Before you tuck into your next hamburger, best think about the consequences. We're not just talking about your waist line: research suggests that the beef industry is negatively impacting the environment, on land and sea, and it's not going to get better on its own.

The Center for Investigative Reporting illustrates the facts -- which include how cow farts are (seriously) a big problem -- in the below video, which is cleverly animated and manages to be funny and informative at the same time. Did we mention cow farts?

As the video shows, the worst costs of eating a hamburger are hidden. They come in the form of pollution, gas-guzzling transport systems and health care costs. Before we say any more, watch the video and decide where you stand on the issue.
