Sure, and I'm not arguing against vegetarianism, I think that's a great choice. I've been on and off a vegetarian diet for some time. It is definitely the most sustainable and safest option. But many people are very opposed to the idea for one reason or another, so I believe that encouraging a wide range of sustainable practices within their lifestyle is a good place to start. As more and more plant-based options become available, hopefully a lot more people will come around to the idea that vegetarianism is easy, affordable, ethical, and sustainable. That said, as someone who believes all these things, sometimes it's easier said than done - it takes effort, which is a barrier to overcome.
