One of the main reasons for the conflict in Syria, and the terrorism that it's spawned, is climate change and drought.

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.

My Rainforests Project ... has three main elements. Firstly, to determine how much funding the rainforest countries need to re-orientate their economies so that the trees are worth more alive than dead.

All I'm saying is that there is a price to be paid at the sharp end.. environmentally and everywhere else.. for the food that is produced in a particular way.

Fast food may appear to be cheap food and, in the literal sense it often is, but that is because huge social and environmental costs are being excluded from the calculations. Any analysis of the real cost would have to look at such things as the rise in food-borne illnesses, the advent of new pathogens, antibiotic resistance from the overuse of drugs in animal feed, extensive water pollution from intensive agricultural systems and many other factors. These costs are not reflected in the price of fast food.

We should be treating, I think, the whole issue of climate change and global warming with a far greater degree of priority than I think is happening now.

Do you seriously expect me to be the first Prince of Wales in history not to have a mistress?
