Readers react to the labeling of groceries report:
My first reaction is that Michael Le Page does not know what the hell he is talking about.
He starts by cheating with words: heated greenhouse grown produce “can” use more energy than produce flown in from “thousands” of miles away. Yes, if we make sure to waste a huge amount of energy in the greenhouse, and we somehow make that flight as short and efficient (and hey, maybe the airplane was already going that way) as possible.
Otherwise, it’s complete nonsense. Does he have any idea how much fuel a pair of jet engines gulp down per hour? Hint: lots. A Boeing 777 (twin engine) burns about $10,000 worth of kerosene in one hour.
So let’s say we flew some produce in from Arizona. That’s 1276 miles, not even “thousands”. Flight time is just over 3 hours. That’s $30k worth of kerosene. I bet one could heat a one acre greenhouse all winter in Minnesota for a less money (aka fuel aka greenhouse gasses) than that.
As for organic not being healthier — people argue both sides, but I know what I believe based on extensive reading on the subject. I believe I’m not ingesting as many man-made chemicals, most of which are harmful to my health. This can be discussed at length elsewhere.
And organic for environment? Sterilizing millions of acres of top soil with glyphosate (RoundUp) hardly seems good for the environment, yet is standard practice in the non-organic world. This too could be discussed at length.
Another reader:
He says yields on organic foods are lower. Proof? I contend he is making it up. Organic farming resulting in higher greenhouse gas emissions than chemical? Proof? This dude gets less believable by the paragraph. Climate labeling? Whose standard will be used? Not a bad or good idea, outside of the concept that some people will pay attention to some labels. It sounds as if LaPage is making a name for himself, not for the issues he’s discussing. If there is a new label every year for the “trendy” concept, people stop paying attention to any of them. Strawberries in January are not a bad idea, but the cost should reflect the actual input of flying them in from a warm place. There are plenty of heated greenhouses which use “waste” heat from power plants and other industrial processes. There are also unheated greenhouses which are insulated/double-walled and grow cold-tolerant plants for winter markets. In Maine.
I did check and Mr. Le Page is listed as a staff reporter for NewScientist.
