I think the effort to get people to stop eating meat and XYZ favorite food isn't going to work. A lot of people eat what they eat because they don't really have much food choice. And with some people pushing weird options like bugs as a protein source while the rich will surely keep eating normal old burgers, life is starting to feel like a bad scifi movie.
I think the absolute biggest and most immediate solution is eating less. Not less beef. Not less pork. Just less of everything.
Obese people can easily consume 2x or more of the food a non-obese person takes in. In America alone, about 1/3 of the country is obese. Doing incredibly rough math here, cutting the calorie consumption of that top 1/3 in half would be the equivalent of 1/6 of food consumption vanishing. As someone from a rural family full of almost-carnivore 400+ pounders, getting them to cut their calories to ~2500 calories a day would be like half the neighborhood and their consumption simply vanishing.
And that's not even factoring in the gas we need to burn to accommodate the greater mass on airplanes, in cars, etc. Dropping the average weight of obese countries by 1/3 would put a big dent in emissions.
