The USDA created the problem through regulating industry consolidation. The 'fix' is to reconfigure the economy to price in unpriced negative externalities and create sustainable industries. This of course won't happen.
What was such a reconfiguration of the economy actually mean in real terms?
In practice the example I like to use is soil loss. Farming isn't sustainable because the soil literally blows and washes away and cannot be regenerated. The solution is to have forest patches to reduce the wind speed and marshes to hold the rain. All of this takes valuable land which cannot be used 'productively' but is vital to make agriculture sustainable.
