An article in the Independent points out that organic farming is in many cases worse for the environment than conventional methods. This is primarily due to the fact that organic methods are much less efficient, and therefore consume more energy and land:
Similar findings were recorded with organic chickens, where the longer growing time means it has a higher impact on all levels, including producing nearly double the amount of potentially polluting by-products and consuming 25 per cent more energy.
Vegetable production was also highlighted as a source of increased use of resources. Organic vine tomatoes require almost 10 times the amount of land needed for conventional tomatoes and nearly double the amount of energy.
It is important to understand that buying organic foods is not a choice of greater morality. Rather, it is a decision to buy a nicer product at a premium price. It is a boutique product for people of means.
Which I think is a fine thing, but it should not be conflated with making a moral decision. I can afford to buy a nice suit. I can drink single malt Scotch. I can buy a tricked out computer. And I can buy organic tomatoes. None of these makes me a better person.
In the rich West, we've moved far enough up Maslow's hierarchy that we can eat not just for sustenance, but for self-esteem.
If we do want to imbue morality into our food choices, we should should be doing everything we can to improve the efficiency of food production to bring down the price. Between 1 and 2 billion people on the planet still do not have enough to eat, which is an economic problem. The problem exists in places where agriculture is difficult and/or where economic systems do not reward production.
Put it this way: to those for whom money is an object, an affordable, conventionally grown green pepper provides a lot more value than an unaffordable, organic one.
Penn & Teller do an excellent job making this point, with a guy named Norman Borlaug:
