“Great things are done when men and mountains meet; This is not done by jostling in the street. -William BlakeThis admirable couplet should be posted in conspicuous places all over England. The truth it embodies is threatened by two parties of opinion: on the one hand by those who hold it as a sin against nature to try and control the increase of population in any way and on the other by those who believe in 'growth', the pursuit at all costs of a standard of living which entails more and more industrialization and urbanization. If the believers in nature have their way, England will in the end be so full of people that they will be jostling each other even on mountains: if the believers in 'growth' have their way, the whole country will be covered with streets and we shall hardly be aware that mountains exist.”
