The fact that there's plenty to do does not mean the ratio effort/impact on the environment is worth it.

Switching to a plant based diet is almost equivalent to eating half as much of an omnivorous diet : https://www.nature.com/articles/s41598-017-06466-8

However, dividing omnivorous food intake by two would probably not be possible in the long term, unless your diet is way oversized.

And it's easier to switch to a plant based diet than to be constantly hungry.

Reducing environmental impact is a marathon, not a sprint : it s much better to take actions that can be sustained in the long term than very impressive actions that are marginally more effective, but abandoned after 2 month

The improvement is way bigger than that for most meat-intensive (e.g. American) diets.

no one is talking about being hungry. I'm talking about reducing food waste and eating less in light of the massive obesity endemic. eating plant based can be a part of that, sure, but isn't directly related to my point.
