Stamattina sono andato al superette sotto casa per prendere una confezione di sei bottiglie d’acqua, marchio della catena. (A casa nostra si beve acqua gasata). Ogni bottiglia da un litro e mezzo costa 20 centesimi. Poi mi sono accorto che non avevo le bottigliette d’acqua per i bimbi quando vanno in palestra, e quindi nel pomeriggio ne ho prese sei da mezzo litro. Ogni bottiglia costa 18 centesimi. \u00c8 abbastanza facile dimostrare che il costo di un litro di quell’acqua \u00e8 minore o uguale a 2 centesimi, o se preferite a 20 euro il metro cubo: resta ora solo da calcolare quanto bisogna togliere per il maggiore uso di plastica nelle bottiglie grandi, il maggior costo logistico… e naturalmente per le bolle in pi\u00f9.<\/p>\n","protected":false},"excerpt":{"rendered":"
