The Millennium Ecosystem Assessment , released in 2005, is an international synthesis by over 1000 of the world's leading biological scientists that analyzes the state of the Earth’s ecosystems and provides summaries and guidelines for decision-makers. It concludes that human activity is having a significant and escalating impact on the biodiversity of world ecosystems , reducing both their resilience and biocapacity . The report refers to natural systems as humanity's "life-support system", providing essential " ecosystem services ". The assessment measures 24 ecosystem services concluding that only four have shown improvement over the last 50 years, fifteen are in serious decline, and five are in a stable state overall, but under threat in some parts of the world.

Growing plants to make electricity is a more efficient and environmentally sound way to power vehicles than biofuels, according to a study meant to spark a debate over energy policy. The study 's authors modeled how far different classes of cars could go based on the available energy from a unit of land and found that bioelectricity--burning biomass to make electricity--far outperforms ethanol. The paper, published on Thursday in Science, found that bioelectricity delivered 81 percent more distance per unit area of crop land than ethanol. Greenhouse gas emissions per area of land were 100 percent less than cellulosic ethanol. (Click here for PDF of results .)

Seen from space the Earth is covered in a blue mantle. It is a planet on which the continents are dwarfed by the oceans surrounding them and the immensity of the marine realm. Do you know what is happening to your ocean beyond the beach? © Greenpeace/Vadim
