I would place the emphasis differently. Preventing harm to Western Civilization is a great challenge.
The modern term "culture" is based on a term used by the Ancient Roman orator Cicero in his Tusculanae Disputationes, where he wrote of a cultivation of the soul or "cultura animi," using an agricultural metaphor for the development of a philosophical soul, understood teleologically as the highest possible ideal for human development.
Philosopher Edward S. Casey (1986) describes: "The very word culture meant 'place tilled' in Middle English ... To be cultural, to have a culture, is to inhabit a place sufficiently intensive to cultivate it—to be responsible for it, to respond to it, to attend to it caringly."
Culture as E.B. Tylor would have it, is "that complex whole which includes knowledge, belief, art, morals, law, custom and any other capabilities and habits acquired by man as a member of society."
Culture has this dual aspect. It is at the same time a cultivation of both the community and the self. The very roots of the word point towards the fact that we are, in a real way, the children of Rome.
