Thresholds are not only present at our feet when we carelessly go from
one room to another in our homes. Thresholds may be discrete boundaries
and yet have a fundamental impact when crossed. From light into
darkness; from warm into cold; from culture into barbarism. Thresholds
play a fundamental role in climate change, in human societies, in animal
populations. Wherever there is change, there are thresholds.
