Slaughterhouses human toll, chatty baboons and plant-based pollutions

You can listen to this episode above or by subscribing to the podcast on Itunes or Stitcher. You can also find episodes of VeganSci on Soundcloud and Omnystudio. (52mins, 73mb)

In this episode of VeganSci, we update you with some Quick Science, including: a close look at the highly publicised chimera pigs paper, a new take on the evolution of human language, the promise of B12 fortified toothpaste, and consumer’s understanding of meat-based proteins impact on the environment.

We get stuck in-depth on a paper that evaluates the pollution created through the production of animal-based foods compared to plant-based foods, and a second paper that describes how slaughterhouse workers report higher rates of negative physical and psychological well-being than other job types.

And finally in the bullshit corner we tackle that infamous issue of where vegans get their protein!

You can find links to all of the research we discussed below.

In the comments section below let us know if we missed anything, got something wrong or if you want clarification on any of the points discussed.

Bullshit Corner (45:35 - 49:47)

Blackbeens do have lots of iron and protein (48% daily recommended intake; 21g per/100g), with a better rate of iron but not protein when compared to cow flesh (14% daily recommended intake; 26g per/100g) – values are based on wikipedia nutrition facts.
