World Ocean Day: Protecting and restoring coral reefs
World Ocean Day takes place annually on the 8th of June and aims to unite and rally the world to protect and restore our planet. The Day supports collaborative conservation, working with its global network of youth and organisational leaders in over 150 countries. Coral reefs are one of the most diverse and important ecosystems on Earth. They provide food and shelter for a wide variety of marine life, and they also play a vital role in protecting coastlines from erosion. However, coral reefs are under threat from global warming and need to be protected and restored.
Coral reefs and global warming
Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also a source of food and new medicines with over half a billion people depending on reefs for food, income, and protection.
As the Earth’s temperature rises, corals are becoming more susceptible to bleaching. Bleaching occurs when corals expel the algae that live inside their tissues. These algae provide the corals with food and nutrients, so when they are expelled, the corals starve and eventually die.
In the past few decades, coral bleaching has become more frequent and severe. This is due to the fact that global warming is causing the Earth’s oceans to warm at an alarming rate. In 2016, for example, the Great Barrier Reef, the world’s largest coral reef system, experienced its worst bleaching event on record. If global warming continues at its current rate, it is estimated that up to 90% of coral reefs could be lost by the end of the century. This would have a devastating impact on marine ecosystems and coastal communities around the world.
Innovations helping to protect and restore coral reefs
There are a number of things that can be done to help protect coral reefs from global warming and researchers are developing innovative solutions to protect and restore these endangered habitats. For instance, the US20220322643 A1 patent describes a method for growing coral in a controlled environment, allowing for the mass production of corals. The system ensures that the corals are grown in optimal conditions, resulting in a high-quality product that is free of heavy metal contamination. This provides a way to produce corals sustainably and transplant these to reefs that have been damaged by bleaching or other stressors.

Another area of research is the development of new methods for breeding corals that are more resistant to heat stress. This involves exposing corals to heat stress in a controlled environment. The corals that survive the heat stress are then bred to create a new generation of corals that are more resistant to heat stress.
Finally, innovators are looking at ways to adapt existing technologies to monitor coral reefs. For example, drones are being equipped with cameras that can be used to take pictures and videos of reefs. These can then be used to track the health of the reefs and identify any problems that may be developing.
The future of coral reefs is uncertain, but there is still hope that we can take steps to protect them through ongoing research and innovations. These innovations are just a few examples that can help to restore and protect coral reefs, with the hope to ensure that these valuable ecosystems continue to thrive for many years to come.
