The innumerable benefits provided by the Earth – everything from fresh water and clean air to productive soils, wild fisheries, and genetic resources - have been depleted at an unprecedented rate in the past 50 years, and in many cases humans are living on borrowed time unless they wake up, a group of scientific experts said today.
In presentations made jointly in 12 cities around the world, authors of the Millennium Ecosystem Assessment delivered a major report on the grim status of the services provided by the planets ecosystems and the consequences to human well-being. The report also outlined possible responses that might be adopted to improve ecosystem management and contribute to human well-being.
"This is a sobering report card - but one with useful and hopeful options" said Jane Lubchenco, the Wayne and Gladys Valley Professor of Marine Biology at Oregon State University, and one of the studys 1,360 authors from 95 countries. "Everyone in the world depends on nature and ecosystem services to provide the conditions for a decent, healthy and secure life," Lubchenco said.
"We hear a lot about various environmental problems and ecological issues, but this report integrates all of the changes underway and shows explicitly how they relate to human well-being," Lubchenco said. The severity of the problems, Lubchenco said, does not mean the situation is hopeless.
"Social change is not always steady and gradual," she said. "Once people better understand the situation and what we have to do, I think its possible we could see dramatic actions from many groups, including business, the general public, religious groups, and the scientific and political communities. The scientific community is offering an evaluation and suggested options. Now is a real opportunity for leadership."
The study said that three key changes must take place before major change is realistic.
People must first understand that the services provided by nature are not free and limitless. Local communities must have real influence in how conservation decisions are made, and end up with a fair share of the benefits. And the whole process must become more broad-based, not confined to a single government agency or one small part of a corporate bureaucracy.
Better understanding the real economic value of natural systems, and the bottom-line cost of losing them, will help, the study suggested.
Businesses must also learn that their long-term corporate survival may depend on protection of ecosystems, the report concluded, and they should explore changing consumer preferences and new business opportunities created by the demands of a changing world.

Species Richness – a false friend? Scientists want to improve biodiversity assessments

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
