Global ecological sustainability is imminently threatened by a massive ecological bubble. Global terrestrial, atmospheric, aquatic and marine ecosystems are no longer adequately intact to maintain conditions for life. The mark of progress and an equitable, sustainable economy is not how fast the economy grows at the expense of destroying these ecosystems. It is whether the basic needs and more of all Gaia's people and creatures are being met, while maintaining forever the ecological sustainability of their shared ecosystem habitats. [continue]

According to the Conservation of Energy Principle, we can neither create nor destroy energy. This means we will always have as much energy as we ever had. So, how can we experience an energy crisis? Our crisis develops from another law of energy: The Entropy Law. It states that energy use always results in some overall loss of availability, quality, or order. Physics characterizes such loss as an increase of entropy. This is where informed energy discussions begin. [continue]
Amongst scientists, James Hansen has long been one of the clearest voices for strong action against climate change. Yet now he advocates replacing coal with wood from vast tree plantations, burning the wood and capturing and sequestering the carbon dioxide. He also supports the idea that we should burn vast amounts of biomass in order to gain energy as well as charcoal in the hope that digging the charcoal into the soil will permanently sequester the carbon and make the soil more fertile, a concept known as 'biochar'.
