[Science News Blog * Science News and Trends *] An alarming survey, The Millennium Ecosystem Assessment, reveals that approximately 60 percent of the ecosystem services that support life on Earth - such as fresh water, capture fisheries, air and water regulation, and the regulation of regional climate, natural hazards and pests - are being degraded or used unsustainably. Scientists warn that the harmful consequences of this degradation could grow significantly worse in the next 50 years.

[Speed of Thought...] Martian life might threaten human mission...: So astronauts could inadvertently bring the life back to Earth, with potentially dangerous consequences. "The possibility of transporting a replicating life form to Earth, where it is found to have a negative effect on some aspect of Earth's ecosystem" would present the greatest biological risk, the team wrote.

Farmers in the Chinese province of Liaoning are uncovering, in a series of exquisitely preserved fossils, evidence of an entire ecosystem of plants, insects, fish, turtles, small mammals and birdlike dinosaurs never seen before. The Dilong paradoxus, a five-foot-long early relative of Tyrannosaurus,with rudimentary feathers evidently meant for warmth, not flying.

Full climate writings and links to news can be found at http://www.climateark.org/blog/ -- the best and most important of which will be sent to this new list.
[Thecatsdream.com] The Cat's Blog: LIFE ON EARTH: “Any progress achieved in addressing the goals of poverty and hunger eradication, improved health, and environmental protection is unlikely to be sustained if most of the ecosystem services on which humanity relies continue to be degraded,” said the study, Millennium Ecosystem Assessment (MA) Synthesis Report, conducted by 1,300 experts from 95 countries. It specifically states that the ongoing degradation of ecosystem services is a road block to the Millennium Development Goals agreed to by the world leaders at the United Nations in 2000.
[Eco-portal.com] Earth Blog: All available scientific evidence would suggest that the Earth has already overshot the amount of native forests and other natural terrestrial ecosystems that can be lost while reliably and adequately maintaining ecological processes such as water retention, wildlife habitat, soil formation, atmospheric cycles, etc. The type of large scale restoration of Scottish native woodlands discussed in the following article will have to occur globally as a matter of some urgency.
