If you want civilization to continue, remain civilized.
There will always be uncivilized people. Uncivilized people do the things that uncivilized people do.
But if we remain civilized ourselves, that is the start of civilization.
When I say civilized, I mean being civil to each other. Humane. Humanism. Decency. It is the standard of living we can have in any economic status, in any culture, in any community.
