5.2.19 (HL)—Traditional vs. global food needs

A sustainability claim is incomplete until its ecosystem, community, time horizon and population scale are named.

A practice can protect local resilience yet fail at regional demand, or yield strongly now while creating long-term external costs; scale changes the verdict.

A low-input farm may sustain its soil for one family but not supply a growing city without imports or higher pressure elsewhere.

Ask sustainable for whom, where, for how long and at what throughput.

Neither low input nor high yield is a complete sustainability verdict.
