"Life is all about contrast, and who live in the cities all year around, fed up with the walls of the house in front of them, the street noise, shop windows, the stay behind the scenes after a long day at the workshop, the office, the artificial and urban life in one word, they naturally wish an unspoiled and wild nature, the more unspoiled and wild the better, where the trees are not cut down, animals not killed, landscape not spoiled to be able to walk and observe freely,refreshing mind and
spirit… And that is why people say in USA that a lawyer is a better lawyer, the engineer is a better engineer, the architect is a better architect, the tailor a better tailor after coming back from one of the National Parks. If the whole world could enjoy the National Parks, we could say that the social matter would be resolved". (Pedro Pidal y Bernaldo de Quirós, 1932)
