Sustainable Beef?

Posted by in Uncategorized

As an environmentalist, or someone who cares about the environment; I understand that eating red meat is unsustainable. But as an athlete who grew up needing protein, I really enjoy eating red meat. So there’s this internal debate in my head with enjoying a steak and being environmentally friendly.

The Environmental Working Group (EWG) shows the full lifecycle greenhouse gas emissions from different types of proteins. As shown in the graph; lamb, beef, cheese, and pork emit the most greenhouse gases.

We learned in class that McDonald’s aims to purchase verified sustainable beef by 2016. But what does that really entail?  Why is beef unsustainable?

Feed production and manure both contribute to greenhouse gas emissions. Most livestock are fed fishmeal, corn, soybean meal and other grains. Grains in particular require fertilizer, which when applied to soil, creates nitrous oxide (N₂O). N₂O has 300 times the warming effect that carbon dioxide does (Environmental Working Group, 2011). Manure also releases N₂O and methane which pollutes our water and air. The Environmental Working Group (2011) states that 90% of beef’s emissions occur during the production process as seen in the graph below.

Another reason that beef is generally unsustainable is that a lot of the animal is wasted when we consume beef. However I can’t see McDonald’s customers wanting every part of a cow in their burger. McDonald’s has already experienced a lot of backlash in regards to what their food is made of.

I personally think that it’s great that McDonald’s is aiming to purchase sustainable beef by 2016. Switching to sustainable options within their wheelhouse of product offerings is a smart choice by McDonald’s. But the issue here is that not many consumers know that beef is unsustainable. Whose job is it to educate these consumers? As soon as a consumer thinks that a campaign can benefit the company directly they will have negative feelings towards the company. If McDonald’s starts to educate consumers about the negative impacts of consuming beef; will consumers believe it is a marketing ploy to gain a competitive advantage over other fast food chains? Doing good for the environment and good for your company seems to be a double edged sword in the opinion of consumers these days.
