Our diets are meant to be balanced, not overloaded with meat or confined to vegetables. As is true throughout nature, we should practice moderation and take only what we need.
I detest industrial farming and wish the animals to live more natural lives, ended with quick painless deaths when they are mature. We need to reduce, not eliminate, our consumption, and treat our food animals - as well as our food plants - with respect, as was done on farms and by native peoples for millennia.
For every action, there is an equal and opposite reaction. Our disrespect for other life forms has widened to include ourselves and their revenge comes in the abundance of factory food that is killing us.
We are part of nature, no matter how much we convince ourselves that we are distinct or disconnected. We must work within it, not against it.
