perfectly that they don’t move whenever you pull over the wetsuit. Usually, athletic swimming suits for women are the most suitable.

If you opt for a string bikini, remember to tie the string bikini ends on the side. It will stop them from squeezing the wetsuit’s zipper. This way, you’ll be more comfortable.


The speedo is suitable for male drivers as it doesn’t shift when getting in the wetsuit. The fabric is thin and tight, making it great for diving. If you are the type who feels a little bit embarrassed when you wear a skimpy swimsuit, you can wear a pair of shorts before it’s time to put in the wet suit.

Vest/Compression Shirts

These are great for female divers who don’t prefer a one-piece bikini. Apart from diving, you can wear them during swimming, water sports, and even when sunbathing. Just make sure you go for a vest made of light and thin fabric. For male divers, a compression shirt is excellent as it provides more warmth to the upper body. Depending on your liking, you can even opt for one with a full sleeve.

Go Commando

If you are a type of person who doesn’t care too much, you can choose to wear nothing beneath the wetsuit. However, be prepared to encounter some challenges when out of the sea such as the lack of a private place to change.


Looking at the suggestions above, you will realize that there are different clothing options you can wear under your wetsuit depending on your preference. You can opt for a diving short, one-piece swimsuit, speedos, compression shirts or vest, or even nothing.

Whichever you choose, always make sure that the materials are comfortable even if they are custom T-shirts. Make sure they’re comfortable and fit you correctly.

Urban Wildlands

Urban Wildlands

Coastal communities, especially densely populated ones, can also be considered as urban coastal communities. Some species can adapt and be domesticated to co-exist with humans. In some occasions, human settlements tend to introduce invasive species, especially around mowed grasslands, which in turn could affect the proximate coastal marine ecosystem, thereby affecting the marine biodiversity.

Thus, urban “wildlands” should also focus on sustainable land development, especially in the fringes of urban settlements were wildlands are present.

In these mentioned places, some species could be endangered and threatened either through a combination of habitat destruction, relentless hunting, and/or the introduction of invasive species that disrupt the local ecosystem.

The center is open to individuals who have a passion to support our expertise in land use, ecological balance, water, and soil standards, and biology which in turn translates to projects that will preserve habitats, suppress polluting industries, promote efficient use of resources, and other similar endeavors.

This is in line with our mantra: that biodiversity is a delicate balance of ecosystems. Partnering with urban planners and developers is also part of the strategy to support the continued protection of marine biodiversity.

Public Lands Work

Public Lands Work

In the United States, almost half of its land area is owned by the American public and managed on their behalf by government agencies. A good number of water bodies pass through these public lands, hence any pollution or environmentally-destructive activities done along these water bodies can potentially affect marine life as well. With the growth of the CBD industry in Canada, land has been put aside for growing cannabis. This is especially in the case for pure cbd oil. Many local golf courses have provided help to the cause. Low to mid-range players try to allow the scientist room to explore using rangefinders and other tools.

Due to that, the Centre for Marine Biodiversity also uses a wide variety of its resources at its disposal in order to ensure that public lands are helpful in preserving the rich biological diversity present in the marine environment.

Ocean ecosystems are interconnected with terrestrial ecosystems, which is why well-maintained public lands are also essential in preserving marine biodiversity.

Aside from that, worldwide climate change is usually caused by terrestrial activities. In order to fulfill the core mantra of the center, public lands are also part of its concern as most methods to fight climate change such as carbon capture and sequestration, natural via trees or artificial, are done usually in public lands.

In its end, the center advocates the use of sound science, just laws, green policies, and strategic collaboration to protect and restore ecosystems that would be of critical use to marine biodiversity.

The center believes that efficient use of public lands will be of help in order to protect current niches of different species. While not directly a priority, the center advocates for sustainable land use that would not harm species and ecosystems – from use of organic fertilizers to opposing unsustainable logging. This is done through legal ways such as lawsuits, policies, and lobbying to usher sustainable use of public lands that would in return ensure the survival of many species both terrestrial and aquatic.

We work toward a future in which both marine and terrestrial ecosystems continue to work in sync to ensure the survival of its constituents.

Population and Sustainability Work

Population and Sustainability Work

Rapid human population growth is a factor that aggravates overconsumption, economic inequality, and pollution. It is one of the major causes of critical environmental problems like wanton habitat destruction, overfishing, and climate change. While humans are not always the enemy, the centre promotes population control in order to curb runaway human population growth. Fishing from the regulated areas using the correct fishing chairs is one step in the right direction. Futhermore, employing fishing motors for trolling can make a huge difference to the environment.

These include pressuring governments to empower reproductive health of women, universal access to health care and sex education, and paradigm shifts in order to promote the idea that population growth in some areas is a factor in their continued status as an underdeveloped country.


  • Promoted reproductive health among various partner communities
  • Helped support groups who also promote accessibility to reproductive health to critical communities
  • Introduced the concept of sustainable growth to coastal communities which include the need to protect women’s reproductive rights

International Work

International Work

Protecting marine biodiversity is a global task. Ocean ecosystems are interconnected, and thus no country has a “monopoly” of responsibility when it comes to protecting these species. The center is committed to protecting marine species located in the world’s vast oceans. All kinds of species; even those that are even very much distinct from each other such as the Okinawa dugong, the polar bear, and the hawksbill turtles are covered by the scope of the center’s hard work.

We take pride in involving ourselves to take action and utilize standing international biodiversity protection treaties and trade laws to ensure the survival of many species. With our satellite offices in North America and our grassroots conservation-group allies in Europe, Africa, and Asia, the center is committed to securing a future for innumerable species and their respective habitats worldwide.

Here’s how we do it:

  • Establish connections with partner government agencies, universities, think tanks, advocacy groups, and related organizations to ensure smooth coordination for biodiversity-related projects
  • With the help of our established network of allies and supporters, the center can present petitions and legal action under relevant local and international laws depending on the situation the center is facing
  • Thanks to its established network, the center can advocate for international policies that would ultimately protect biodiversity, including marine biodiversity
  • Our allies can also build coalitions and partnership in relevant undertakings or projects
  • As part of the advocacy building, the center and its allies can utilize mass media for its undertaking and projects related to protecting biodiversity

Oceans Work

Oceans Work

The oceans around the world are so vast that they cover about 362 million square kilometers, which is around 70.9% of the Earth’s surface. Therefore, the scope of protecting marine biodiversity is a gargantuan task – almost as if one is literally carrying the earth in their shoulders.

A lot of problems may occur, especially at areas near human settlements – including overfishing, coral reef destruction, oil drilling, mangrove forest decimation, climate change, and acidification of oceans – which can threaten marine biodiversity.

The center tackles this problem as part of its international work and advocacy. We believe that the oceans, being vast, contain havens of yet to be discovered marine species. Hence, it is important to protect the biodiversity of these vast oceans from various threats.

One critical example of marine pollution is plastic pollution. These include even the tiniest microplastics and even large plastic-based fishing nets intentionally and unintentionally released by human activities. These plastic wastes can severely injure marine life such as sea turtles, seabirds, and whales by interfering with their normal digestion and feeding patterns.

To make matters worse, climate change is one of the reasons why the oceans are getting warmer and acidic, which in turns makes it harder for species to adapt. Coral bleaching, caused by ocean acidification, is also bad for marine biodiversity.

To respond to that dilemma, we take these measures:

  • Utilize sound science coupled with the latest data in order to prepare projects that would have the highest impact for the protection of marine biodiversity
  • With the help of our established network of allies and supporters, present petitions and legal action under relevant local and international laws that could counter ocean-destructive practices
  • With our established network, advocate for more protected habitats for marine species
  • Build coalitions and partnership in order to promote sustainable fishing
  • Utilize mass media to promote the protection of ocean biodiversity

Environmental Health Work

Environmental Health Work

The Centre for Marine Biodiversity wants to ensure the safety of marine biodiversity from an array of usually anthropogenic toxic substances. We believe that every product of human industrialization has effects on the health of not only humans but also other species.

The Industrial Revolution of the 18th century introduced countless novel products which in turn caused the release of numerous kinds of pollutants into the environment. While industrialization was not necessarily an evil development, it is careless and unsustainable industrialization that is the bane of modern civilization.

Such careless and unsustainable industrialization is usually driven by the greed of the few, allowing a lot to suffer needlessly. Pollutants, ranging from poisonous organic chemicals to heavy metals, affect the vulnerable population. This toxicity endangers the health of vulnerable populations such as the urban poor.

The pervasiveness of these chemicals means that they persist in the environment, affecting generations of people and non-human species. Sound research has found a wide variety of chemicals, many of which are toxic, in the blood of newborn human babies.

In response to that, we follow these methods:

  • Utilize sound science coupled with the latest data in order to prepare projects that would best shield the environment from the impact of these toxic chemicals
  • With the help of our established network of allies and supporters, present petitions and legal action under relevant local and international laws that could counter polluting practices to promote good environmental health
  • Advocate for more protected habitats for marine species
  • Utilize mass media to promote the good use of natural resources
