Why are coral reefs in danger? How can we help?

Reef Cleanup

Coral reefs are in danger due to a variety of factors, including:

  • Climate change: As temperatures rise, coral reefs are subjected to more frequent and severe marine heat waves, which can cause coral bleaching and eventually lead to coral death.
  • Ocean acidification: As carbon dioxide levels in the atmosphere increase, more carbon dioxide dissolves into the ocean and makes the water more acidic. This can make it harder for corals to build their calcium carbonate skeletons, leading to slower growth rates and weaker coral structures.
  • Overfishing: Overfishing can disrupt the natural balance of reef ecosystems by removing key species from the food chain and damaging the reef structure.
  • Pollution: Runoff from human activities, such as agriculture and construction, can introduce pollutants and nutrients into the ocean that can harm corals and other marine life.

Overall, these factors are causing the decline of coral reefs around the world, which has significant ecological and economic consequences.

There are several ways you can help save reefs, including:

  • Use reef-safe products: Avoid using products that contain chemicals that can harm reefs such as oxybenzone and octinoxate, which are commonly found in sunscreens.
  • Reduce your carbon footprint: By using less energy and reducing your carbon emissions, you can help prevent climate change which can lead to coral bleaching.
  • Consume sustainable seafood: Overfishing can severely damage coral reefs. Choose sustainably sourced seafood, and avoid fish species that are known to live in or near coral reefs.
  • Use less plastic: Plastic pollution can harm coral reefs, so reduce the use of plastic in your everyday life.
  • Support conservation efforts: Support organizations that protect and preserve coral reefs through donations or volunteering.
