That’s reasonable, but from my perspective at least one of those requires a change to human nature, and my filter for solutions includes a key statement that anything which requires human nature to change is non-viable. Plant-based diets require an extraordinary number of people to make up their individual minds to do something that they’d prefer not to do. That’s not reasonable or pragmatic.

I might look at food waste, but I’ve dealt with this subject 2–3 times and find that health regulations and liability are fundamentally problematic in this space, and that those health regulations are liability are bound up in complex regulatory webs. It’s unclear to me that there are good food waste reduction approaches. And it’s unclear to me they are substantive compared to the other solutions.

Drawdown is excellent, but imperfect. It’s also focused differently than my list, which is purely big hitters, not a cost-benefit analysis.
