I think we will work our way towards a position that says that having more than two children is irresponsible.

...living more sustainably means living happier, more balanced and potentially more fulfilled lives than most of us 'choose' to live today, whatever Jeremy Clarkson may have to say about that!

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'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

Climate change is not an environmental issue, but much more to do with security and economics

What may be possible for a minority of humankind, albeit at great cost, simply cannot work for the humankind. Our kind of progress depends on lacerating the Earth,on gouging out its riches, on stripping is life-sustaining skin of soil and forest

Keeping people on side is a precondition of making any progress on sustainability issues
