Coral Reefs and Environmental Challenges

The video discusses the resilience of corals near Miami Beach despite facing pollution, climate change, and ocean acidification. These corals could help repopulate Caribbean reefs, but they are threatened by sedimentation from human activities, including the expansion of the Panama Canal. The dredging process generates sediment that settles on reefs, causing significant damage. The video emphasizes the importance of protecting these corals to preserve biodiversity and the ecosystem services they provide.
