There are thirteen stories.The mastodon, great auk and ammonite in the previous stories have been extinct. This part mainly introduces the ancient mass extinction and its winding discovery process.The second part displays the current facts, in the increasingly fragmented Amazon rainforest, on the rapidly warming Andean slope, and in the surrounding waters of the Great Barrier Reef.
