Coastal Marine Ecosystems and Their Importance

Front

Coastal marine ecosystems are vital environments where living organisms interact with nonliving surroundings.

Back

These ecosystems include coral reefs, mangroves, seagrass beds, and estuaries, essential for the planet's health and provide numerous benefits to humans.

Front

Ecosystems are dynamic communities of plants, animals, microorganisms, and their nonliving environment.

Back

They interact as a functional unit, producing services that benefit human populations, such as food and building materials.

Front

The Millennium Ecosystem Assessment (MEA) categorizes ecosystem services into four types.

Back

The four types are provisioning, supporting, regulating, and cultural services.

Front

Provisioning services in marine ecosystems include fisheries and building materials.

Back

These services provide essential resources for human populations.

Front

Supporting services in marine ecosystems encompass nutrient cycling and life-cycle maintenance.

Back

These services are crucial for various species' survival and ecosystem health.

Front

Regulating services in marine ecosystems include carbon sequestration and erosion prevention.

Back

These services help maintain ecological balance and protect coastlines.

Front

Cultural services in marine ecosystems offer tourism, recreation, and aesthetic benefits.

Back

These services contribute to the economic importance of marine and coastal ecosystems.

Front

Coastal marine ecosystems face threats from unsustainable practices, climate change, and pollution.

Back

These threats lead to rapid degradation and disruption of ecological processes.

Front

Ecosystem-Based Management (EBM) is a holistic approach gaining recognition.

Back

EBM focuses on protecting entire ecosystems, considering physical, biological, economic, and social interactions.

Front

EBM aims to ensure the resilience and sustainability of coastal and marine ecosystems.

Back

It addresses the challenges of climate change and optimizes benefits among diverse societal goals.
