Nikla: Coral reefs are like diving in a huge aquarium, and it's just bursting with color. She says the first thing you notice is actually the colors. And then if you get closer to the reef, there are hundreds of different species. Garrethow: You would expect diving on a reef to be quite quiet, but it's actually really loud.
Melvyn Bragg and guests discuss the simple animals which informed Charles Darwin's first book, The Structure and Distribution of Coral Reefs, published in 1842. From corals, Darwin concluded that the Earth changed very slowly and was not fashioned by God. Now coral reefs, which some liken to undersea rainforests, are threatened by human activity, including fishing, pollution and climate change.
