Systems example: farmers are paid per pound for tomatoes. They therefore want to water heavily before harvest so the tomatoes get as heavy as possible. Then they ship the heaviest possible tomatoes to a factory to be dehydrated into ketchup, sauce, and other canned goods.

The energy loss comes in 3 different parts - water waste, extra fuel in shipping, and in energy to dehydrate. Everyone pays more.

The system solution would be to price the tomato solids, not the water.
