The accelerating disappearance of Earth's species of both wild and domesticated plants and animals constitutes a fundamental threat to the well-being and even the survival of humankind, warns the founding Chair of a new global organization created to narrow the gulf between leading international biodiversity scientists and national policy-makers. In Norway to address an elite gathering of 450 international officials with government responsibilities in the fields of biodiversity and economic planning, Zakri Abdul Hamid offered his first public remarks since being elected in January to head the new Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) -- an independent body modeled on the Intergovernmental Panel on Climate Change.

Dr. Zakri, a national of Malaysia who co-chaired 2005's landmark Millennium Ecosystem Assessment and serves also as science advisor to his country's prime minister, cited fast-growing evidence that "we are hurtling towards irreversible environmental tipping points that, once passed, would reduce the ability of ecosystems to provide essential goods and services to humankind."

The incremental(增加的) loss of Amazon rainforest, for example, "may seem small with shortsighted perspective" but will eventually "accumulate to cause a larger, more important change," he said. Experts warn that ongoing climate change, combined with land use change and fires, "could cause much of the Amazon forest to transform abruptly to more open, dry-adapted ecosystems, threatening the region's enormous biodiversity and priceless services," he added.

"It has been clear for some time that a credible, permanent IPCC-like science policy platform for biodiversity and ecosystem services is an important but missing element in the international response to the biodiversity crisis," Dr. Zakri told the 7th Trondheim Conference on Biodiversity.
