Meatless Mondays is a dead-simple strategy. Anyone can do it, and it doesn’t require major sacrifice. Even if you eat a typical American diet replete with processed, junk and fast food the other six days of the week, going meatless on Mondays will still cut your carbon footprint, improve your health and reduce demand for factory-farm meat.

Anyone can cook, and most everyone should.

The USDA is not our ally here. We have to take matters into our own hands, not only by advocating for a better diet for everyone - and that's the hard part - but by improving our own. And that happens to be quite easy. Less meat, less junk, more plants.

The truly healthy alternative to that chip is not a fake chip; it’s a carrot.

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.

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.

I'm not a vegetarian. Now, don't get me wrong - I like animals. And I don't think it's just fine to industrialize their production and to churn them out like they were wrenches. But there's no way to treat animals well when you're killing 10 billion of them a year. Kindness might just be a bit of a red herring. Let's get the numbers of animals we're killing for eating down, and then we'll worry about being nice to the ones that are left.
