Discover how science is helping protect the world’s oceans and marine life from environmental threats. The oceans are more than just one of the Earth’s surface features, as over 70% of the Earth is covered by oceans and supports life in more ways than one. They help in the regulating of the weather, oxygen generation and act as a home to innumerable organisms. Nevertheless, the activities performed by humanity to the ocean such as pollution, global warming and overfishing, have put great strains on the ocean’s environment. In the following article we will go over the oceans and the different methods of their preservation, especially of marine biological resources, outlining the goals, means, and some of the tricks used by the scientists and the activists to save the ocean. The aspect of ocean preservation that we are more concerned about is the human reality.
Ecosystem services
In addition, the Ocean and human residence are incredibly interdependent due to many uses of oceans including following Ecosystem services:
Production of Oxygen: It is the Phytoplankton, present in oceans which create more than 50% of the Oxygen of the Earth.
Carbon Sequestration: The Ocean absorbs almost 30% of Carbon dioxide emitted which would otherwise lead to an increase in the global temperature.
Diversity: As per estimation the oceans possess about 230,000 such described species while many millions of other species have not yet been described.
Economic value
The ocean economy has a great value which estimates at about 1.5 trillion US dollars every year. This comprises proceeds from industries such as fishery, traveling and transportation, and shipping. Sustainable governance of these resources is essential for the survival of different communities around the world.
Cultural Importance
The Ocean for several coastal zones is of cultural and capsular significance. It is an integral part of customs, ways of doing things and the peoples themselves. It is important to do so in order to preserve such cultural heritage.
Key Drivers of Ocean Change
1. Pollution
Both ‘land driven’ pollution, including plastic floating around the ocean, and pollution from oil spills are critical to the health of these water bodies. Micron plastic waste is now everywhere – ‘the most remote places in the ocean are now filled with microplastics’.
2. Overfishing
If the present trend is carried on, fishes will be caught quicker than they reproduce leading to breakdown in the ecosystem and a great number that rely on fish for protein will lack enough fish to feed on.
3. Climate Change
Due to global warming, there is an increase in sea temperature, an increase in the level of the ocean, ocean acidification, and these are affecting the marine environment. It is notable that coral reefs which are important for biodiversity are very affected and there are massive bleaches all over the world.
4. Decline Building
Destruction and urban expansion, especially bottom trawling and such, destroy essential habitats such as mangroves, seagrasses and coral reefs and have important fish nursery functions.
Table 1: Key Threats to Oceans
| Threat | Description | Impact on Marine Life |
|---|---|---|
| Pollution | Introduction of harmful substances into oceans | Endangers species, disrupts ecosystems, and harms humans |
| Overfishing | Catching fish faster than they can reproduce | Reduces fish populations and disrupts food webs |
| Climate Change | Rising temperatures and ocean acidification | Affects species distribution and health of coral reefs |
| Habitat Destruction | Damage to critical habitats due to human activities | Loss of biodiversity and reduced ecosystem services |
The Science of Preserving Oceans
Marine protected area (MPA)
A marine protected area (MPA) is an area at sea where human usage is regulated so as to protect marine ecosystems. Research indicates that MPAs can increase biodiversity and brings back fish stocks.
Ecosystem-based management
Ecosystem-Based Management (EBM) is a comprehensive approach that addresses not just a particular species but the whole ecosystem. This approach acknowledges multi-species and multi-environmental involvement which in turn enhances the sustainability of the approach.
Community-based conservation
Community-Based Conservation (CBC) leads the local people to be involved in the successful management of the oceans. This approach recognizes the significance of the local people in the conservation process.
Innovative Technologies
Remote Sensing: Sensing Remote sensing is a technology that has made it possible for people to observe the health of oceans using satellites. Water changes such as sea surface temperature and chlorophyll variations among others can be studied by satellite imaging and these measures can help in predicting and monitoring such changes.
Underwater Robotics: Underwater robotics has also changed the way scientists explore and assess the ocean. These instruments penetrate to bottommost areas of oceans that humans cannot and together with the activity bring back relevant information about the oceans.
Genetic Techniques: Genetic techniques are useful in the assessment of marine populations and historical perspectives of the populations due to changing environments. It is also essential to explore genetic variation for effective management of resources that are under threat.
Table 2: Innovative Technologies in Ocean Conservation
| Technology | Description | Applications in Ocean Conservation |
|---|---|---|
| Remote Sensing | Monitoring ocean health using satellite imagery | Tracking temperature changes, algae blooms |
| Underwater Robotics | Robots that explore and gather data from the ocean depths | Mapping habitats, monitoring marine species |
| Genetic Techniques | Studying genetic diversity within marine populations | Assessing resilience and adaptability |
The Impact of Science on Policy Making and Education
Policy Based on Science
In order to achieve ocean preservation, policies must be formulated and implemented based on scientific knowledge and understanding of managing sustainably. When defining regulations related to fishing quotas, pollution and protection of marine habitats, the lawmakers have to take into account available scientific evidence.
Public Awareness & Education
It is equally important to make the people aware about the need to conserve the oceans so as to create a conservation culture. It is necessary to organize the education of the population concerning the oceans and marine problems, together with schools, NGOs and state bodies.
Public Involvement in Science
Public Involvement in Science includes such methods that require the public to take part in the research projects or monitoring work. These projects allow persons to actively take part in scientific studies and reclamations, thus instilling a sense of care for the biological oceans.
| Project Name | Description | Impact |
|---|---|---|
| Reef Watch | Volunteers monitor coral reef health | Provides data for coral conservation |
| Ocean Conservancy’s Clean-Up | Community beach clean-ups to reduce plastic waste | Reduces pollution and raises awareness |
| Frog Watch USA | Public monitoring of amphibian populations | Contributes to biodiversity data collection |
Studies of the effective management in the oceans – case studies
Coral Triangle Initiative: The Coral Triangle, sited in the Southeast Asia region, is regarded as among the ‘hottest’ marine biodiversity hotspots across the globe. The Coral Triangle Initiative which was launched in 2009 is collaboration of six countries towards the sustainable use of the marine and coastal resources. This initiative has seen to the creation of MpAs and the enhancement of management practices which are more advantageous to the local communities and the marine biodiversity.
The Great Barrier Reef: The Great Barrier Reef, which is the largest fringing reef system in the World, is under serious threat due to global warming and water pollution. Scientists and conservationists are engaging in the restoration of the reef by employing strategies such as the replanting of corals, and curbing nutrient run-offs. Research has shown that the application of such measures can restore the health of the reefs and enhance the diversity of marine life.
The marine stewardship council: The marine stewardship council is an independent charity that governs certification for sustainable seafood. Amnesty Supplement has an MSC program that communicates and encourages these societies to practice accountable engagement. Studies show that fisheries with the MSC certification are more likely to have improved health of the fishes in their waters and the surrounding eco-systems as well.
Conclusion
The science of ocean conservation is critical to the safeguarding of the earth’s most valuable resource. If we know what causes such marine ecosystems’ destruction and how it is possible to prevent this destruction so as to promote the oceans, it is possible for the world’s oceans to be conserved. it is evident that there has to be a combined effort of science, policy, and society for the well-being of marine life and provisions rendered by the oceans
