This is because he feels intuitively the dangers to which hard-headed scientists like Prof Steve Jones, whom you quote, are blind.

 However, most people - including the Prince of Wales himself - are leading or striving after non-sustainable lifestyles. If all the world's fathers were to give their children a car for their 17th birthday, as he did, the planet's life-supporting ecosystems would soon collapse under the strain! [Birthday Prince has a date with a diesel, 21 June 1999]. 

In this we are encouraged by a billion dollar advertising industry serving an economic system that is inherently dependent on us pursuing non-sustainable lifestyles!

 The truth of the matter is that our economic system itself, along with many of the values it is based on, are non-sustainable.

 This means that unless we start to make some very radical changes fairly soon we are doomed.

 Although I think he has yet to appreciate the full implications of his intuition, Prince Charles is on the right track. He who speaks to the flowers is the one we should listen to, rather than he who would genetically manipulate them. 

If we listen to that arrogant, scientific know-it-all, Prof. Steve Jones, we are doomed and will soon be off to join the dinosaurs.
