Dangerous climate change... It's important not to be alarmist but it is very important to be alarmed

Consuming three planets' worth of resources when in fact we have one is the environmental equivalent of childhood obesity - eating until you make yourself sick.

I can't admit to myself that the creation of a Palestinian state won't happen. What I know is that with each passing year it gets more and more difficult to happen, not least because there is more and more bloodshed, generation upon generation.

We are living as if we had three planets' worth of resources to live with rather than just one. We need to cut by about two-thirds our ecological footprint. For that we need one planet farming as well as one planet living - one planet farming which minimises the impact on the environment of food production and consumption, and which maximises its contribution to renewal of the natural environment

In the future, every industry should be an environmental industry. In a world where energy and carbon emissions are constrained, every business must take resource productivity seriously
