Oak --you forgot the bears in North America --deer predators. There's enough of them in various parts of North America.

It's great a lot more people are vegetarians --meaning for years. That's real commitment which like cycling ...just becomes part of daily life.
I've scaled down a lot from having meat nearly every dinner to several times a month ...now like this for past 15 years or so. It was more just eating less meat for health reasons and just saving costs.
