Il primo cantone svizzero a bandire le cannucce di plastica è stato Neuchâtel . Hawaii e California, da metà 2019, sono invece i primi Stati degli USA ad aver emanato una legge che obbliga ristoranti, bar e fast food ad utilizzare solo quelle di carta. Pensando al fatto che negli Stati Uniti vengono utilizzate cinquecento milioni di cannucce di plastica al giorno non può certo sfuggire l'importanza di quest'iniziativa che è già presentata come esempio, ma che non è ancora legge negli altri Stati americani.
Fatta la legge, c'è chi ha dato vita a un'impresa. A Los Angeles un'azienda ha recentemente iniziato la produzione di cannucce biodegradabili. L'abbiamo visitata e ci èstato mostrato con quale velocità e semplicità vengono prodotte. Il costo per il consumatore? È di poco superiore a un centesimo di dollaro a cannuccia. Un costo sopportabile pensando ai benefici che ne derivano, in primis, agli oceani.
