There is a considerable urgency to making this transition to a human-scale food system. While many are generally aware that our current means of producing and distributing food is unsustainable, few seem to realize that what cannot continue will not continue, that the limits are already being reached, and that the effects will most certainly be felt in our lifetimes, even in what are now wealthy countries. This is not an issue where we can continue business as usual and expect the impact to be felt only by distant populations or by subsequent generations. It will be one where we must take personal responsibility for change, both for our own benefit and that of society in general.
