2007 IUCN Red List of Threatened Species - Extinction crisis escalates

Life on Earth is disappearing fast and will continue to do so unless urgent action is taken, according to the 2007 IUCN Red List of Threatened Species. There are now 41,415 species on the IUCN Red List and 16,306 of them are threatened with extinction, up from 16,118 last year. The total number of extinct species has reached 785 and a further 65 are only found in captivity or in cultivation. One in four mammals, one in eight birds, one third of all amphibians and 70% of the world's assessed plants on the 2007 IUCN Red List are in jeopardy. The IUCN Red List of Threatened Species is widely recognized as the most reliable evaluation of the world's species. It classifies them according to their extinction risk and brings into sharp focus the ongoing decline of the world's biodiversity and the impact that mankind is having upon life on Earth.
