ECO-PROS Biodiversity - Species
How many species inhabit the planet? (CNN, 3/17/06) "Scientists agree on the sobering fact that most species that walked, crawled, swam or flew at some point are now extinct." "Scientists also agree that current extinction rates are far higher than "natural" ones because of human activities such as pollution, habitat destruction, and climate change." Endangered ...

ISSG's Global Invasive Species Database
They are particularly devastating to island ecosystems, which harbour much of the world's threatened biodiversity. Amongst these isolated populations, extinction rates are especially high. The invasive species problem is growing in severity and geographic extent as volumes of international trade and travel increase. In spite of these ...

Another example: the UN Environment Program, in its Global Biodiversity Assessment, estimated that current extinction rates are around 1000 times the natural (pre-human) rate! We don’t have to wait for ... that we only have a few hundred years until all rainforest is gone, and that we have an extinction rate of around 8000 species a year! what can I do? First of all, take a deep ...

Biodiversity Conservation System
Even on best available present knowledge, these estimates involve large degrees of uncertainty, and predictions of current and future extinction rates should be interpreted with very considerable caution. Pursuit of increased accuracy in the estimation of global extinction rates, however, whilst of great concern, is not a crucial activity ...

EDGE of Existence :: Mammal Extinctions
Evolutionarily distinct species appear to be more threatened with extinction than expected by chance, and many have already disappeared forever. It is estimated that global extinction rates are a thousand times higher than background rates shown by the fossil record.  Humans have been driving this mass extinction -- by direct hunting, habitat destruction, and introducing exotic predators -- ...

Species Extinction Threat Vastly Underestimated
"When we apply our new mathematical model to species extinction rates, it shows that things are worse than we thought," explained Melbourne. "By accounting for random differences between individuals, extinction rates for endangered species can be orders of magnitude higher than conservation biologists have believed." Melbourne's paper on the subject has just been published in Nature. Currently, ...
