I consider both industrial meat production and veganism to be sub-optimal across all dimensions. I've recently jumped into this growing niche market for more sustainable and ethical meat. It's a little more pricey, unless you buy in bulk (e.g. 1/4 to full cow at a time), but I think it's worth it in the end.

I'm looking to share sources of info and network of producers/farms in this regard. Allan Savory has the Savory Institute which I found to be a good start. Though FYI there have been back-and-forth essays written about the criticism and defense of these practices (too many to post here but easy to find in the two above links).

I found one local family-operated farm that practices e.g. "organic" (in this case no herb/pest/fungi-cide) farming (crops for the animals), legitimate free-roaming chickens and sustainable land management that allows soil and ecology equilibration (reducing fertilizer use and subsequent runoff). Plus, buying and directly supporting local farmers and ranchers is always a plus!

EDIT: I foresee this thread being hijacked towards a discussion about how "meat is bad" and how we eat too much meat etc. I am being narrow here because I want to be pragmatic, rather than opine on global economics and dietary needs.

From the environmental standpoint shrinking of human population is often quoted to have desirable effects, and that's reasonable. But from the point of view of our daily lives and functioning of the human society, what negatives could we then expect? (I mean a soft decline due to lower birth rates, not some abrupt events.)

For example, with smaller population fewer music albums could be made every year than some time before, and people would maybe feel less inspired and satisfied. Less scientific research, less choices for relationships... and maybe other things? Would being more technically advanced compensate for the issues? Won't we feel ourselves in oblivion and romanticize the "numerous" past?
