The 6th Extinction and Protected Areas

The 6th Extinction
A mass extinction is under way. Human activity, not natural phenomenon, is the difference between this extinction and the five previous big extinctions that have occurred in Earth's history. The current extinction is driven by habitat loss, overexploitation of species, invasive species and pollution. All of these, the result of humans.

The current extinction rate is between 1,000 and 10,000 times higher than the natural rate. (International Union for Conservation of Nature, IUCN) Current estimates put the extinction rate at roughly 30,000 species per year which is about three per hour. By the end of this century, about half of Earth's plant species could be gone. (Pitman and Jorgensen, 2002) For an assessment of global biodiversity, refer to the IUCN Red List. read more

The Recession and Short Term Trends In Energy Demand

The global economy and energy system are interdependent strands where changes in one will often cause fluctuations in the other. This relationship was highlighted by the recent economic crisis which saw cumulative effects in other spheres including world energy demand.

Information for the Virtual Water Discussion and Water Security

The World Water Council notes that the right to water "entitles everyone to sufficient, safe and acceptable, physically accessible and affordable water for personal and domestic" functions. Yet, the consumption and production of water for personal and domestic purposes depend mainly on the water and water transformation processes available for industry and agriculture. Indeed, water use in industry and agriculture has become so critical within and between countries that the term virtual water has been coined to distinguish it as a unique topic of discussion.

Energy Efficiency Measures and Global Climate Change Mitigation

Two recent events held in Washington, D.C. highlighted the importance of efficiency measures to mitigate global climate change's (GCC) effects. At the Design X Tomorrow: The Future of Technology and Sustainability and McKinsey & Company's launch of Unlocking energy efficiency in the U.S. economy, the common message was simple: increasing the efficiency of energy consumption should be a major priority.

Calculating a Carbon Footprint

Not too long ago, the concept of a Carbon Footprint was a foreign one. But as global climate change theory has gained traction in the general public, carbon footprint has become common lingo. Online calculators which account for ones personal carbon emissions have emerged as a popular tool for the climate-minded to track and reduce their greenhouse gas emissions. These calculators are so prevalent that if you search Google, you'll find a wide selection waiting for your personal energy and transportation data. Here's the problem though: not all carbon footprint calculators are created equal. So to help you parse out the good from the bad, and assess the accuracy of a quick and dirty approach, I tested nine different calculators.
