Biodiversity studies not just on the surface but probably the fossils. Cement industries may caused lost of species and may be extincts

Humble snails are no match for the might and indifference of the global cement industry. So it has proved for the now extinct Plectostoma sciaphilum, a rather beautiful snail that lived only on a single limestone hill in Peninsular Malaysia. A cement company blew up the entire hill and all remaining molluscs with it. All that is left of its former habitat is a big hole in the ground filled with water.

The neighbouring isolated hills are being quarried by Malaysian multinational YTL, owner of Wessex Water, where snails such as the bizarrely-shaped Hypselostoma elephas are in critical danger.
