Estuaries and Coral Reefs Concepts

The video explores estuarine and marine biomes, focusing on estuaries where freshwater meets saltwater, creating unique ecosystems. It discusses the diverse flora and fauna in estuaries, including mangroves and various marine species. The video highlights human impacts like pollution and conservation efforts. It also covers coral reefs, their biodiversity, and threats from climate change and human activities. The video concludes with reflection questions on the significance of biomes.
