(PhysOrg.com) -- Anthropogenic, or human generated, sounds have the potential to significantly affect the lives of aquatic animals - from the individual animal`s well-being, right through to its reproduction, migration and even survival of the species. http://www.physorg.com/news156099748.html Biology Thu, 12 Mar 2009 18:03:37 EST news156099748 (PhysOrg.com) -- In general, population extinction is a natural process. For one reason or another, an estimated 99.9% of all species that have lived on Earth are now extinct. However, the reasons for a species going extinct are complex, varied, and changing. Ever since the human population began dispersing throughout the Earth 100,000 years ago, the extinction rate has increased dramatically - as much as 1,000 times, by some estimates - putting us in the midst of a modern extinction called the Holocene extinction event. http://www.physorg.com/news151059872.html Physics Tue, 13 Jan 2009 09:04:32 EST news151059872
