Salvare il pianeta dalla plastica è solo una questione di volontà. Lo dimostra quanto è successo domenica alla maratona di Londra dove, nei punti di ristoro, sono state distribuite ai 56'000 partecipanti circa 30'000 piccole bolle sferiche, commestibili (che contenevano acqua o altre bevande energetiche) al posto delle classiche bottigliette.
La svolta green ha avuto un impatto positivo sullo spreco di plastica "usa e getta", e quindi altamente inquinante, durante la competizione.
Le bolle commestibili sono completamente biodegradabili, prodotte da una start-up londinese (Skipping Rocks Lab), che le ha battezzate ooho. i "palloncini" sono realizzati con alghe marine e cloruro di calcio e possono contenere qualunque liquido (acqua, bibite). Il materiale è meno caro della plastica (2 centesimi al pezzo). Una pellicola a doppio strato rende il prodotto igienico.
