Green - An environmentalist community

If we only raised enough animals to eat our waste, you’d have a great point.

I have a good point, anyway. besides our waste, there is also a great deal of ag land that is unsuitable for crop cultivation. my point is still the same: using the metric of land use is not a great way to understand efficiencies in the agriculture sector. I don't believe any single metric is the key, probably.

off the top of my head, multigenerational ecosystem stability without artificial inputs might be the metric id aim to achieve, but it's hard to say what kinds of impacts that might have (efficiency would surely be impacted). given the vastness and interdependency of the modern agricultural system I don't believe any radical change is prudent. if the issues we are facing from carbon emissions are what we are looking to address, I would say we need to focus on other sources of carbon emissions primarily, rather than upset the agricultural system.
