Paleontologists study fossils and their relationship to existing plants and animals. The work of these scientists helps us understand both the present and the past. For example, using their knowledge of how fossils are distributed in sediments, paleontologists can help make accurate geological maps.
The animals who live in those habitats have adjusted to the local temperature so changing the climate drastically, may upset the living organisms there:)
