In ecosystems, it is the diverse nature of multiple species co-existing in balance that stregthens, not weakens, the system. Monocultures can suffer the fate of an outside invading entity that can wipe out the dominant (i.e., only) species that exists. Thus, if something wipes out the existing monoculture, there is nothing to replace it via natural selection. Ever been in a "forest" consisting of only one kind of tree with no underlying plant and animal life to support it? Makes for a very one-dimensional existence.

The same goes for humans within a culture. Diversity is what strengthens the system, not what makes it weak.
