Study Warns , 'Extinction Wave' , Imminent in Madagascar.br Over 20 million years of evolution in Madagascar br could be wiped from the Earth if nothing is done to br save animal species on the island from extinction.br Our results suggest that an extinction wave br with deep evolutionary impact is imminent br on Madagascar unless immediate br conservation actions are taken, Dr Luis Valente, Naturalis Biodiversity br Center in Leiden, via 'The Guardian'.br 'The Guardian' reports that Madagascar is one of br the most diverse environments on Earth, with 90 br of its species found nowhere else on the planet.br Over half of Madagascar's br mammal species are currently br threatened by extinction.br It’s about putting things in perspective – we’re losing unique species traits that will probably never evolve again, Dr Luis Valente, Naturalis Biodiversity br Center in Leiden, via 'The Guardian'.br 'The Guardian' reports that Madagascar is home br to ring-tailed lemurs, fossa, the panther chameleon br and a vast array of other unique species.br 'The Guardian' reports that Madagascar is home br to ring-tailed lemurs, fossa, the panther chameleon br and a vast array of other unique species.br 'The Guardian' reports that Madagascar is home br to ring-tailed lemurs, fossa, the panther chameleon br and a vast array of other unique species.br 30 species of mammal have already gone extinct in br Madagascar, while over 120 of the 219 mammal species br alive on the island today are threatened by extinction.br 'The Guardian' reports that as lost species can br never return, the study looked at how long it would br take to return to previous levels of biodiversity. .br Lots of these species could be going br extinct in the next 10 or 20 years – br they cannot wait much longer. br You can quickly reach a point where br a species isn’t viable any more. , Dr Luis Valente, Naturalis Biodiversity br Center in Leiden, via 'The Guardian'.br The main message is that biodiversity br is not going to recover quickly.
