Da almeno 5 anni l’Africa australe è in preda a una grave siccità che ha prosciugato diversi corsi d’acqua. La causa: i cambiamenti climatici. A rischio potrebbero esserci anche le celebri cascate del Lago Vittoria tra lo Zambia e lo Zimbabwe. Un tweet del presidente dello Zambia, Edgar Chagwa Lungu, e alcuni reportage hanno creato un po' di inquietudine sulle sorti delle cascate. Nel 2019 sembra che il turismo legato alla zona sia calato del 25%.
Per correre un po’ ai ripari, alcuni operatori turistici hanno lanciato su Twitter un nuovo hashtag #VictoriaFallsIsNotDry ovvero le cascate Vittoria non si stanno prosciugando, dimostrando con foto e video qual è la reale situazione.
Secondo il presidente dello Zambia c’è ancora speranza: occorre però che tutti agiscano insieme e che i paesi ricchi aumentino gli sforzi per contrastare le conseguenze del riscaldamento globale, aiutando così anche i paesi più poveri.
