Although animal extinction is part of the natural cycle, humankind's presence on the earth has accelerated the rate at which species are disappearing.
The list of endangered species around the world is growing due to a range of causes from overhunting to a loss of habitat.
The best source of data on this is the Red List, compiled by the IUCN species programme. It's an amazing source of data, from the summary below through to huge geospatial files.
Efforts to sustain pressured populations through captive breeding programmes are showing some signs of success but man continues to exert a pressure on the environment which continues to endanger many species across the globe.
Just over 6% of the total species are in Brazil, reflecting the pressure that widespread deforestation is causing in the highly biodiverse region.
