Good morning, everyone. Today we're going to discuss the impact of climate change on marine ecosystems. Specifically, I want to focus on coral bleaching, which is a stress response caused by rising water temperatures. When the water gets too warm, corals expel the algae living in their tissues, causing them to turn completely white. This not only affects the corals themselves but also the fish that depend on them for shelter and food. Interestingly, some corals have shown resilience by adapting to warmer waters, but this adaptation is slow and may not keep pace with the rapid rate of temperature increase. Therefore, urgent action is needed to reduce carbon emissions.
❓ 讲师对于珊瑚白化现象有何说法？
A. 这是由水温骤降引起的。
B. 这导致珊瑚失去颜色并变白。
C. 它只影响珊瑚，不影响其他海洋生物。
D. 由于珊瑚的适应性，这一现象已不再发生。
✅ 正确答案
It results in corals losing their color and turning white.
