I think we'd be very foolish to expect that we can just import everything from somewhere else and imagine that that's going to last for ever and ever and ever

There is very good evidence indeed that one of the major reasons for this horror in Syria was a drought that lasted for about five or six years, which meant that huge numbers of people in the end had to leave the land.

I think we're going to find, with climate change and everything else, things like global warming and goodness knows what else and the cost of fuel for a start, that things are going to become very complicated.

The world's forests need to be seen for what they are - giant global utilities, providing essential public services to humanity on a vast scale. They store carbon, which is lost to the atmosphere when they burn, increasing global warming. The life they support cleans the atmosphere of pollutants and feeds it with moisture. They act as a natural thermostat, helping to regulate our climate and sustain the lives of 1.4 billion of the poorest people on this Earth.

If you think about your and my grandchildren, this is what really worries me. I don't want them - if I'm still alive by then - to say, 'Why didn't you do something about it?', when you could have done.
