The collapse of the world's banking system and the impending disaster of accelerating climate change are not separate phenomena. They are simply the most visible symptoms of a particular model of capitalism that will bring civilisation to its knees. But those symptoms will not get sorted unless and until we commit to a radical transformation of the way we create and distribute wealth in the world today

Fundamentally transforming the foundations of the economy is the biggest contribution we can make towards building a sustainable future. The current economic crisis may be painful, but it will be nothing compared with the crises we will face if we continue to grow in a way that threatens the life-support systems on which we rely

A combination of very rapid population growth over the last 50 years and reckless economic growth during the same time has stored up massive problems for societies the world over. No nation is immune. The scientific evidence tells us all we need to know: carry on with business-as-usual growth-at-all-costs, and we're stuffed

Absolutely love the new campaign from the Optimum Population Trust: do your bit for addressing climate change by having fewer children - or even no children. The lifetime CO2 emissions of a UK citizen amount to 750 tonnes (the equivalent - apparently - of 620 return flights between London and New York), so the extra 10 million by which our population will rise between now and 2074 will, over their lifetimes, emit around 7½ billion tonnes of CO2..."births averted" is probably the most single most substantial and cost-effective intervention that governments could be using

Any regeneration project that fails to put environmental and social benefits at its very heart is unlikely to achieve anything more than a very short-lived spasm of spurious prosperity

If something is sustainable, it means we can go on doing it indefinitely. If it isn't, we can't

We need to move away from crass, consumption-driven materialism by de-materialising status
