However, some threats have arisen that endanger the coral reef species, Coral bleaching. This occurs when corals release the algae living inside of them, causing a color change. Although some corals can recover from the bleaching if their environment improves, an extended period can lead to coral death. Coral Reef Bleaching often stems from three factors: Rising ocean temperatures, changes in water quality, and increased sunlight. For instance, according to Icriforum.org, last year was the hottest on record, resulting in a 1.5 °C increase as well as triple the number of marine heatwaves. This extreme heat stress causes the coral reefs to expel the zooxanthellae, preventing them from growing and reproducing, leading to these mass bleaching events.  

Globally, coral reefs may go extinct if we do not stop coral reef bleaching. Numerous fish populations would decline as a result, and habitats for thousands of marine species would be destroyed. The impact would be observed by millions of people who depend on reefs for their food, money, and tourism. Coastal regions would also be more vulnerable to storm damage and sea level rise in the absence of coral reefs. Furthermore, we might lose out on possible medical advancements made by reef organisms. Ignoring coral bleaching, an obvious sign of climate change, would have disastrous consequences for both the environment and human life.

However, it is not too late to prevent the spread of Coral Bleaching. Global goals we can set are to commit to Net zero by 2035, emission reductions of 30%, and no fossil fuel infrastructure. In addition, more practical goals could be using reef-friendly sunscreen, safe diving and snorkeling, and also being sustainable in our everyday lives. These could range from recycling and disposing of trash properly, saving energy, or using more environmentally friendly modes of transportation. Small, sustainable changes in our daily lives can eventually lead to a positive impact on our marine ecosystem.
