We're never going to scare people into living more sustainably! We have to be able to demonstrate just how dynamic and aspirational such a world could be

The huge arrogance of the companies developing GMO crops and their determination to destroy the line of accountability which links the developer to the product is breath-taking. When something goes wrong, as it inevitably will, there will be a great benefit to those who have taken a stance against genetically modified organisms.

I am unapologetic about asking people to connect up their own responsibility for their total environmental footprint and how they decide to procreate and how many children they think are appropriate.

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

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