Would you please tell me what "perform heroically" in the paragraph below means?
Even if I looked them up in dictionaries, I couldn't find out a proper meaning for that.
To be sure, there are organizations — the United Nations High Commission for Refugees (UNHCR), UNICEF, and many other groups — that, working together, perform heroically. And organizations like the Global Partnership for Education, Sheikha Mozah’s Educate a Child foundation, and the Global Business Coalition for Education also contribute in times of emergency. But that woefully small1% figure means that the world simply does not have enough to ensure that more than a fraction of affected children get help.
Thanks in advance.
