Parts of the Endangered Species Act, which has protected nature in the United States for 3 1/2 decades, soon may be extinct. The new regulations, which do not require Congress’ approval, would reduce the numbers of mandatory, independent reviews government scientists have been performing for 35 years, according to a draft first obtained and reported by The Associated Press.

About half the world’s apes, monkeys, and other types of primates are in danger of extinction, according to a new study that predicts a bleak future for many of humankind’s closest relatives.

Primates are falling prey to intense hunting and rapidly losing their habitats to deforestation, the study released Monday said.

Endangered species could become extinct 100 times faster than previously thought, scientists warned yesterday in a bleak reassessment of the threats to global biodiversity. They say methods used to predict when species will die out are seriously flawed and dramatically underestimate the speed at which some will disappear.

The findings, presented in the journal Nature, suggest that animals such as the western gorilla, the Sumatran tiger and Malayan sun bear, the smallest of the bear family, may become extinct much sooner than conservationists had feared.

The world’s species are declining at a rate “unprecedented since the extinction of the dinosaurs”, a census of the animal kingdom has revealed. The Living Planet Index out today shows the devastating impact of humanity as biodiversity has plummeted by almost a third in the 35 years to 2005.

The report, produced by WWF, the Zoological Society of London (ZSL) and the Global Footprint Network, says land species have declined by 25 per cent, marine life by 28 per cent, and freshwater species by 29 per cent.

HUMANS are causing such unprecedented climatic change and mass extinctions it is creating a new geological age, according to a leading environmental scientist.

The planet is already amid a “human-induced mass extinction event” which is defining a new geological age known as the Anthropocene, says Professor Will Steffen, director of the Centre for Resource and Environmental Studies at Canberra’s Australian National University.
