I recently became a vegetarian in order to stop contributing to these cruel industries. I do still eat eggs sometimes, and local goats milk and cheese, but I stopped eating all my old favorites like steak, chicken and pork.
For me, it is about not harming any living creature, but I do not judge people that are unconscious and do not think deeply about the impact of their actions and purchases. Most people genuinely don't know and I just try and educate on the reality of what they contribute to when they shop. Many people are aware of the brutality they contribute to, but we are all on our own paths. I have been finding that most people engaged in conscious acitivity- things like meditation, yoga, tai chi, or any spiritual practice, often try and live low impact lives that harm nothing else.
I am sure if we all had to get our stuff fresh from the source, and saw the reality of how we pay to have our fellow creatures tortured and slaughtered, most of us would turn to the plethora of healthy protein sources instead that do not rely on killing animals.
Thats just like, my opinion man.
