Coral reefs, despite constituting a small fraction of the ocean ecosystem, play an indispensable role in both marine and human life. The disappearance of these vital ecosystems would lead to several catastrophic consequences. Here are the three most significant threats that would emerge without coral reefs:
- Coral reefs are primary producers of oxygen in the ocean, contributing to about half of its total oxygen. Without them, the survival of marine life, and in turn, life on earth would be at risk.
- Coral reefs are home to an incredibly diverse array of marine species. Their disappearance would disrupt the ecological balance and lead to the suffering of billions of these species.
- Coral reefs are a significant source of livelihood for millions of people around the world. They also contribute to the food supply and have a profound impact on the economy. Their absence would lead to economic instability and food scarcity.
