La città come “sistema”

Possiamo immaginare quindi la città come un “sistema” che deve essere in grado di fornire ai suoi abitanti, instaurando un equilibrato rapporto tra natura e città, le risorse offerte dall’ecosistema preservandone le caratteristiche. In altri termini quindi la città deve garantire efficaci ed equi sistemi di gestione dei beni comuni quali aria, acqua, terra ed energia, indispensabili per la vita dell’uomo.

A questo proposito Herbert Girardet ha applicato il concetto dei processi circolari presenti in natura al sistema urbano proponendo l’idea di “metabolismo circolare”.1 Il “metabolismo lineare” che caratterizza attualmente le città, e che trasforma le risorse in rifiuti da smaltire attraverso processi complessi ed energivori, potrebbe, secondo Girardet, essere trasformato in “metabolismo circolare”: l’evoluzione tecnologica e la crescente consapevolezza sulle questioni ambientali forniscono all’uomo gli strumenti per riciclare i rifiuti derivati da acqua, cibo, carburante, e materiali in modo da trasformarli nuovamente in risorse e operare in questo modo la chiusura del ciclo vitale della città.

Economists say that with the internationalisation of the Euro, Japanese yen, British pound, Australian dollar, Canadian dollar and the RMB, countries are increasingly bypassing the US dollar and entering into currency swap agreements.

    I love the theatre losartan potassium online pharmacy For his role as the Grinch, Jim Carrey endured five months of a “hair” suit, consisting of individually dyed yak hairs hand sewn onto a lycra spandex suit. It took makeup artist extraordinaire Rick Baker 4 months to make it. “There was no skin to be had,” Carrey said in an interview. “Literally everything was covered. It was impossible to scratch your nose. It was literally a lesson in Zen.” As for his face, Carrey was slathered in makeup and rubber and even had to wear oversized contact lenses, which, he explained, “really push you over the edge.”
