Whilst many were simply frustrated by the UN climate talks in Warsaw last winter, Filipino civil servant Yeb Saño emerged as an unlikely star with his dramatic hunger strike. A typhoon had just obliterated his hometown, and Saño broke down in tears and declared he would fast until “we stop this madness” and the UN talks produced more concrete results. What he would make of this new global stardom was uncertain, but he emerged as a charming and inspiring global voice. Many have followed his lead, and a growing fast for climate movement where people collectively fast for a day at the start of every month. Initially trained as a lawyer, he came to the Filipino government via the WWF and, aside from the drama of the hunger strike, remains an important voice in future talks, if only for the Philippines he represents.
