Quanto tempo ci vuole perchè una bottiglia di plastica si biodegradi in mare? - Il giornale del mare
Skip to content Sapete che i frammenti derivanti dalla degradazione dei diversi materiali, se ingeriti dai pesci, finiscono nella nostra catena alimentare? Ogni anno milioni di rifiuti vengono abbandonati sulle spiagge. Plastica, vetro, lattine, pile esauste, borse della spesa sino a televisioni e frigoriferi abbandonati da persone poco civili. Ma quando nessuno puo’ recuperarli questi rifiuti entrano della nostra vita, nel nostro cibo. Le microplastiche ad esempio vengono ingerite dagli animali marini come pesci o molluschi. Una volta ingeriti queste microparticelle tossiche entrano nella catena alimentare arrivando sino ai nostri piatti.
Ogni giorno circa 8 milioni di tonnellate arrivano in mare ma non e’ soltanto colpa di chi abita le zone costiera. Infatti, ben l’80% di tali rifiuti arrivano dall’entroterra tramite i fiumi. Per prendere coscienza del tempo che impiega un rifiuto per sparire totalmente abbiamo preparato questa semplice infografica.
Carta igenica Da 2 a 4 settimane Cartone del latte Da 1 a 5 mesi Fiammiferi Da 10 a 14 mesi Mozzicone di sigaretta Da 1 a 3 anni Pile esauste 200 anni Plastica 400/450 anni
L’urgenza del problema globale della plastica Gli autori dello studio seguente Roland Geyer, Jenna R. Jambeck e Kara Lavender Law hanno stimato che dal 1950 al 2016 sono stati prodotti 8.300 milioni di tonnellate di materie plastiche e che la stragrande maggioranza sia finita in mare. Sin dalla sua invenzione nel 1907, la dipendenza mondiale da plastica sta travolgendo il nostro pianeta. Quali paesi contribuiscono maggiormente all’inquinamento da plastica? Circa 8 milioni di tonnellate di plastica vengono scaricate negli oceani del mondo ogni anno e la maggior parte di questi rifiuti proviene da soli sei paesi: Cina, Indonesia, Filippine, Vietnam, Sri Lanka e Thailandia. (Jambeck et al, 2015).
Un grande paese come gli Stati Uniti è solamente al 20° posto per l’inquinamento degli oceani da plastica. L’Italia è invece lontana da questo triste primato.
Cosa possiamo fare Data la quantità di plastica presente a livello globale, il costo della sua rimozione dall’ambiente è proibitivo. Per tale motivo la soluzione sta anche nella prevenzione. Ecco cosa possiamo fare a livello individuale per proteggere i mari e gli oceani dalla plastica .
Utilizzare buste riutilizzabili Ogni minuto vengono utilizzati circa 1 milione di sacchetti di plastica e un singolo sacchetto di plastica può impiegare sino 1.000 anni per degradarsi. Utilizza i sacchetti che hai in casa per fare la spesa e non li buttare.
Attenzione alle microsfere di plastica Queste piccole perle di plastica si trovano in alcuni prodotti per il viso, saponi, gel doccia e dentifrici. Sono molto piccoli, quindi non possono essere efficacemente filtrati dai rifiuti prima che entrino in fiumi, laghi o oceani.
Una lettera alla politica Scrivi al tuo legislatore per l’impostazione delle politiche di protezione ambientale, in particolare sui rifiuti di plastica!
Riduci, riutilizza e ricicla Riduci il tuo utilizzo di materie plastiche, riutilizza i prodotti di plastica quando possibile, ricicla tutta la spazzatura che puoi!
Usa bottiglie e bicchieri riutilizzabili L’acqua in bottiglia produce 1,5 milioni di tonnellate di rifiuti di plastica all’anno e queste bottiglie richiedono 47 milioni di litri di petrolio per produrre, secondo Food & Water Watch. Porta una tazza riutilizzabile nei bar e chiedi al barista di riempirla, e tieni una tazza sulla tua scrivania invece di usare bicchieri di plastica.
Pulisci le spiagge Uno dei modi in cui puoi aiutare gli animali marini a sfuggire ai pericoli della plastica è raccogliendo i rifiuti. Fallo con i tuoi amici o con la tua famiglia, il mare ti ringrazierà.
