Can local food be as efficient as industrial agriculture?
Here’s l;ink to a discussion of this interesting topic.
Probably some foods are more efficiently produced locally and some others via industrial farming.
The way to determine which is which is to remove all agricultural subsidies. Then the prices in the stores would reflect the true costs of growing each item and each of us could make our decisions according to our own values.
By the way last summer I purchased local; strawberries which cost more than the imported variety because the local ones tasted better.
Seven billion are a lot of people to feed and it could well be that industrial agriculture is necessary. And should it fail it would also mean a lot of suffering..
