In a study on more than 71,000 animal species around the world, researchers discovered that about 48% are declining.  The researchers analyzed population data on mammals, reptiles, amphibians, birds, fish and insects.  These findings were published in the journal Biological Reviews.  According to the World Wildlife Fund, human activities including land, water and energy use are driving declines in biodiversity. Agriculture alone is responsible for 90% of deforestation and 70% of freshwater consumption globally. Although extinction is a natural process, extinction rates are now 1,000 to 10,000 times faster than the rates of natural extinction, WWF reported.
