Veganism is funny. Some vegan food, such as avocados and certain nuts (cuisine definition; not botanical) such as almonds require a lot of water to grow, and also there's the transport problem. Although that one's a paradox: a transport ship might seem like its terrible for the environment, but its actually quite efficient compared to an airplane or every customer using their car to drive to the grocery store (though via local consumption it can be avoided). In this respect, individual responsibility matters, you can make a difference in various ways. Don't use fast shipping by airplane even if you can easily afford (only do it by exception), you can also sometimes pick train (e.g. from China, via Russia to Europe). You can do grocery shopping perhaps by bicycle instead of car. Other non-vegan food, where no animal got farmed (a free range chicken a family holds) is thrown away or not eaten (even though it was already produced), foods with trace elements (e.g. milk sugar) is avoided, foods with by-products such as gelatin or whey is avoided. But they drive in a train powered indirectly by coals (electricity network), or use a bus with tires made from pigs. And that's somehow fine (as long as they don't know it). What it boils down to is impact of choice, and simplicity of implementing it. Avoiding eating meat is a lot easier than avoiding any animal (by)products, therefore I find veganism self-defeating, and a luxury (first world) problem as well. No normal, average human being is going to have time to care enough about this issue to put the effort in it, its unreasonable. What works? Taxation, for example. If I'd drive a SUV instead of something small like a Ford Ka or Nissan Kia then I'd be paying a lot more per km on fuel, and for what gain? Its not worth it for me. But Americans barely pay any tax on their fuel.
