The 'LPI'

The Living Planet Index, which is an attempt to measure the health of worldwide biodiversity, showed an average decline of about 30% from 1970 to 2005 in 3,309 populations of 1,235 species. An index for the tropics shows an average 51% decline over the same period in 1,333 populations of 585 species.
