Coral Bleaching Threatens Ocean Life Support

Coral reefs cover less than 0.2% of the ocean but house 30% of all marine species.

That's like fitting the population of New York City into a single neighborhood. But here's the problem.

When ocean temperatures rise just half a degree above normal, corals expel their colorful algae partners

and turn ghost white. This bleaching isn't just about losing pretty colors. It's coral starvation

in real time. Without their algae roommates, corals can't produce food and start dying

within weeks. The Great Barrier Reef lost half its coral cover in just 27 years.

Even crazier, these reefs protect 150,000 kilometers of coastline and feed 500 million

people worldwide. We're not just losing underwater gardens, we're losing entire life support systems
