Then & Now
🌍 The geography you'll learn is the same one your phone's GPS is using right now.
Coral reefs are vibrant underwater ecosystems that provide essential habitats for a diverse array of marine life. Comprised of living coral polyps and the calcium carbonate structures they secrete, these reefs support over 25% of all marine species, despite covering less than 1% of the ocean floor. Coral reefs are often referred to as the 'rainforests of the sea' due to their biodiversity. However, they are increasingly threatened by climate change, pollution, and overfishing, making conservation efforts vital for their survival and the health of global oceans.
