The Great Barrier Reef is located off the coast of Australia and is the largest coral reef system in the world, stretching over 2,300 kilometers.

Algae are the primary producers in a coral reef ecosystem, using sunlight to produce food through photosynthesis.

Coral provides habitat for marine life, filters and cleans the water, and produces oxygen through photosynthesis.

Climate change, overfishing, and pollution are all major threats to coral reefs.

Coral bleaching occurs when coral expels its symbiotic algae, which provide it with food and color.

Coral reefs are the largest marine ecosystem in the world, covering an area of over 284,000 square kilometers.

Mangrove forests provide habitat for marine life, filter and clean the water, and protect coastlines from erosion.

Seagrass beds provide habitat for marine life, filter and clean the water, and produce oxygen through photosynthesis.

Kelp forests provide habitat for marine life, filter and clean the water, and produce oxygen through photosynthesis.

Burning fossil fuels releases carbon dioxide into the atmosphere, which dissolves in the ocean and forms carbonic acid, leading to ocean acidification.

Ocean acidification can cause coral bleaching, reduced shellfish growth, and disruption of marine food webs.

Reducing greenhouse gas emissions, reducing overfishing, and reducing pollution can all help to protect coral reefs and marine ecosystems.

Coral reefs and marine ecosystems provide food and livelihoods, protect coastlines from erosion, support biodiversity, and provide a variety of other benefits to humans.

Individuals can help to protect coral reefs and marine ecosystems by reducing their carbon footprint, choosing sustainable seafood, avoiding using plastic products, and supporting conservation organizations.

The future of coral reefs and marine ecosystems is uncertain, but there is still hope if we take action to reduce greenhouse gas emissions, reduce overfishing, and reduce pollution.
