The point is that it's not sustainable.

We can't feed the world with a meat only diet.

There are other diets that are more sustainable.

People who switched to a meat only diet usually cut out junk and highly processed food - of course you're seeing a more positive change.

Don't eat highly processed food, reduce saturated fat and reduce sugar intake.

Parent wasn't talking about the climate or sustainability at all. My point is that that's not what the conversation is about. The parent was talking about _health_, not climate. Sustainability of meat industry is irrelevant completely to healthiness or non-healthiness of being a human carnivore.

And yet how we feed ourselves is tightly linked to the climate crisis.

You can't disconnect the two unfortunately.

Here is an interesting graph from IPCC's data showing the impact of various diets on green house gas emissions. https://www.nature.com/articles/d41586-019-02409-7
