Even if we knew how to survive. Between private property, most wildlife being eradicated, the rest being protected, loss of natural ecosystems to farmland (private property) and ranch land (private property), commercial fishing reducing the abundance of fish available, other areas being protected from fishing, rivers being dammed up or polluted, water tables dropping due to the pumping of ground water, and our sheer numbers. Perhaps Living like hunter gatherers is no longer a choice available to us. It is either live as we do now, or perish. I know that is how it would be for me.
It's a sobering thought.
Once we became runaway successful, that tension between a need to be active & a desire to be idle started to disappear.
It probably helps that many (though by no stretch all) horses are very well taken care of and have a job to do. Show animals on the other hand (horse or dolphin) have a long track record of abuse, exploitation, neglect, and boredom.
