explanation: the higher the "displacement" and "fuel consumption", the higher the "cost". the "heat" of the "food" affects the "taste", but the "taste" does not affect the "food" itself. the further away the "distance", the greater the "weight" and the higher the "postage". the factor of "climate" affects "latitude", and the factor of "ecology" affects "climate", but not the higher the "latitude", the better the "ecology". "health" is a factor that affects "nutrition" and "freshness", but higher "nutrition" is not necessarily more "healthy". in the case of excess "nutrition", it may be detrimental to "health".
