I live full-time in the world of omnivores, and I've never wanted to leave. But the Standard American Diet (yes, it's SAD) got to me as it gets to almost everyone in this country.

50-100 years from now we are all going to be eating a plant based diet. Whether that happens through a catastrophe or a peaceful sustainable life giving way is based on whether we make the right choices now and how we fight in this struggle together.

We need real farmers who grow real food, and the will to reform a broken food system. And for that, we need not only to celebrate farmers, but also to advocate for them.

Our demand for meat, dairy and refined carbohydrates - the world consumes one billion cans or bottles of Coke a day - our demand for these things, not our need, our want - drives us to consume way more calories than are good for us.

We need to demonise soda, the way we've demonised cigarettes.

If you're a progressive, if you're driving a Prius, or you're shopping green or you're looking for organic, you should probably be a semi-vegetarian.

1 billion people in the world are chronically hungry. 1 billion people are overweight.
