The video explains biomes, large geographic regions defined by climate, animals, and plants. It categorizes biomes into terrestrial and aquatic, detailing types like forests, tundras, deserts, and marine environments. The video also highlights threats to tropical rainforests, such as deforestation and climate change, and emphasizes the ecological importance of biomes in understanding ecosystems and conservation efforts.

What is a biome?
