Healthy marine ecosystems are important for society since they provide services including food security, feed for livestock , raw materials for medicines, building materials from coral rock and sand, and natural defenses against hazards such as coastal erosion and inundation.
Why is marine biodiversity so important?
The importance of marine biodiversity
Marine biodiversity allows nature in our ocean to be productive, resilient and adaptable to environmental changes. Marine biodiversity can prevent one species’ extinction from causing wider negative impacts on a marine ecosystem.
What are the benefits of marine environment?
Marine protected areas help protect important habitats and representative samples of marine life and can assist in restoring the productivity of the oceans and avoid further degradation. They are also sites for scientific study and can generate income through tourism and sustainable fishing.
What are the benefits of greater biodiversity?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
What is marine biodiversity and why is it important?
Marine biodiversity, the variety of life in the ocean and seas, is a critical aspect of all three pillars of sustainable development—economic, social and environmental—supporting the healthy functioning of the planet and providing services that underpin the health, well-being and prosperity of humanity.
What is marine biodiversity?
Marine biodiversity is an aggregation of highly inter-connected ecosystem components or features, encompassing all levels of biological organization from genes, species, populations to ecosystems, with the diversity of each level having structural and functional attributes (Table 1).
What are the top 3 benefits of marine reserves?
Benefits of marine protected areas
- Protection of biodiversity and increased productivity.
- Increased resilience and maintenance of ecosystem services.
- Benchmarking of environmental health.
- Fisheries spill-over.
- Protection of geological features or processes.
- Protection of cultural values.
What benefits do oceans provide?
The air we breathe: The ocean produces over half of the world’s oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth’s surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.
What are the benefits of coast?
Because if you don’t protect coastal ecosystems like oyster reefs, marshes, and seagrass beds, then you can lose a lot of the benefits that we derive from the coast, including productive fisheries, outdoor recreational opportunities, erosion control, storm protection, and water quality.
What are 5 benefits of biodiversity?
A healthy biodiversity offers many natural services
- Protection of water resources.
- Soils formation and protection.
- Nutrient storage and recycling.
- Pollution breakdown and absorption.
- Contribution to climate stability.
- Maintenance of ecosystems.
- Recovery from unpredictable events.
What are the 4 benefits of biodiversity?
The four key benefits are: (1) Biodiversity Provides the Natural Resource, (2) Biodiversity Provides the Genetic Resource, (3) Biodiversity Maintains a Stable Ecosystem, and (4) Biodiversity Ensures Optimum Utilization and Conservation of Abiotic Resources in an Ecosystem.
What is biodiversity and its benefits?
Biodiversity underpins all ecosystems and their services
Biodiversity. Diversity can be defined as the number of different items and their relative frequencies. … Biodiversity is fundamental for the provision of ecosystem services, which we depend on for food, air, and water security, and multiple other natural benefits.
