Dr. Chen, a biologist, observes that a coral reef loses 12% of its live cover each year due to warming oceans. If the reef initially covers 2,500 square meters, what area remains after three years?

**Why Coral Reefs Face an Urgent Decline—And What Science Reveals** Every year, growing ocean temperatures threaten one of Earth’s most vital ecosystems. Coral reefs, vibrant underwater cities supporting marine life and coastal protection, face accelerating loss—losing up to 12% of their live cover annually. For scientists tracking this shift, Dr. Chen, a biologist, observes that coral cover declines steadily when warming waters trigger stress and bleaching. With temperatures rising and ocean conditions changing faster than many species can adapt, understanding this loss is critical to gauging the reef’s near-future health. Recent data shows a reef initially spanning 2,500 square meters could face steep shrinkage within just a few years. This decline isn’t just environmental—it’s a growing concern for coastal economies, biodiversity, and climate resilience. As awareness spreads, people across the U.S. ask: What happens to coral cover when loss averages 12% per year? And what does this mean for the reefs we depend on? ---
