In the case of farming, I think that sustainable *means * that the land will
maintain its output, given *present* level of inputs, indefinitely. This means
that Having to add ever increasing level of fertizers amd pesticides to stay
where we are is nonsustainable. Organic farmers have shown that soil quality
improves when chemical agriculture is replaced with "organic" methods. One
does trade off greater labor costs (organic) for chemical/fuel costs (non
organic), but labor is inherently "sustainable" (available indefinitely,
as long as people exist), while chemicals are not.
