"The food prices are going up – everyone thinks it’s to do with not enough food but it's really that demand is too great, [there are] too many people. It’s embarrassing and no one knows how to handle it because nobody wants their family life to be interfered with by Government... overpopulation is to blame for many of the problems afflicting millions of people around the world... It seemed to me that most religions attributed the world to some special creation and I said, ‘Well, look, if you believe God created the world, you ought to take an interest in its wellbeing... People don’t realise it is the species that matter – not the individual – from the conservation point of view. You’ve got to be fairly hard-hearted about it. Conservation is not a romantic business. It’s a very practical business, trying to ensure as many different species of wildlife can exist, and which means in some cases controlling some so the others can have a better chance."
