Public support for regional farms is the best investment we can make. Conversion of topsoil into suburbs is an attack on future generations. Were a full food crisis to overtake the nation, local farms, community gardens and greenhouses, aquaculture and urban orchards could help to keep us alive. Every city should plant fruit trees and edible berry bushes in public spaces, along roadways and in vacant lots. Water Water districts should stockpile a year's supply of fuel, while sponsoring water conservation measures.
Homeowners can also conserve water by installing cisterns to catch rooftop rainwater.
In Australia and much of the world's equatorial countries, a large percentage of the domestic water supply comes from rooftop catchment. The auto industry, like many other computerized manufacturers, does not maintain inventories of parts. If the parts don't arrive, the assembly lines shut down. Fueling cars, trucks and snowplows could become problematic. If fuel shortages immobilize private cars, mass transit would be essential to move people and goods efficiently.
