Today, we're going to discuss the impact of climate change on coastal ecosystems. One key point is that rising sea levels lead to saltwater intrusion, which damages freshwater wetlands. This affects the habitat of many bird species. Additionally, warmer ocean temperatures cause coral bleaching, reducing biodiversity. However, a less obvious effect is the increase in storm intensity, which erodes beaches and destroys nesting sites for sea turtles. Interestingly, some mangrove forests are adapting by migrating inland, but this is often blocked by human development. Overall, the most immediate threat is not temperature rise itself, but the rate of change, which outpaces species' ability to adapt.
❓ Согласно лекции, какая угроза является самой непосредственной для прибрежных экосистем?
A. A. Повышение температуры океана, вызывающее обесцвечивание кораллов.
B. B. Увеличение интенсивности штормов, размывающих пляжи.
C. C. Быстрые темпы изменения окружающей среды, превышающие способность видов к адаптации.
D. D. Проникновение солёной воды, наносящее ущерб пресноводным водно-болотным угодьям.
✅ 正确答案
C. The rapid rate of environmental change exceeding species' adaptation.
