How can glaciers be useful to people?
Glaciers are useful to people because some of the best preserved fossils are found within them. More importantly, though, glaciers are of great importance to many people because they reflect large amounts of solar radiation due to their high albedo which reduces global warming. Also, glaciers are extremely important for people with investments in or living in coastal areas because they serve as a storage of water that if melted will inundate many current coastlines.
