It may surprise you, but the prices we pay at checkout for our foods are often quite different from the actual prices we pay for them as a society. Some of those costs are paid by governments in the form of subsidies for commodity crops or animal feed; others we pay more indirectly as medical expenses, as the costs of cleaning up water pollution, or of mitigating the damage done by global warming, for example.

The New York Times recently published an accounting of some of these hidden environmental costs in our foods. Partnering with True Price, a Dutch non-profit, they compared the sticker prices of five common grocery items to the estimated total cost of those items when greenhouse gas emissions, water usage and the effects of land use on, especially, biodiversity are factored in. Notably, they did not attempt to estimate the medical costs or benefits of the consumption of the various foods. Thus, their estimates are very probably low for foods known to be associated with health problems, high for others known to reduce risk for such problems.

We’ve taken the liberty of adapting the NY Times’ analysis to Canadian prices, expressed in Canadian dollars. Advertised prices at a Real Canadian Superstore in the Vancouver area were used as the sticker prices; the further environmental costs of the foods were arrived at by simply converting the NY Times’ published values to Canadian dollars.

Here are the results:

Food Item	Sticker Price per pound	Estimated Environmental Cost	Total Price
Ground beef (medium fat)	$6.49	$29.95	$36.44/lb
Cheddar Cheese (medium)	$7.93	$5.11	$13.04/lb
Chicken ‘drumsticks’	$4.49	$2.49	$6.98/lb
Tofu (medium firm)	$2.79	$0.29	$3.08/lb
Chickpeas	$1.51	$1.10	$2.61/lb

As is blatantly obvious from the table above, the actual costs of animal products to society are far higher than the prices the consumer pays at checkout. This is mostly due to the gross inefficiency of feeding farmed animals plants instead of growing plants for direct human consumption.

For every 100 grams of protein we get from beef, for example, 2500 grams of protein were consumed by the cattle. It takes an enormous amount of land to provide that protein to the animals – land that might otherwise be allowed to return to the wild; land that could be removing carbon dioxide from the air, that could be allowing biodiversity to increase. Contrast that to tofu, the production of which we could scale up very, very quickly were we to stop feeding soy to cattle and chickens instead.

As is very clear from the numbers presented here, the true prices of animal products are prohibitively high in the long run. We may not be paying them at the checkout counter, but we’re sure paying for them in other ways. It would be dramatically better were we not incurring those environmental costs in the first place. If we choose to prioritize plant-based foods in our society, we can accomplish precisely that.
