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 composed of coral polyps, which are small marine animals that secrete calcium carbonate to form the reef structure. These biodiverse habitats provide crucial shelter and food for countless marine species, including fish, mollusks, and crustaceans, and are often referred to as the 'rainforests of the sea' due to their rich biodiversity. Coral reefs are highly sensitive to changes in water temperature and quality, making them vulnerable to climate change and human activities such as pollution and overfishing. Their preservation is vital not only for marine life but also for coastal protection and the livelihood of communities that depend on reef resources.
