I find it interesting that, largely, those who are so enthralled by protecting their natural resources are also those that believe that globalization is the direction humanity should go.
The more you open your locality up to global resources the more you risk your locality.
Not a poke at California but fifty years ago if a farmer did things wrong and sent out Romaine Lettuce that was infected with a life threatening bacteria his customer base was maybe a few hundred people. Earlier this year there was a nationwide recall on Romaine Lettuce that was produced by a California based grower. Over 300 million people were potentially in danger.
It's great for California that it is the food basket for the USA but it sucks if you are a victim of the failure of big business' policy of centralization. It's time to realize that centralization is dangerous and we need to step back a little and understand that if there's a single producer of anything there's a single point of failure.
