I would slightly amend this:

Eat meat, but only meat that is sustainably raised. Depending on the size of your lawn, you probably can raise a couple meat or egg chickens on the natural flora/fauna in your yard and table scraps. There are CSAs that raise only pastured eggs/chicken/hogs/beef without fossil-based grain inputs.

Meat is healthy, but yes, it is fossil-intensive in the modern era. But it doesn't have to be. There are zero-fossil options.
