The OP said "fighting famine", not "fighting the famine". Without the definite article "the", their sentence can (and arguably should) be read as referring to famine as a class of calamities, not to a particular one.

As a further example, the job of a firefighter is to fight fires as they happen, not to help the UK forever recover from The Great Fire of London.

Take your ideology crusade elsewhere.
