If you haven't heard of pink slime it is the ammonia-treated ground beef filler that is used in school lunches and sold at a grocery store near you. In fact, some estimate the product is found in as much as 70 percent of the ground meat in the United States.
As awareness about pink slime has grown in the past week, other issues about industrial food processing have come to the forefront as well. While we don't like to know how the sausage is made, not knowing is a choice that could be toxic for our health, and toxic for the environment.
For instance, anywhere from 18 to 50 percent of greenhouse emissions come from livestock. The more humans there are, the more livestock is consumed. So how do we stop this cycle? Big Thinker Matthew Liao has a forthcoming paper that argues human engineering is the answer.
In other words, if pink slime isn't gross enough to make you stop eating red meat, there are nausea-inducing pills to reduce your appetite. That is one of a number of possible solutions we explore in today's lesson.
