S1: Importance of Marine Habitats

Biodiversity Hotspots
Marine habitats, such as coral reefs, mangroves, seagrasses, and deep-sea ecosystems, are critical biodiversity hotspots. These environments support a vast array of marine life, including fish, invertebrates, marine mammals, and seabirds. Coral reefs, for example, are home to approximately 25% of all marine species, despite covering less than 1% of the ocean floor. The complex structures of these habitats provide shelter, breeding grounds, and feeding areas, facilitating high biodiversity and complex ecological interactions.

Ecosystem Services
Marine habitats offer a range of vital ecosystem services that are crucial for human well-being and the health of the planet.

Carbon Sequestration: Mangroves, seagrasses, and salt marshes are particularly effective at capturing and storing carbon, helping to mitigate climate change.

Coastal Protection: Coral reefs and mangroves act as natural barriers, protecting coastal communities from storm surges, erosion, and flooding.

Fisheries Support: Many marine habitats serve as nurseries for juvenile fish and invertebrates, supporting commercial and subsistence fisheries. Healthy habitats ensure the sustainability of fish stocks, which are vital for global food security.

Tourism and Recreation: Healthy marine ecosystems attract tourists, supporting local economies through activities such as diving, snorkelling, and recreational fishing.

Threats to Marine Habitats
Despite their importance, marine habitats face numerous threats that jeopardise their health and functionality.

Climate Change: Rising sea temperatures, ocean acidification, and sea-level rise pose significant risks to marine habitats. Coral bleaching, driven by increased water temperatures, has caused widespread damage to coral reefs worldwide.

Pollution: Marine pollution from land-based sources, including plastic waste, agricultural runoff, and chemical contaminants, degrades habitat quality and harms marine life. Oil spills and marine debris also pose direct threats to habitat integrity.

Overfishing: Unsustainable fishing practices, such as trawling and dynamite fishing, can cause physical damage to marine habitats and disrupt ecological balance. Overfishing reduces the population of key species, affecting the entire food web.

Habitat Destruction: Coastal development, dredging, and mining activities destroy marine habitats, leading to loss of biodiversity and ecosystem services. Mangroves, in particular, are often cleared for aquaculture and agriculture, resulting in significant habitat loss.
