Corals can become stressed by a variety of factors, including changes in water temperature, pollution, overexposure to sunlight, sedimentation, and physical damage from storms or human activities. When corals are stressed, they expel the algae living in their tissues, causing them to turn white, a phenomenon known as coral bleaching. If the stress is prolonged or severe, corals may die. It is important to protect coral reefs and their surrounding environments to help reduce these stressors and ensure the health and survival of coral ecosystems. **
