Yes, but there is zero shot at doing this versus energy and transportation.

The major limiter of veganism is cultural. People love eating meat. It’s a major source of protein and calories, especially in developing countries. Americans are not going vegan, so it’s kind of silly, in my opinion, to focus on it as a solution.

Compare to building nuclear energy or solar / wind + batteries. China, the US, Europe, and India are all well-positioned to do this. The limitation is political will, which is more difficult than it should be, but definitely easier than convincing a critical mass of Americans to go vegan.
