Then & Now
🌍 The geography you'll learn is the same one your phone's GPS is using right now.
Coral reefs are intricate underwater ecosystems formed by colonies of tiny marine animals known as corals. These reefs, often referred to as the 'rainforests of the sea,' provide habitat and shelter for a diverse range of marine species, including fish, mollusks, and sea turtles. Coral reefs thrive in warm, shallow waters where sunlight penetrates, facilitating photosynthesis by the symbiotic algae that live within coral tissues. However, coral reefs face significant threats from climate change, pollution, and overfishing, prompting urgent conservation efforts to protect these vital ecosystems.
