I'm pretty much giving up trying to discuss this topic with anyone anymore. If you're interested in the possiblities for future agriculture, please read these books:

Permaculture: A Designers' Manual by Bill Mollison

Grow More Vegetables by John Jeavons

The One-Straw Revolution and The Road Back to Nature by Masanobu Fukuoka

One Circle by David Duhon

The New Organic Grower and Four Season Harvest by Eliot Coleman

You Can Farm and Pastured Poultry Profits by Joel Salatin

Water For Every Farm by P.A. Yeomans

New Roots for Agriculture and Becoming Native to This Place by Wes Jackson

And, Sustainable Agriculture and Resistance: Transforming Food Production in Cuba, by Funes, Garcia, Bourque, et al,
which describes the adaptations made in Cuba when their supply of fossil fuels was cutoff following the collapse of the of the former Soviet Union. This book offers lessons and hope to all the rest of us in a post-PO, energy starved world.

Don't give up! It just takes time for new ways to be accepted. Have you seen this one? I want it SO bad!!!
