Ecological footprint (Human) ecological footprint is a measurement of anthropogenic impact on earth. Two fields of science scope human impact on Earth; they are geospheric and biospheric sciences. Human activity is measured through ecological footprint research. Our activity is now the leading cause of climate change.  Our impact is now threatening total global collapse.   Since the 1950s the human footprint has grown so massive that it has caused Earth to enter into an new geological epoch called The Anthropocene.

Chile: Citizens Reject the Hidroaysen Dam Project On Monday, May 9, the Environmental Evaluation Commission, meeting in Coyhaique, a city in the Chilean Patagonia, and composed of 12 appointed officials in President Sebastian Pinera's government, approved the hydroelectric plant Hidroaysen, [es] a merger between Spanish-Italian Endesa and the Chilean Colbun.

coalition of the willing Posted on 10. Dec, 2010 by fabio_barone in Open culture, The movement What is our situation, today? We could dream of a planetary nervous system, of a united humanity, of a species cooperating on a marvelous magic satellite. Living Planet Report The Living Planet Report is the world's leading, science-based analysis on the health of our planet and the impact of human activity. Knowing we only have one planet, WWF believes that humanity can make better choices that translate into clear benefits for ecology, society and the economy today and in the long term. This latest edition of the Living Planet Report is not for the faint-hearted. One key point that jumps out is that the Living Planet Index (LPI), which measures more than 10,000 representative populations of mammals, birds, reptiles, amphibians and fish, has declined by 52 per cent since 1970.
Douglas P. Wheeler - Our People - Hogan Lovells Doug has helped to shape many of the laws and programs that now constitute national environmental policy, including habitat conservation planning pursuant to the Endangered Species Act, conservation and mitigation banking, and transferable development rights. From 1991-1999, Doug served as California’s Secretary for Resources. As a member of the Governor’s cabinet, he was responsible for all of the state’s natural and cultural resource programs administered through 18 departments, conservancies, boards, and commissions with combined budgets of nearly $2 billion and a total staff of 13,000. During his tenure, Doug developed nationally recognized strategies to integrate economic and environmental goals and to effectively manage the state’s natural resources in the face of rapid growth and development. Doug has worked exclusively with natural resource and environmental issues since joining the U.S.
the environmentalists: Home known issues, new qualities Pollution, the destruction of habitats, even the extinction of whole species are no new phenomena. What is new, is the reach and the permanence of the changes, humans inflict on the environment today. Read more...

People often get disillusioned by sustainability, saying it is too complicated to understand, when in actual fact it is really quite simple.
Standing up for Nature Most unfairly ignored UK bird? Photo: Chris Cant via wikimedia commons What is the UK’s most unfairly ignored bird? Well according to you, and your votes, it is the Stock Dove (and I agree with you)! This wasn’t the most popular poll on this blog, but nearly 150 of you responded and this was the result: Stock Dove – 33% Ecological Footprint Ecological Footprint What Is the Ecological Footprint? The Ecological Footprint is rooted in the fact that all renewable resources come from the earth. It accounts for the flows of energy and matter to and from any defined economy and converts these into the corresponding land/water area required for nature to support these flows. The Ecological Footprint is defined as "the area of productive land and water ecosystems required to produce the resources that the population consumes and assimilate the wastes that the population produces, wherever on Earth the land and water is located."1 It compares actual throughput of renewable resources relative to what is annually renewed.
Ecological Footprint 2.0 by Worldchanging Intern, Alex Lowe: To understand the subtleties and difficulties in ecological footprinting, think of accounting. In the past few years, Enron's collapse and the scandals that surrounded WorldCom gave people a small glimpse into the intricacies of accountancy. To the uninitiated, the swirl of news reports circa 2003 must have posed several questions: How hard can accounting really be?
