It's not enough simply to wear the badge of corporate responsibility. Business must accept that real change is the only response to climate change and other environmental crises

We are now running out of time, and the question now is not what is happening to the climate, but how bad will it be before the world starts doing enough?

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.

"The ultimate recession": a recession caused not by failed regulation and bankers' greed, but by very high oil prices, food and water shortages, disappearing forests, accelerating climate change, forced migration and mass civil disruption...The long and the short of it, unfortunately, is this: more politicians still believe that economic recovery depends on continuing to live beyond our means (financially and ecologically) than on learning to live within our means. And that's why the ultimate "Perfect Storm" recession still looms on the horizon

Peace, non-violence, human rights and the environment - if only everybody saw these as the seamless whole that they are

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

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