A good family farm produces more, in net terms, than the farm family consumes. The good farmer has secured enough land to grow crops and support his or her livestock. The extra production beyond the farm family’s own consumption can be sold and traded for other goods and services—TVs, clothes, books. Some countries are like good family farms, with more bio-capacity than what it takes, in net terms, to provide for their inhabitants. Compare this with a weekend hobby farm, with honeybees, a rabbit, and an apple tree, where most resources have to be bought from elsewhere. Presently 80% of the world population lives in countries that are like hobby farms. They consume more, in net terms, than what the ecosystems of their country can regenerate. The rest is imported or derives from unsustainable overuse of local fields and forests.
