This is all of this, but not THE single pressing climate issue, food is the one issue where most people from most economies have already cought up, besides some excessive outliers, there is little to catch up in consumption worldwide and it's still a low percentage on climate impact. The big consumer driven issues by climate impact are all other consumption housing and transportation. If we want to allow the rest of the world to catch up to our standard of living, food choices is not the one area where radical change is needed to make this sustainable.
