What were Caribbean coral reefs like before humans?
Paleontology and Paleobiology
To understand the present and predict the future we need to learn from the past. Ancient tree fossils from a higher-carbon period millions of years ago may help Smithsonian scientists predict how forests will respond to future climates. Similarly, the remains of corals, sponges, snails and sharks just a few thousand or hundred years old can help reconstruct what tropical reef ecosystems were like before humans — and perhaps aid the conservation of these radically altered these ecosystems.
